摘要
通过矿压观测与分析,研究了工作面收尾期间的上覆岩层运动规律,分析了工作面超前支承压力对回撤巷道稳定性的影响,利用计算机数值软件FLAC^3D对工作面支护情况进行有效地计算、模拟,验证了回撤通道支护优化设计方案的合理性。
Through the observation and analysis of mine pressure, the movement rule of overlying strata during the closing of the mining face was studied, and the influence of the leading bearing pressure on the mining face was analyzed. Effective calculations and simulations using FLAC^3Dhave verified the rationality of the optimal design scheme for the remove gateway support.
