Borehole trajectory (profile view)Borehole trajectory (plan view)
A single hole with 77 sidetracks was accomplished in coal seam. Maximum of depth
of the borehole is 834m. The average drill efficiency reached 247 m/d. One single
borehole can cover the whole areas which reduced gas drainage cost significantly
4. Application
Multi-sidetracks in-seam directional drilling for gas drainage
