中文摘要：

现有的煤矿井下避难硐室设计只能为紧急避险人员提供一个独立的生存环境却不能使井下避险人员迅速升井，从而彻底脱离危险环境。井下发生瓦斯、煤尘爆炸或火灾事故后有毒、有害气体迅速蔓延，并有随时发生二次灾害的可能，此时地面营救人员下井施救可能会产生非必要的伤亡。针对这个问题，提出了避难硐室的钻孔逃生模式，并在中煤平朔集团井工二矿得到了成功应用。钻孔逃生模式既可为紧急避险人员提供基本生存保障，又可经由逃生钻孔将紧急避险人员送至地面彻底摆脱危险环境，为现有避难硐室设计提供了新的参考。

英文摘要：

The available design of the refuge chamber in underground mine would only provide an independent survival environment to the emergency refuge personnel. The independent environment could not allow the refuge personnel in the underground mine quickly up to the mine surface ground and could not completely be out of the danger environment. After a gas explosion, coal dust explosion or fire accident occurred, a poison and harmful gas would be rapidly spread, a secondary disaster might be occurred at any time and the surface rescue personnel in the underground for the mine rescue might be unnecessarily injured and died. According to the problem, a borehole escape mode of the refuge chamber was provided and wad successfully applied to No. 2 Mine, China Coal Pingshuo Group. The borehole escape mode could not only provide a basis survival protection to the emergency refuge personnel, but also could send the emergency refuge personnel to the surface ground to completely put an end to the danger environment with the escape borehole and could provide a new references to the design of the available refuge chamber.
