6.2 RISK ANALYSIS AND DISASTER MANAGEMENT PLAN

6.2.1 RISK ANALYSIS

Risk analysis is the systematic study of uncertainties and risks encountered in various

areas. Risk analysis seek to identify the risks involved in mining operations, to

understand how and when they arise, and estimate the impact (financial or otherwise) of

adverse outcomes. It also defines and analyzes the dangers to individuals, businesses

and government agencies posed by potential natural and human-caused adverse

events.

6.2.2 RISK PRIORITISATION BASED ON HAZARDS IN BAJRI MINING

Bajri mining is done by open cast semi-mechanized method. Mining is done only within

the Banas River stretch located near revenue villages of Tehsil - Piplu, District-Tonk,

Rajasthan. The lease area is 3342.10ha. There is no land degradation due to mining






activities as mining is done only on river bed surface. There will be no OB or waste

generation as the sand is exposed in the river bed. There will be neither any stacking of

soil nor creation of OB dumps. So, no dumping area as well as stock piling area is

required. Therefore, there is no chance of failure of dumps and no slope failure due to

OB dump and stock piling.

However, there are various factors, which can create unsafe working conditions /

hazards in mining of Bajri (minor minerals) from river bed. The following types of hazards

are identified during the Bajri mining operations:-

1. Accident during sand/mineral loading, transportation and dumping

2. Accident due to vehicular movement

3. Inundation/ Flooding

4. Quick Sand Condition

6.2.3 MITIGATION MEASURES

6.2.3.1 Measures to prevent accidents during loading

The following activities will be done to minimize the risk are:-

a. At the time of loading no person will be there within the swing radius of the

excavator/ JCB.

b. The dumpers/ trucks will stand near the loading equipment and fully braked when the

muck is filled in it.

c. The truck would be brought to a lower level so that the loading operation suits to the

ergonomic condition of the workers.

d. The workers will be provided with gloves and safety shoes during loading.

e. Opening of the side covers (pattas) should be done carefully and with warning to

prevent injury to the loaders.

f. Operations during daylight only.

6.2.3.2 Measures to prevent accidents during vehicular movement & transportation


a. The truck will be covered with tarpaulin and maintained to prevent any spillage.

b. To avoid danger while reversing the trackless vehicles especially at the embankment

and tipping points, all areas for reversing of lorries should be made man free as far

as possible.

c. The vehicles must be maintained in good repairs and checked thoroughly at least

once in a week.






d. All transportation within the main working will be carried out directly under the

supervision and control of the management.

e. Overloading should not be permitted and the maximum permissible speed limit

should be ensured.

f. The truck drivers should have proper driving license.

g. A statutory provision of the fences, constant education, training etc. will go a long

way in reducing the incidents of such accidents.

6.2.3.3 Measures to prevent incidents during Inundation/ Flooding


a. During monsoon months and heavy rains the mining operations are ceased.

b. There should be mechanism/ warning system of heavy rains and discharges from the

upstream dams.

Inundation of flooding is expected and beneficial for these mines as during this time only

the mineral reserve gets replenished.

6.2.3.4 Precautionary Measure for Sudden Release of Water from Upstream Dam


a. The mining should be done only during the dry season and under strict supervision.

b. Mining activities should be avoided during monsoon season.

c. No go zones should be clearly marked and made aware to the mine workers.

d. Deep water areas must be identified.

6.2.3.5 Measures to prevent sudden increase in water level


a. The mining activities will be restricted to 3m depth from river bed surface.

b. Mining activities will be avoided during monsoon season.

c. Mining will be done as per the approved Mining Plan and it will also be conformed to

avoid the ponding effect.

6.3 DISASTER MANAGEMENT PLAN

This should deal with action plan for high risk accidents like landslides, subsidence,

flood, inundation in underground mines, fire, seismic activities, tailing dam failures etc.

and emergency plan proposed for quick evacuation, ameliorative measures to be taken






etc. The capability of lessee to meet such eventualities and the assistance to be

required from the local authorities should be described.

� The shallow depth of activities in river bed mining will not involve any high risk

accident due to side falls/collapse.

� The complete mining operation will be carried out under the Management and

control of experienced and qualified Mines Manager having Certificate of

Competency to manage the mines granted by DGMS.

� All the provisions of Mines Act 1952, MMR 1961 and Mines Rules 1955 and other

laws applicable to mine will strictly be complied with.

� During heavy rainfall the mining activities will be closed.

� All persons in supervisory capacity will be provided with proper communication

facilities.

