摘要
针对宏岩煤矿一采区 10105 工作面末采影响轨道下山、采区水仓的问题,通过分析明确了异常矿压的显现机理,据此制定了合理、可行的针对性切顶卸压方案,可指导井下施工.
Abstract
In view of the problem of the impact of the first mining area of 10105 working face of Hongyan Coal Mine affecting the downhill track and the water tank in the mining area,the mechanism of abnormal strata behaviors were clarified through analysis,and a reasonable and feasible targeted roof-cutting pressure relief scheme was formulated accordingly,which can guide the underground construction.
