新疆焦煤集团1890煤矿在生产中受上隅角瓦斯超限的影响很大,根据1890煤矿6#煤层的实际情况,结合高位钻孔抽放卸压瓦斯的技术原理,利用COMSOL Multiphysics软件模拟和经验公式,确定了适合16122-1工作面高位钻孔的终孔点高度、钻场间距、钻孔抽放半径、钻孔控制范围等设计参数,解决了回采工作面上隅角瓦斯超限的难题。
According to the actual situation of No.6 seam in 1890 coal mine, combined with the technical principle of high pressure drilling and releasing pressure relief gas, the 1890 coal mine of Xinjiang Coking Coal Group is greatly influenced by gas overrun in the upper corner. COMSOL Multiphysics software is used to simulate and experience Formula, the design parameters such as the height of final hole, the distance of drilling field, the radius of drilling holes and the control range of drilling are determined, which are suitable for the high position drilling of 16122-1 face, which solves the problem of gas overrun on the upper corner of mining face .
