摘要
矿井避难硐室在灾变时为矿工提供了隔绝密闭的避难空间,内部正压密闭系统起到了隔绝有毒有害气体的作用。本文对矿井避难硐室正压系统进行研究,确定影响矿井避难硐室正压数值的因素,通过理论计算确定了矿井避难硐室正压值,同时确定了矿井避难硐室的正压维持方式并设计了相应的余压阀。为保证矿井避难硐室正压的实现,对矿井避难硐室密闭系统进行研究,包括建筑密闭和设施密闭。
Mine refuge station can provide the isolated refuge confined space in the disaster,and the internal positive pressure-confined system plays the role of isolating toxic and harmful gases.In this article positive pressure system in mine refuge station was studied,the factors affecting the positive pressure values of mine refuge station were determined.Through theoretical calculations,the positive pressure value of mine refuge station and the way of maintenance positive pressure,were determined and also residual pressure valve was designed.In order to ensure the realization of positive pressure in the refuge station,the confined system of mine refuge station was studied,which include construction airtight and facilities airtight.
