| 摘 要： | 导水裂隙带高度是水下采煤的主要依据,通过相似材料模拟对高头窑煤矿水多湖川河下浅埋煤层开采时导水裂隙带高度进行了研究。结果表明:相似材料试验和"三下"开采规程预测高头窑煤矿煤层开采导水裂隙带高度有一定的差距。随着采高的增加,两者相差越来越大。高头窑煤矿水多湖川采煤时裂采比为15,煤层开采是需要进行采高控制,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 mining under water.In this paper,using the methods of equivalent material simulation,the height of water conducted fissue was analyzed for shallow buried coal mining under the rivers Shuiduohuchuan in Gaotouyao coal mine.The results showed that there was error in water conducted fissure height between regulations predicition and similar material experiment for Gaotouyao coal mining.Along with the increase of mining height,both differ is more and mo... |
