摘要
通过对张家峁煤矿N14201工作面末采阶段的围岩变形和矿压观测,得到了巷道变形、垛式支架工作阻力及矿压显现规律等数据,为该矿及同类条件矿井4-2煤工作面回撤通道的支护评价和参数优化提供了依据。
Through the observational study of surrounding rock deformation and strata behaviors of N14201 face in Zhangjiamao mine, got the roadway deformation, crib support's working resistance and other strata behavior data, the study provides a basis for 4-2coal face of Zhangjiamao mine and the similar condition dismantling channels' support evaluation and parameter optimization.
