摘要

韦家沟煤矿目前已进入-320m深部开采水平,掘进工作面半煤巷施工过程中时遇瓦斯超限情况发生,特别是-320m水平北一采区南翼,半煤岩巷放炮瓦斯涌出量大,严重威胁矿井安全生产,经浅眼松动爆破技术及改变掏槽眼布置的应用,对减少瓦斯瞬间涌出量、控制瓦斯超限情况起到了很好的效果。
        Weijiagou Coal Mine has entered the level of-320m deep mining at present. During the construction of semi-coal roadway in heading face, gas exceeding the limit often occurs. Especially in the south wing of North-first mining area at-320m level, gas emission from semi-coal and rock roadway is large, which seriously threatens the safety of mine production. Through shallow-hole loosening blasting technology and changing the cutting hole. The application of layout has played a very good role in reducing instantaneous gas emission and controlling gas exceeding the limit.
