摘 要:通过求出西部煤矿地质开采条件下岩层移动规律的各个参数(移动角、边界角、断裂角、最大下沉角),确定各种移动变形值及其部分特征,对通常使用的计算最大下沉值的经验公式提出了改进,并通过实测资料验算证明,本文提出的一种精度高且符合实际的新计算方法,合理地解决了相关问题。By calculating various parameter of rock strata displacement (displacement angle, boundary angle, fractured angle, angle of maximum subsidence) under the geological and mining characteristics of western coal mines, the paper determines various movement and deformation values and their partial characteristics, shortcomings and disadvantages of empirical formula for maximum sinking value that mostly used are put for- ward, after the improvement and the experimental measurements had proved, the paper presents a new kind of calculation method with high-precision and accord with actual which can solve related problems reasonably.
