摘要
高峰矿区为国家第 3号重大事故隐患区。从高峰矿 1 0余年来灾难地压与采空区冒落矿震相伴随事实 ,对照我国非煤矿山50年来 3个群次矿区灾难地压及其特点 ,剖析高峰矿地压主控因素特征 ,指出了冒落矿震触发矿区灾难地压机制 ;阐明了矿山工程环境的概化处理 ,矿震与地压的过程耦合 ,采空区与采场的动静耦合数值计算及等效处理等关键问题与发展方向 ;
The Gaofeng mining area is the 3rd greatest accident-hidden zon e in China. Based on the fact that caved mine seisms of mined-out space have fo llowed disasterous ground pressure in Gaofeng mining area for more than 10 years , the authors compare 50 years of disaterous ground pressures of 3 groups of min ing areas in China's non-coal mines and their characteristics, analyse the feat ures of main controlling factors of Gaofeng area's ground pressure and point out the mechanism of caved mine seism inducing mining area's disaster. Key proble ms are explained, including conceptualized disposal of mining engineering environm ents, procedure coupling between mine seism and ground pressure and calculation a nd equivalent processing of dynamic and static coupling values, thus deepening r esearch work on caved mine seisms. The study has laid a solid foundation for sol ving the problem of mining area's disaster arising from ground pressure of China 's non-coal mines.
