煤矿通风瓦斯安全分区控制体会

Experience in Zoning Control of Ventilation and Gas Safety in Coal Mine

瓦斯是井下有毒有害气体的总称。在煤矿这种有毒有害气体以甲烷为主。所以,狭义的瓦斯往往泛指甲烷。一般来说,如果瓦斯在空气中的含量大,会降低空气中的氧含量,人员呼吸后会因缺氧而发生窒息事故。如果空气中瓦斯含量在5%-16%之间;氧含量超过12%;遇到高温热源则会发生瓦斯爆炸。本文重点分析煤矿通风瓦斯气体安全分区控制策略,结合当下煤矿通风瓦斯气体安全分区控制的必要性,从动态管控煤矿通风数据、动态管控煤矿瓦斯气体数据、动态管控煤矿安全信息监控数据、动态管控日常资料数据这几点进行深入探索,其目的在于保障煤矿安全,减小对煤矿开采人员生命的威胁。

Gas is the general name of poisonous and harmful gas in underground mine.In coal mine,methane is the main toxic and harmful gas.Therefore,gas in a narrow sense often refers to methane.Generally speaking,if the gas content in the air is large,it will reduce the oxygen content in the air,and people will suffocate due to lack of oxygen after breathing.If the gas content in the air is between 5%-16%;oxygen content exceeds 12%;gas explosion will occur in case of high temperature heat source.This paper focuses on the analysis of zoning control strategy of coal mine ventilation gas safety.Combined with the necessity of zoning control of coal mine ventilation gas safety at present,it makes in-depth exploration from dynamic control of coal mine ventilation data,dynamic control of coal mine gas data,dynamic control of coal mine safety information monitoring data and dynamic control of daily data,aiming at ensuring coal mine safety and reducing the threat to the lives of coal miners.
