【摘要】：近年来,深部开采安全机理与灾害防控领域已取得一定的研究成果,但基于现行理论与技术还难以全面解决未来深部采矿过程面临的防灾减灾问题,至今尚未建立起完善的深部开采灾变与防控研究体系.本文开展了对深部开采灾害研究领域的文献调研和问题探讨,总结有关深部地应力场测量与分布规律、深部岩体力学与耦合损伤机理、深部动力灾害机理与预报、深部突水灾害机理与预警以及深部开采围岩变形机理与防控等方面的研究成果,进而分析当前研究的不足,凝练出深部开采诱发灾害研究领域亟待解决的关键问题,并就未来超深开采灾害研究态势予以分析.
[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.
