摘要:
在现场调查的基础上,对巷道的表面变形和深部围岩变形规律进行了监测,分析了王洼矿区软岩回采巷道围岩变形与破坏机理。监测表明:煤层开采深度较大,围岩变形情况复杂,因现有的锚网支护条件下围岩不能保持平衡,难进入稳定状态,满足不了该条件下的围岩变形,采用锚棚联合支护后最终进入稳定。原支护主要是没有考虑到软岩全煤巷道裂隙发育,锚固长度对锚固支护的有效性差的特点,采用锚棚联合支护或加长锚固能够有效控制巷道的变形和破坏。
Abstract:
On the fundamental of the investigation in the field, we monitored the deformation law of the surface of the mining entry and the deformation law of the deep rock, and analyzed the mechanism of the rock-mass deformation and destroy of the soft rock mining entry in Wangwa mining area. The monitor indicates that the mining depth of coal seam is comparatively large and the deformation situation of rock-mass is complex. Because the rock-mass can't keep balance on the present anchor and net support condition, it is hard to enter the balance state and can't satisfy the rock-mass deformation on this condition. Ultimately it keeps balance to use anchor and shed supporting. The anchor and net support majorly pays no attention to the feature of the cranny growth of the soft rock coal mining entry and the validity is poor for the regular length to regular support. Using unite support or increasing the regular length can control the deformation and destroy of the mining entry.
