摘要
经对沙坪煤矿18204工作面胶带运输巷顶板破碎带的五种支护方案,进行FLAC3D数值模拟计算,并按周围矿井支护现状调查结果,确定最终优选方案,为现场支护方案的选择和优化提供指导。
There are five supporting schemes for broken roof zones of 18204 working face with belt transportation.Through the FLAC3D numerical simulation on them,the author determines the final optimization scheme on the ground of field investigation to provide guidance for selection and optimization of field supporting.
