【摘要】：近年來,深部開采安全機理與災害防控領域已取得一定的研究成果,但基于現(xiàn)行理論與技術還難以全面解決未來深部采礦過程面臨的防災減災問題,至今尚未建立起完善的深部開采災變與防控研究體系.本文開展了對深部開采災害研究領域的文獻調研和問題探討,總結有關深部地應力場測量與分布規(guī)律、深部巖體力學與耦合損傷機理、深部動力災害機理與預報、深部突水災害機理與預警以及深部開采圍巖變形機理與防控等方面的研究成果,進而分析當前研究的不足,凝練出深部開采誘發(fā)災害研究領域亟待解決的關鍵問題,并就未來超深開采災害研究態(tài)勢予以分析.
[Abstract]:In recent years, some achievements have been made in the field of safety mechanism and disaster prevention and control of deep mining, but it is difficult to solve the problem of disaster prevention and mitigation in the process of deep mining in the future based on the current theory and technology. Up to now, there has not been a perfect research system of disaster prevention and control in deep mining. In this paper, literature investigation and problem discussion in the field of deep mining disaster are carried out, and the rules of measurement and distribution of deep ground stress field are summarized. The research results of mechanics and coupling damage mechanism of deep rock mass, mechanism and prediction of deep dynamic disaster, mechanism and early warning of deep water inrush disaster, deformation mechanism and prevention and control of surrounding rock in deep mining, etc. The key problems to be solved in the field of deep mining induced disasters are condensed, and the future research situation of ultra deep mining disasters is analyzed.
