摘要:
导水裂隙带高度是水体下安全采煤的主要依据,本文通过数值计算、相似材料模拟、规程预测和工程类比等方法,对高头窑煤矿水多湖川和大哈他土沟河下浅埋煤层开采时导水裂隙带高度进行了预测研究,结果表明:几种方法预测结果有一定的误差,综合工程类比结果,高头窑煤矿水多湖川和大哈他土沟下采煤时裂采比定为15。由于高头窑煤矿2-3煤层上覆基岩段厚度较薄,根据三下开采规程,煤层开采需要进行安全限采控制,采高h≤H/19,以达到控制导水裂隙带高度的目的,实现河下采煤的安全开采。
Abstract:
The height of water conducted fissure is the main basis for coal mining under water. In this paper, using the methods of the procedures forecast, numerical simulation, equivalent material simulation and engineering analogy, the height of water conducted fissue was analyzed for shallow buried coal seam under the rivers Shuiduohuchuan and Dahatatugou in Gaotouyao Coal Mine. The results showed that there was an error for these forcasting results, and combined with engineering analogy, the ratio of the height of the fractured zone to the mining height is 15 under the rivers Shuiduohuchuan and Dahatatugou. Because the overlying strata on 2-3 coal seam is thin in Gaotouyao Coal Mine, according to coal mining regulations,the mining height must be controled, , in order to reach the purpose of controling the height of water conducted fissure and achieve the safety mining under the rivers.
