摘要
为了客观分析立井井筒地面预注浆效果,提出用压水试验计算含水层渗透系数及井筒剩余涌水量的方法,取代常规的抽水试验法。通过调节压水流量实现了多级压水试验,从而更准确地计算出含水层渗透系数及井筒剩余涌水量。
In order to objectively analyze the surface pre-grouting results of the mine shaft sinking, the paper provided to have the pressurized water test to calculate the penetration parameters of the aquifer and the residue water flow method of the mine shaft to replace the conventional water pumping test method. With the adjustment of the pressurized water flow, the multi stage pressurized water tests ware realized. Therefore the penetration parameters of the aquifer and the residue water flow of the mine shaft Could be more accurately calculated.
