The role and mechanism of the shallow hole water flooding in coal seam were analyzed.
分析了煤层浅孔注水的作用与机理,并根据告成矿井田的煤层地质条件,确定了注水参数和注水工艺,使得该矿在煤巷掘进过程中的顶板管理取得了良好效果。
6) dynamical pressure water infusion
动压注水
1.
Through the combined technologies experiment of dynamical pressure water infusion in the coal seam,tunnelling with the pneumatic pick and handpick,U-bar support and I-bar spreader bar support,we have found the ways to solve the problems such as the great pressure,being soon in bad repair,being hard to uphold,and short using cycles of the tunnels in Lugou Coal Mine.
通过利用煤层动压注水、手镐配合风镐掘进、U型钢支架配合工字钢扩杆支护联合技术的实验,找到了解决芦沟煤矿巷道压力大、失修快、难以维护、使用周期短等难题的途径。
