在煤炭开采过程中,会有多种灾害事故发生,包括瓦斯爆炸、煤尘爆炸、煤与瓦斯突出、透水、着火、顶板冒落等。在这些事故中尤以瓦斯爆炸造成的损失最大,从我国最近几年的煤矿事故统计来看,发生一次死亡10人以上的重特大事故中,绝大多数是由于瓦斯爆炸引起的,约占重特大事故总数的70%左右,为此,瓦斯被称为煤矿灾害之王。实际上,如何有效控制和预防煤矿瓦斯事故是全世界各国面临的共同难题。近年来,南非在传统的常规技术基础上,研发出主
In the process of coal mining, there will be a variety of disasters, including gas explosion, coal dust explosion, coal and gas outburst, water, fire, roof caving and so on. Especially in these accidents, the gas explosion caused the most damage. According to the statistical statistics of coal mine accidents in recent years in our country, the most serious accidents with more than 10 deaths are caused by gas explosion, About 70% of the total number of major accidents, therefore, gas is called the king of coal mine disasters. In fact, how to effectively control and prevent coal mine gas accidents is a common problem faced by all countries in the world. In recent years, South Africa has developed a master based on the traditional conventional technologies