� Proper coordination with Irrigation Department will be maintained so that at the time

of releasing water, if any, from the dam suitable warning/information is given in

advance.

6.4 OCCUPATIONAL HEALTH HAZARDS

Dry- pit mining by open cast method involves dust generation by excavation, loading and

transportation of mineral. At site, during excavation and loading activity, dust is main

pollutant which affects the health of workers whereas environmental and climatic

conditions also generate the health problems.

Addressing the occupational health hazard means gaining an understanding of the

source (its location and magnitude or concentration), identifying an exposure pathway

(e.g. a means to get it in contact with someone), and determination of likely a receptor

(someone receiving the stuff that is migrating).

Occupational hazard due to sand mining mainly comes under the physical hazards.

Possible physical hazards are as below mention:-

6.4.1 PHYSICAL HAZRADS DUE TO MINING OPERATIONS

Following health related hazards were indentified due to riverbed sand mining operations

to the workers:-

1. Light: - The workers may be exposed to the risk of poor illumination or excessive

brightness. The effects are eye strain, headache, eye pain and lachrymation,

congestion around the cornea and eye fatigue.






2. Heat and Humidity: - The most common physical hazard is heat. The direct effects

of heat exposure are burns, heat exhaustion, heat stroke and heat cramps; the

indirect effects are decreased efficiency, increased fatigue and enhanced accident

rates. Heat and humidity are encountered in hot and humid condition when

temperatures and air temperatures increase in summer time up to 480C or above in

the river bed mining area.

3. Eye Irritation: - During the high windy days in summer the sand could be the

problems for eyes like itching and watering of eyes.

4. Respiratory Problems: - Large amounts of dust in air can be a health hazard,

exacerbating respiratory disorders such as asthma and irritating the lungs and

bronchial passages.

5. Noise Induced Hearing Loss: - Machinery is the main source of noise pollution at

the mine site.

6.4.2 MANAGEMENT

Medical help on top priority immediately after diagnosis/ accident is the essence of preventive aspects.

6.5 REPLENISHMENT STUDY

Replenishment Rate is the rate at which sand/ gravel is transported into the river

channel, due to sand extraction. Dandy - Bolton formula is used to calculate the

sedimentation yield which uses catchment area and mean annual runoff as key

determinants to give a yield value.






Figure 3.5: Watershed Area and Drainage Map of Piplu, Tonk District

6.5.1 DANDY - BOLTON EQUATION

Dandy Bolton formula is often used to calculate the sedimentation yield. But use of these

equations to predict sediment yield for a specific location would be unwise because of

the wide variability caused by local factors not considered in the equations development.

However, they may provide a quick, rough approximation of mean sediment yields on a

regional basis for preliminary planning. The accuracy of the sedimentation surveys

varied, ranging from reconnaissance type measurements of sediment deposits to

detailed surveys. Dandy- Bolton determined the combined influence of runoff and

drainage area on sediment yield to compute the sediment yield. They develop two

equations i.e. for run off less than 2 inch and for run off more than 2 inch, which are

given below:-

For run off less than 2 inches (Q < 2 in)






For run off more than 2 inches (Q > 2 in):

Where: S = Sediment yield (tons/ mi2/ yr)

Sr = Reference sediment yield value = 1645 tons/ mi2/ yr

Q = Mean Annual runoff (inch)

Qr = Reference Mean Annual runoff = 2 in

A = Net drainage area (mi2)

Ar = Reference Net drainage area = 1 mi2

The calculation of catchment area is based on SRTM data processed using ARCGIS

software. The mean annual rainfall of Tonk district is 566 mm as per Monsoon 2013

Report, Water Resource Department, Govt. of Rajasthan. The total run off which will

contribute in sediment yield will be considered as 75% of total rainfall i.e. 425 mm.

The computations for total annual suspended and bed load sediment yield are given

below:-

Sediment Yield:-

For run off less than 2 inches (Q < 2 in) For run off more than 2 inches (Q > 2 in)

Where:-

Q (in) = Mean Annual run off = 425 mm = 16.71 inch

A (mi2) = Catchment area= 10118.2531 km2 = 3906.65754 mi2

Sediment Yield, S (tonnes/ yr) = 1965 e - 0.055Q [1.43-0.26 log (A)]

S = 1965 e-0.055 x 16.71 [1.43 - 0.26 log (3906.65754)]

S = 15,19,023 tonnes/ year

Thus, 15,19,023 tonnes/ year sediment will be regenerated every year in the catchment

area as replenishment against the quantities mined out. The area 10,118.2531 km2 is

representing the catchment area of the Banas River in Tonk district. The total river

stretches on which mining activities will be carried out in the district is 128.2 km. The

lease area of Piplu mine stretches in a length of around 24.40 km. Therefore, the

sediment yield 2,89,112 tonnes/ year was calculated for the mine. The maximum annual

production is 56,00,000 tonnes/ year. The amount of sediment regenerated every year

will be 2,89,112 tonnes/ year in the catchment area. Therefore, the percentage of

replenishment is about 5% every year.

