摘要
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。
Xinjiang Coking Coal Group Coal by 1890 a significant impact in the production of top corner gas gauge, according to the actual situation 6#1890 coal Seam, combined with the technical principles relief drainage gas, the use of COMSOL Multiphysics simulation software and experience formula to determine the appropriate 16122-1face high point height drilled the final hole, drilling field spacing, drilling drainage radius, drilling control, such as design parameters, to solve the working Face upper corner gas gauge problem.
