Current status and future trends of deep mining safety mechanism and disaster prevention and control
-
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勢予以分析.Abstract: In recent years, there have been a number of developments in deep mining research with respect to safety mechanisms and disaster prevention and control. However, it will be difficult to fully resolve the challenges associated with disaster prevention and reduction based on current theories and technologies, and as yet no sound deep mining research approach regarding cataclysm and its control has been established. This paper reviews the literature and discusses problematic research areas associated with deep mining disasters, including in-situ stress measurement and its distribution law, deep rock mechanics and the coupling damage mechanism, dynamic disaster mechanism and prediction, and the water inrush mechanism and early warning, as well as the surrounding rock deformation mechanism and control technologies. This paper analyzes the deficiencies in existing research and identifies key problems that must be solved in deep-mining-induced disasters. Lastly, this paper indicates future prospects in the study of ultra-deep mining disasters.
