煤矿在开采过程中通常会伴随多种灾害事故的发生,如瓦斯爆炸、煤尘爆炸、煤与瓦斯突出、火灾、透水、顶板冒落等。在这些事故中,瓦斯爆炸发生的频率最高,造成的损失也最大。根据国家煤监局年度事故统计,煤矿发生一次性死亡10人以上的重大事故中,绝大多数是瓦斯爆炸事故,约占重大事故总数的70%左右。瓦斯是煤矿安全的极大威胁者,分析探讨煤矿瓦斯事故发生的原因,研究制定煤矿瓦斯防治对策,对预防同类事故的发生具有十分重要的意义。
Coal mines are usually accompanied by various disasters during the mining process, such as gas explosions, coal dust explosions, coal and gas outbursts, fires, water seepage and roof caving. In these accidents, gas explosion occurred the highest frequency, causing the greatest loss. According to the annual statistics of the State Administration of Coal Mine Administration, among the major accidents with over 10 deaths in coal mines, the vast majority are gas explosion accidents, accounting for about 70% of the total number of major accidents. Gas is a great threat to the safety of coal mines. It is of great significance to analyze and discuss the causes of gas accidents in coal mines and to study and formulate gas prevention and control measures for coal mines to prevent similar accidents.
