煤与瓦斯突出是煤矿采掘过程中发生的严重自然灾害之一,它是井下含瓦斯煤体在极短的时间内,从煤壁内部向采掘空间突然喷出大量煤和瓦斯的动力现象。突出物会造成埋人、堵塞巷道、破坏设施等,突出的瓦斯使人窒息或引起瓦斯爆炸,造成严重的人员伤亡和矿井损毁事故。随着矿井开采深度的增加,开采地质条件也日趋复杂,矿井深部开采过程中的突出问题将愈加明显。作为煤与瓦斯突出矿井,如果能够及时采取一些行之有效的防突措施,可以有效避免人员伤亡事故的发生。
Coal and gas outburst is one of the serious natural disasters that occur in the coal mining process. It is a dynamic phenomenon that a large amount of coal and gas are suddenly ejected from the inside of the coal wall to the mining space in a very short period of time. Protrusions can cause people buried, blocked the roadway, destruction of facilities, prominent gas suffocating or cause gas explosion, causing serious casualties and mine damage accident. With the increase of mining depth, the mining geological conditions have also become more and more complicated. The prominent problems in the deep mining process will become more obvious. As coal and gas outburst mine, if it can take timely and effective measures to prevent outbreaks, it can effectively avoid the occurrence of casualties.
