摘要
针对低渗透性突出煤层瓦斯治理难题,通过理论建模与工程实践相结合,构建了覆盖钻孔优化设计、采空区动态管控及老孔修复的全链条防控体系。研究成果有效破解了低渗煤层瓦斯抽采效率低、治理周期长的行业瓶颈,技术经济指标显著优于传统方法,可为同类复杂地质条件矿井提供技术范式,对保障深部煤炭资源安全高效开发具有重要指导意义。
To address the challenges in controlling gas emission from low-permeability coal seams,this study developed an integrated prevention and control system combining theoretical modeling with engineering practices.The system encompasses optimized borehole design,dynamic management of mined-out areas,and rehabilitation of old boreholes.The research effectively resolves industry bottlenecks such as low gas extraction efficiency and prolonged treatment cycles in low-permeability coal seams.With significantly superior technical and economic performance compared to conventional methods,this approach establishes a technical framework for mines under complex geological conditions,providing crucial guidance for ensuring safe and efficient development of deep coal resources.