The hypothetical derivation of replenishment data is not supported by any ground

evidence as the same can be derived only after annual study due to inconsistent rains in






Rajasthan. The derived replenishment data is based on macro-watershed data taken

from satellite imagery with sample ground truthing and annual average rainfall. The data

works out to be around 5% which after detailed study will show some divergence. The

data derived is based on SRTM 30 m resolution processed using ARCGIS software with

linear and resolution factors affecting the derivation.

In addition to this, a preliminary replenishment study on River Banas was carried out by

Indian Institute of Technology (IIT), Roorkee on dated 18th

– 19th

June, 2014 by Prof. Z.

Ahmed, Professor, Civil Engineering Department, IIT Roorkee. After this preliminary study,

it has been concluded that “the intervening catchment of the Banas River i.e., from

downstream of Bisalpur dam to the confluence of Banas River with Chambal River shall

contribute sand to the Banas River through soil erosion and replenish the River if the sand

from the river shall be lifted/ mined.” In the light of above observation, a comprehensive

replenishment study is envisaged during the rainy season at least for few continuous

years as the river is seasonal not perennial to understand the pattern and potential of

sedimentation and replenishment.

6.6 TRAFFIC STUDY

A traffic study is an investigation to evaluate a transportation system. The study is a

means of identifying and documenting any deficiencies or improvements both-

operational and physical - necessary to accommodate current or projected traffic

volumes. Traffic impact study can be used to help evaluate whether the development is

appropriate for a site and what type of transportation improvements may be necessary. It

will help:-

� To establish the existing trips/ day without the project activity;

� To understand the increment on the traffic load due to the project activity;

� To know the existing road will sustain or not after the commission of the project.

6.6.1 INDIAN ROAD CONGRESS (IRC) GUIDELINES

Factors for conversion of different type of vehicle into equivalent passenger car unit

(PCU) based on their relative interference value as per Indian Road Congress

Level of Service (LOS)

Capacity standards are fixed normally in relation to the Level of Service (LOS) adopted

for design. Six levels of service are recognized commonly designated from A to F.

Considering the need for smooth traffic flow; it is recommended that normally LOS-C be

adopted for design of urban roads. At this level volume of traffic will be around 0.70

times the maximum capacity. Capacity or Design Service volume is the maximum hourly

volume at which vehicle can reasonably be expected to transfers a point or uniform

section of a lane or road way during a given time period. As per IRC 64: 1990 guidelines,

ratio of existing volume of PCU on roads (V) and its capacity (C) with corresponding

level of services (LOS) and their performance is given below:-

0.6 - 0.8 D Poor

0.8 - 1.0 E Very Poor

(Note: Capacity as per IRC: 64-1990)






6.6.2 TRAFFIC ANALYSIS AS PER IRC GUIDELINES

Traffic analysis is carried out by understanding the existing carrying capacity of the

roads near to the project site and the connecting main roads in the area. Then

depending on the capacity of the mine, the number of trucks that will be added to the

present scenario will be compared to the carrying capacity. The roads connect from the

mine site to NH-12. These roads are wide enough to facilitate easy and smooth

movement of heavy duty trucks. During mining operation, there are 80-85 trucks per

hour will be deployed from the mine site. Detail of truck capacity, no. of trucks and

working hours are given below:-

6.6.2.1 Traffic Scenario in Nearby Project Site

River bed mining is carried out in revenue villages of Piplu tehsil, Tonk district. Mined out

Bajri/ Sand are dispatched to the destination places via village road which finally met to

the highway NH-12. At present, the traffic load at village road and highway are 52 and

86 vehicles/hr. The traffic scenario with project & LOS are given below:-

Table 6.7: Traffic Scenario and LOS

V/C ratio

LOS

Village Road 138 250 0.55 C

NH-12 intersection 187 625 0.30 B

From the above analysis, it can be concluded that the V/C ratio is found to be 0.55 and

0.30 for village road and Highway respectively. So, the Level of Service is C & B

respectively for village road and Highway which is ‘good’ and ‘very good’, as per

classification. Hence, the load on the carrying capacity of the concerned roads is not

likely to have any significant adverse impact due to proposed project.
