以新庄孜矿56采区为实验对象,对于煤层开采期间面临的瓦斯治理问题,进行了全面的分析,提出了多重开采下向卸压增透抽采瓦斯技术的方法。现场试验考察证实,通过卸压瓦斯抽采技术的运用,不但,成功地消除了56采区煤与瓦斯的突出危险性,而且,对矿井资源的回收有着重大的意义。
Taking the No.55 mining area of Xinzhuangzi Mine as an example, a comprehensive analysis was made of the gas treatment problems faced during the coal seam mining and a method of gas drainage and gas drainage under multiple mining was put forward. The field test confirmed that the application of pressure relief gas drainage technology not only succeeded in eliminating the outstanding danger of coal and gas in the 56 mining area, but also had great significance for the recovery of mine resources.
