在煤炭开采过程中,瓦斯爆炸、煤尘爆炸、煤与瓦斯突出、中毒、窒息、矿井火灾、透水、顶板冒落等多种灾害事故时有发生。在这些事故中尤以瓦斯爆炸造成的损失最大,从每年的事故统计中来看,煤矿发生一次死亡10人以上的特大事故中,绝大多数是由于瓦斯爆炸,约占特大事故总数的70%左右,为此,瓦斯称为煤矿灾害之王。因此,分析瓦斯爆炸原因,制订防治对策,显得特别重要。
In the process of coal mining, gas disasters, coal dust explosion, coal and gas outburst, poisoning, suffocation, mine fires, water seepage, roof caving and other disasters have occurred from time to time. Among these accidents, the gas explosion caused the most damage. According to the annual accident statistics, the overwhelming majority of major accidents with more than 10 deaths in coal mines are caused by gas explosions, accounting for about 70% of the total number of major accidents. Therefore, gas is called the king of coal mine disasters. Therefore, it is particularly important to analyze the causes of gas explosion and make prevention and control measures.
