【摘要】 采用急倾斜崩落法开采的金属矿山与急倾斜煤矿开采的地表沉陷均属于构造应力作用下的地表移动问题 ,它们与自重应力作用下煤矿地表移动规律的区别在于 :后者同时还受构造应力、矿体产状、覆岩结构、开采与放矿等的影响。指出了考虑上述因素的改化岩移随机介质理论的发展前景 ,这是对俄罗斯、哈萨克斯坦、乌克兰等国用实测经验统计法解决矿山开采工程问题的发展。更多还原

【Abstract】 Two types of mining surface subsidences resulting from steeply pitch caving mining of metallic mines and pitch ming of coal mines are a ground movement by the effect of tectonic stress. This type of ground movement is differential from the mining surface movement of coal mines by the effect of gravity stress. The latter is not only affected by gravity stress, but also by tectonic stress, orebody′s occurrence, cover rock makeup and ore discharging. The authors point out the prospects of the revised theory of random medium of rock movement, which deals with the above factors. This is the development of solving mining engineering problems using empirical statistics of actural measurements in Russia, Kazakstan and Ukraine.更多还原
