摘要
随着煤炭行业的飞速发展,以往的掘进速度远远满足不了现代化矿井的采掘平衡。龙固煤矿七五开拓大巷快速掘进方法的试验成功,为解决该问题提供了很好的途径。
With the rapid development of the coal industry, the driving speed in the past can＇t meet the balance of mining and tunneling in the modem extraction. The success of rapid driving in No.75 opening tunnel in Longgu Coal Mine, provided a good way for solving the problem.
