摘要
扩建、延深水平矿井水文地质补充勘探,应充分利用矿井已有的地质和水文地质资料,尤其是具有水文地质意义的井下长期涌水点。双柳煤矿太原组灰岩含水层富水性较弱,且埋深较大,在地面施工大口径水文勘探孔工程量大、费用高,且勘探周期长。根据水文地质补勘充分利用郭家山风井涌水长期观测资料,配合适量的小孔径地面观测孔,较好地控制了井田太原组灰岩含水层的地下水流程,取得了较准确的水文地质参数,既节省了勘探费用,又提高了勘探成果的可靠性。
Hydrogeological supplement exploration of expanding and deepening level mine should make full use of existing mine geological and hydrogeological data, especially the underground long -term water point with hydrogeological significance. Shuangliu coal mine of Taiyuan group limestone aquifer water yield property is weak and the buried depth is larger. It will lead to large quantities, high cost and long exploration period of constructing the hydrologic exploration hole of large diameter in the ground. According to the hydrogeological supplement exploration, makes use of air shaft water burst long - term observation data in Guojiashan, cooperates with the moderate small - bore ground observation hole, it better controls the groundwater flow of Taiyuan group limestone aquifer. Obtains the accurate hydrogeological parameters. Saves the exploration cost, and improves the reliability of exploration results
