在分析我国煤矿井下安全开采状况,可能发生的灾害事故类型及特点、人员分布、避险需求等因素的基础上,探讨煤矿井下紧急避险系统的设计原则,确定避险设施的类型,设计建设了"永久避难硐室﹢临时避难硐室﹢过渡站+安全绳"的井下硐室紧急避险系统。该系统具有投资少,安全可靠,适合于我国煤矿井下作业人员多等特点,满足突发紧急情况下矿工安全避险需要。

Based on the analysis on the safety mining status of the underground coal mine in China, the type and features of the disaster accidents possibly occurr ed, the personnel distribution, the refuge requirements and other factors, the design principle of the underground mine emergency refuge system was discussed, the ref uge facility types were determined, an underground mine chamber emergency refuge system with permanent refuge chamber + temporary+transition station+safe rope was designed and constructed.The system with a large space, less investment, safety and relability would be suitable for the features of many operation personnel in u nderground mine and could meet the safety refuge requirement of the coal miners under the sudden emergency condition.
