摘要
本文以淮南新集三矿西三采区煤层开采为研究对象,采用非线性大变形FLAC程序,对厚松散层下煤层开采的地表移动变形特征进行了数值模拟。分析了该地质采矿条件下,不同开采方案对地面防汛堤坝的影响,并进一步研究了无煤柱开采工作面距堤坝不同距离时,堤坝的移动变形特征,为煤矿生产和堤坝的稳定加固提供了科学依据。
According to coal mining conditions of Huainan Xinji mining in No. 3 mining district, the movement and deformation characteristics of surface were simulated and analyzed by FLAC with coal mining of thick soil layers . The influences of different mining scheme on dyke of flood were analysed on the condi- tions of geology and mining. And the dyke movement and deformation characteristics of different distance between working face without coal pillar and dyke were further studied. The results provide some scientific references for safely mining and reinforcing the dyke.
