煤与瓦斯突出,是在短时间内(数分钟),从煤壁内部向采掘空间突然喷出大量煤和瓦斯(CO_2、CH_4等)的现象。它能摧毁井巷设施,使风流逆转,使井巷内充满瓦斯和煤粉,造成人员伤亡,给井下生产造成严重灾害。为有效地采取防实措施、确保安全生产,必须做好煤与瓦斯突出危险性的预测工作。预测煤与瓦斯突出(以下简称突出)
Outburst of coal and gas is a phenomenon in which a large amount of coal and gas (CO_2, CH_4, etc.) are suddenly ejected from the inside of the coal wall to the excavation space in a short time (a few minutes). It can destroy well facilities and reverse the wind so that gas and coal are filled in the shaft, causing casualties and causing serious disasters to the underground production. In order to effectively take the prevention measures and ensure the safety in production, the prediction of the danger of coal and gas outburst must be done. Predict coal and gas outburst (hereinafter referred to as outburst)
