走向高抽巷抽采在阳泉三矿的应用

Application of Strike High-bleeding Roadway for Drawing Out Gas in Yangquan NO.3 Cola

为了解决阳泉三矿K8206工作面煤矿瓦斯超限的问题,对该矿的走向高抽巷抽采技术进行研究。介绍了阳泉三矿K8206工作面概况,采用安全学基本原理及方法,对倾斜高抽巷的布置参数进行了分析,得出了走向高抽巷的布置层位为7~20倍采高层位、距回风巷水平投影距离为30-60mm。得出了该技术的优缺点及适用条件,为工作面的安全生产提供了技术保障,同时为该技术在其它高瓦斯矿的推广应用提供了技术支持。

The technology of strike high-bleeding roadway has been researched to solve the problem of gas over-limit of K8206 mining face in Yangquan NO.3 Coal Mine.In this paper,the parameters of high dip tunnel are analyzed by application of basic principle and methodoloty of safety according to conditions of K8206 mining face in Yangquan NO.3 Coal Mine.Then a conclusion is drawn that the strike high-bleeding roadway layout horizon should be 7 to 10 times of mining height,and should be 30 to 60 meters away from the projection of roadway.The research result indicates that application of this technology not only endures safe production of mining face,but also provides technical support for promotion of this technology in other high gas mines.
