【摘要】：针对水文地质条件复杂矿井其充水水源和导水通道难以确定,单一的防治水技术无法取得满意的防治水效果的问题进行研究,提出了通过地面物探、现场踏勘、地表水流量监测及水文、地质、气象资料综合分析等多种手段探查矿井充水水源及导水通道的方法,并据此研究矿井水害综合防治技术。以水文地质条件复杂的平煤股份七矿为例,用综合探查方法查明了七矿的充水水源和导水通道,并据此制定了地表河道局部硬化和导水通道地面注浆截流的综合治水方案。初步实施后,评估表明七矿充水水源和导水通道探查准确,所采取的综合防治水措施效果良好。故综合探测方法可准确确定水文地质条件复杂矿井的充水水源及导水通道,综合防治水措施的防治水效果良好。
[Abstract]:In view of the difficulty of determining the source of water filling and the channel of water diversion in mines with complex hydrogeological conditions, and the problem that a single water control technology can not achieve satisfactory results of water control, the paper puts forward that surface geophysical exploration and field exploration are carried out. The monitoring of surface water flow and the comprehensive analysis of hydrology, geology and meteorological data are used to probe into the methods of mine water filling source and water diversion channel, and the comprehensive prevention and control technology of mine water hazard is studied accordingly. Taking Shaheqi Coal Mine with complex hydrogeological conditions as an example, the water filling water source and water diversion channel are found out by comprehensive exploration method. Based on this, a comprehensive water control scheme for local hardening of surface river channel and surface grouting closure of diversion channel is established. After preliminary implementation, the evaluation shows that the water source and channel of water diversion in No.7 Mine are accurate, and the comprehensive water control measures taken are effective. Therefore, the comprehensive detection method can accurately determine the water source and diversion channel of the mine with complex hydrogeological conditions, and the comprehensive prevention and control measures have a good effect on the prevention and treatment of water.
