深部煤岩体高温高围压下力学性质的研究现状与展望

我国煤矿正在逐步进入深部开采阶段，深部煤岩体在高温高压作用下的力学性质和工程响应。与浅部煤岩体在低温低压作用下的力学性质和工程响应有着本质的区别．综合分析了我国目前在深部煤岩体高温高围压下力学性质研究现状，指出了目前深部煤岩体高温高围压下力学性质的研究在实验条件、试验的范围、试验理论基础方面存在的问题，并提出今后深部煤岩体高温高围压下力学性质的研究方向，对当前我国煤矿深部开采具有重要的理论和现实意义．

Research Status of Deep Coal and Rock Mass Mechanic Properties under High Temperature and High Confining Pressure

China coal mines are turning into deep mining step by step. There are essential distinctions of deep coal and rock mass mechanic properties, and engineering response between under high temperature and high confining pressure and low temperature and under low confining pressure. By analysing of deep coal and rock mass mechanic properties under high temperature and high confining pressure. The research problems of deep coals and rock mass mechanic properties under high temperature and high confining pres- sure are pointed out in experimental condition, experimental area and theoretical base. The research area of deep coal and rock mass mechanic properties in the future is put forward, which has great theoretical and practical significance to deep coal mining in China.
