Research On Influences And Solutions Of Low Air Pressure Towards Plateau Mine Safety Production

This topic is proposed under the background of the development of western resources. Western part of our country has rich mineral resources, but located at higher altitude and cold region, low air pressure causes the low oxygen pressure that makes bad influence on the development of western mineral resources. The main content of this research is how to eliminate the bad influence. First, identifies the research method, proposes the whole idea of solving the problem of low pressure, including researches on the bad influence that made by plateau low pressure, plateau mine suitable environmental indicators, mine ventilation type, oxygen supply systems, and supporting mine labor organization system. First makes sure the influence of coal mine safety production that low-pressure environment made, then proposes the solving measures, including the following four areas:First identify the environmental indicators that people can do hard physical labor in plateau mine, mainly through the relationship between human physiological indexes, altitude, and oxygen pressure to do qualitative and quantitative research, then determine the altitude around 2700 meters' environmental parameters will satisfy the hard physical labor needs. Second, take positive pressure ventilation to increase underground air pressure. Third, uses oxygen system to increase underground air pressure and oxygen pressure, also did further basic research, including the way to supply oxygen, establish the calculation model of oxygen needs, plan of oxygen supply and oxygen system design, etc. Finally, proposes the labor organization system as a reasonable auxiliary measure for human's adaptation of plateau environment and creating plateau mine production environment.
