陕北榆神矿区薄基岩、浅埋煤层条件下开采引起的萨拉乌苏组含水层大量破坏并导致生态环境失衡。理论和实践证明,这种裂隙损害在一定程度上受到了开采方法的影响。因此,基于协调减损原理研究浅埋煤层不同开采方法对裂隙发育的影响是解决这一问题的又一途径。以陕北榆神矿区王家沟煤矿1301、1302、1303综采工作面为例,应用协调开采方法有效的降低了导水裂隙的发育高度。
The thin-bedded rock in Yushen mining area of northern Shaanxi and the destruction of the aquifer in the Sara Wusu Formation caused by the mining under the conditions of shallow coal seams have caused a great deal of ecological imbalance. Theory and practice have proved that this kind of fissure damage is affected to some extent by the mining method. Therefore, studying the influence of different mining methods of shallow coal seam on fracture development based on the principle of coordinated derogation is another way to solve this problem. Taking the 1301, 1302 and 1303 fully mechanized face of Wangjiagou Coal Mine in Yushen Mining Area of Northern Shaanxi Province as an example, the coordinated mining method effectively reduces the development height of water-conducting fractures.
