Technology for Deep Mine Shaft to Open and Pass Through High Outburst,Soft and Low Permeability Seam
Abstract：Based on mastering the gas parameters of each gas outburst seam opening in the new mine auxiliary shaft of Taoyuan Mine,Huaibei Coal Mining,according to the outburst seam opening features in the deep mine shaft,the technology to safe open and pass through outburst seam with pressure flushing boreholes in the mine shaft was provided.According to the high outburst danger and poor permeability of the seam and the gas not easy emission features due to the water in the downward borehole of the mine shaft,a safety seam opening technology with detection,consolidation and pressure flushing borehole was conducted.The practices showed that the new auxiliary mine shaft had a successful opening and passing through No.72 and No.82 outburst seams and had solved the technical difficulties of the mine shaft construction,which could provide the technical references for the mine shaft at home and abroad to safely open outburst seam.
