用崩落法开采厚矿体时,有崩落带出露地表的情况下,岩石和地表产生移动,对其移动过程参数至今尚无可行的计算方法,开采矿床时,根据对崩落带和采空区的测量和仪器观测结果,可直接确定移动过程参数。对岩石和地表移动过程参数仪器观测结果分析证明,随采矿深度增加,在地面出现新裂缝前,发展着平缓移动带,其大小由开采深度、岩体的物理-力学性质和应力应变状 In the process of mining thick ore body with caving method, there is no feasible calculation method for the movement process parameters of rock and surface under the condition that the caving zone is exposed on the ground surface. When mining the ore deposit, Measurement and instrument observations can be directly determine the parameters of the mobile process. Analysis of rock and surface moving process parameters instrumental analysis shows that with the increase of mining depth, a gentle moving zone develops before new cracks appear on the ground, and its size is determined by the mining depth, the physico-mechanical properties of rock mass and the stress-strain
