摘要

通过实例表明了详细查明地质构造是确保煤层瓦斯抽采均衡、避免瓦斯灾害的重要基础工作。提出了综合利用瓦斯抽采钻孔开展煤矿瓦斯地质精细勘查的主要任务、施工要求,以及采掘工作面前方隐伏断层探测和瓦斯抽采方案。隐伏断层探测方案的可行性得到了煤矿生产实践的验证。研究结果表明,综合利用瓦斯抽采钻孔对煤层顶(底)板实施连续探测,能够及时发现隐伏构造,是提高瓦斯地质勘查精度,防治瓦斯灾害的一种实用、经济和有效的技术途径。
It is an essential task to explore geological structures in detail in order to degas evenly in coal seams and prevent gas hazards in coal mines.The necessity of the meticulous gas geological exploration in coal mines has been shown through practical examples of gas hazards in China.Main task and requirement of the meticulous gas geological exploration project are put forward for comprehensive utilization of degas boreholes.The design patterns have been expounded upon exploring and dealing with concealed faults in front of tunneling face and in coal mining panel.Feasibility of the design patterns introduced in the paper has been tested and verified in coal mining practice.It is concluded that comprehensive utilization of degas boreholes for locating successionally roof or floor of coal seam could improve exploration accuracy of concealed geological structures,and that is a practical,economic and effective technical way to carry on meticulous gas geological exploration and to prevent gas hazards in coal mines in China.
