斜井二次涌水原因分析及注浆治理措施
Hydrogeological analysis and control of groundwater inrush for the second time in an inclined shaft
摘要
Abstract
A groundwater inrush occurred again when excavation came to the pregrouting interval in the auxiliary inclined shaft, which submersed the shaft of the Heilong Coal Mine in Shanxi. The main cause was that the poorness of the fracture stability was formed during the interaction of soft clay and grout in the first grouting process. The method "distributary to relieve pressure then to prevent water inflow" was taken, thus the uncontrollable gushing was changed into controllable gushing and grouting. The borehole was used to examine the effect of the grouting, and the results show that the effect was good. This paper provides references for similar grouting in rock mass which is filled with soft clay.关键词
