摘要
在矿山井下事故发生后的矿工自救中,设置避难硐室是十分必要的。供氧系统是避难硐室内避难人员生存的重要保障,避难硐室具有容载人数多、空间相对较大的特点。针对国内避难硐室采用的地面钻孔供氧、压风供氧、压缩气瓶供氧、化学氧供氧等供氧方式进行了研究,分别通过基本供风量、供氧量等参数的理论计算方法,密闭空间模拟试验的方法来对几种供氧方式进行比较,最终确定避难硐室设置多种供氧方式的必要性,为今后避难硐室供氧系统的构建奠定基础。
It is very necessary to set up the refuge haven in the underground mine when the accident occurred and then the miners help themselves. The oxygen system is an important guarantee for the survival of survivors in refuge haven. Refuge chamber has a large capacity and a relatively large space. In the domestic, four kinds of oxygen sup- plying mode have been used in refuge haven, such as ground drilling for oxygen, air pressure for oxygen, com- pressed gas cylinders for oxygen and chemical oxygen. The parameters of the basic air volume and the amount of ox- ygen supplying were calculated, in addition, the confined space simulation test method was conducted in order to compare several oxygen supplying mode. Ultimately it showed that it is necessary to set a variety of oxygen supply way in refuge haven, and it lays the foundation for the research and development of refuge haven oxygen supply sys- tem in the future.
