Study and Application of the Technology of Progressive and Large Diameter Buried Drainage Pipe by Crossing-Hole
The purpose of the paper is to solve gas limitation of the upper corner of working face of the protective seam. According to the actual situation of the 12nd Mine of the Ping Dingshan Mining Group Corporation (hereinafter referred to 12nd Mine), the technology of progressive and large diameter buried drainage pipe by crossing-hole was put forward, by the way of numerical simulation and field tests. The best reasonable distance and drainage hole diameter of the buried drainage pipe was obtained through the FLUENT simulation, and in accordance with the actual site, the protective seam Ji 14-31010 and Ji 15-31010 have implemented the buried drainage pipe in the site layout, and effective analysis was carried out. Its known by the actual performance that the technology can solve the problem of the gas limitation in the upper corner effectively.
