东部矿区煤炭资源深井开采可行性分析——以孔庄煤矿为例

Feasibility analysis of deep well mining of coal resources in eastern mining area:a case study of Kongzhuang Coal Mine

针对东部矿区煤炭资源供需矛盾问题,对江苏、安徽和山东省的深井开采现状、地质条件及主要灾害类型进行了深入调研,分析了东部矿区深井开采潜在瓦斯灾害、动力地质灾害、深部高压水害、深部矿井热害4类灾害对于深井开采的威胁。同时,以上海大屯能源股份有限公司孔庄煤矿(以下简称“孔庄煤矿”)为研究对象,列出了影响该矿深井开采的潜在风险清单,建立了基一套全面、完善、有参考价值的深井灾害防治体系;通过估算深部资源量、审视开采技术水平、使用SWOT分析等方法,对深部煤炭资源的开采技术、经济性进行了全面评估。研究结果表明,孔庄煤矿深部煤炭资源的开采技术与经济均具可行性,研究成果对于提高东部矿区煤炭自给能力,延长矿井使用期,保障地区经济稳定具有重要价值。

In response to the contradiction between supply and demand of coal resources in the eastern mining area,an in-depth investigation of current deep well mining status,geological conditions,and main types of disasters in Jiangsu,Anhui,and Shandong provinces was conducted,the potential risks of deep well mining in the eastern mining areas were analyzed,including the threats of gas disasters,dynamic geological disasters,deep high-pressure water hazards,and deep mine heat disasters to deep mining.Taking Kongzhuang Coal Mine of Shanghai Datun Energy Co.,Ltd.(hereinafter referred to as“Kongzhuang Coal Mine”)as the research subject,a list of potential risks affecting deep well mining in the mine was compiled,a comprehensive,well-established,and valuable deep well disaster prevention and control system was established.Through deep resources estimation,mining technology level study,SWOT analysis and other methods,a comprehensive assessment on the mining technology and economic viability of deep coal resources was conducted.The study results indicate that the mining technology and economic feasibility of the deep coal resources in Kongzhuang Coal Mine are both viable,the research findings are of significant value for enhancing the self-sufficiency of coal resources in the eastern mining areas,extending the service life of mines,and ensuring regional economic stability.
