掘进面放炮后瓦斯涌出规律及预防爆炸措施

After the Blasting in Tunneling Working Face,Gas Gush Rule and Prevention Explosion Measure

介绍了矿井掘进工作面放炮后在一定条件下构成瓦斯燃烧爆炸的必要条件。根据实际情况,测定瓦斯涌出的总量,分析了瓦斯涌出规律及沼气浓度变化情况,以预防控制因掘进工作面放炮引起的瓦斯爆炸。

Introduces after blasting in the tunneling working face of the mine,under a certain condition,the essential condition of gas combustion and exploding.According to the actual situation,determines the total quantity of gas gush,analyses the rules of gas gush and the situation of the methane density change,in order to prevent the gas explosion which may be caused by the blasting of tunneling working face.
