AI Technical Summary
Existing technologies are insufficient for the coordinated management of disasters such as rock bursts, gas and water hazards. In particular, in extra-thick coal seams, single management methods are difficult to effectively prevent and control multiple disasters, and construction is complex and poses significant safety risks.
Directional drilling technology is used to open drilling sites on both sides of the tunneling face, determine the location of the target coal seam and carry out directional drilling to form main boreholes and branch boreholes. Combined with segmented hydraulic fracturing, advanced and coordinated control of rockburst, gas and water hazards is achieved.
By rationally arranging the main borehole and branch boreholes and employing hydraulic fracturing technology, we have achieved coordinated management of multiple disasters, including rockburst, gas extraction, water hazard prevention, and geological exploration. This has prevented potential hazards during coal seam tunneling and ensured construction safety.
