目前,国内外还没有关于煤矿与油气井协调、安全和经济开采模式可以借鉴,资源重叠区开采油气资源遗留的废井严重地制约了煤矿的安全开采,正确处理井田内废弃油气井,对此类矿区降低开发成本,合理布置工作面,减少预留煤柱造成的煤炭资源浪费,消除安全生产隐患,具有重大的现实意义。以禾草沟煤矿为例,详细介绍了井田范围内废弃油气井的治理方法,以及在治理过程中遇到的困难,分析了开采过程中可能的安全隐患,并提出了针对性的建议。可以为类似矿区正确处理煤矿与油气资源开采问题提供参考。
At present, there is no domestic and foreign research on the coordination of coal mines and oil and gas wells, safety and economic exploitation modes can be used for reference, and the waste wells left over from the exploitation of oil and gas resources in the overlapped areas of resources seriously restrict the safe exploitation of coal mines and properly dispose of abandoned oil and gas wells in the fields It is of great practical significance to reduce the development cost of a mining area, rationalize the working face, reduce the waste of coal resources caused by reserving coal pillar and eliminate the potential safety hazard. Taking Hecaogou Coal Mine as an example, this paper introduces in detail the treatment methods of abandoned oil and gas wells in the minefield, as well as the difficulties encountered in the process of management. The potential safety hazards in the mining process are analyzed and some suggestions are put forward. It can provide references for the coal mines and oil and gas resources mining problems in similar mines.
