摘要
九龙矿为水文地质条件极复杂、地质条件极复杂型矿井,井田煤层埋藏深、水压高、矿山压力大。15445N工作面为野青工作面,虽经区域治理并实现安全回采,但在工作面回采后期,底板仍出现涌水。针对这一情况,通过探查工作面底板涌水的情况,分析查明了涌水原因,对地面区域治理技术的改进和野青工作面防治水技术对策的研究,有着重要的意义。
Jiulong Mine with extremely complicated hydrogeological conditions and extremely complicated geological conditions, the coal seams deeply buried, with high water pressure and high mining pressure, the working surface of the15445 N was the wild green working face. Although the area was done with safe recovery mining, in the later stage of the working face, there was still water in the floor. In view of this situation, it was of great significance to analyze the situation of water inflow from the floor of the working face, to clarify the cause of water inrush, improve the treatment technology of the ground area and study the water technology countermeasures of the wild green working face.
