Changping Mine Gas Extraction Technologies Feasibility Analysis
With the mining level increasing, the gas becomes a prominent problem.The gas from coal in the coal seam with high gas pumping out, will shift to a low gas coal, make coal mining in a safe state, is effective to control the gas accident and the fundamental way to.This article through to the Changping Mine 3＃ seam gas characteristic analysis, proposed the protective layer mining technology and comprehensive gas control technique for the extraction of lower protective seam, gas migration are analyzed and the pressure relief gas drainage method the selection is made, the lower protective layer mining at the same time, take the floor roadway in bed borehole mining method, local Outburst - prevention measures of gas drainage by high level borehole, extraction method, finally to Changping Coal Mine Safety and high efficiency production to provide security.
