摘　　要：针对我国煤矿现有紧急避险疏散体系不能完全满足逃生需求的实际情况,指出当前避灾硐室存在选址不合理、逃生效率低下等问题。通过在避灾路线上建立多个备选避灾硐室,利用最短路径法求取巷道最短当量长度,建立了煤矿采场发生爆炸时以时间为主要参数的人员疏散模型,并得出评价人员逃生效率的安全疏散系数K=tTASE/(tR+tA+D/V),探讨了避灾硐室位置合理的布置范围,为救援活动提供了充足的准备时间,为人员紧急疏散提供了有效参考。Aiming at the actual situation that the existing emergency safety evacuation system can not fully meet the demand of escape.We pointed out that some unreasonable locations for mine refuge chamber and inefficient evacuations still existed in coal mines. Multiple alternative chambers were built on routes for avoiding disaster and the shortest equivalent length was attained by the shortest path method. The main parameter of time was taken to establish an evacuation model for mine stope. Then we concluded the safety coefficient K = tTASE/（ tR＋ tA＋ D / V） and discussed the reasonable arrangement for chambers. It shows that the evacuation model provides effective reference for evacuation and ample time to prepare for the rescue activities.
