条带开采地表运移模拟与实际观测对比分析

Comparative analysis on the numerical simulation and actual observation of surface movement in strip mining

条带开采是一种常用回收三下压煤的有效开采方式,为了确定合理的开采工艺往往采用数值模拟进行研究。为了确定数值模拟的可靠性,结合某矿开采工艺进行数值模拟,同时对条带工作面地表变化进行实际观测对比。结果表明,误差主要由建模过程中对岩层参数简化造成的,但两者误差差距不大,证明数值模拟是一种可靠的研究手段。

Strip nfining is an effective nfining method commonly used to recover ＂three under＂ coal. In order to deternfine a reasonable nfining technology, numerical simulation was used to study, and the surface movements were observed. The com- parison results show that the error is mainly caused by the simplification of rock parameters in the modeling process, but the difference between them is not big, which proves that numerical simulation is a reliable research method.
