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