Research On Xiegou Mine’s Determination Of Basic Parameters Of Gas And Treatment Technology

Mine gas disaster is the most important of the coal industry, largest security natural disasters, hasbeen restricting the continuous improvement of production efficiency in various coal mines in China, hasbeen a serious threat to the life safety of the daily life of the production of coal and underground everyworkers. For inclined coal mine, with the increasing depth of mining, resulting in a coal mine gasemission in the rising, proceed from the gas disaster management research to find a suitable to solve theoblique groove comprehensive measures of coal mine gas disaster, and ultimately solve some of the localgas overrun. Including the goaf and the upper corner.Through the determination of coal seam gas pressure, permeability coefficient, gascontcet, coal sample composition and it’s attenuation coefficient, and other basic parameters, theestimated gas reserve of the mine, the sub-source method and use the prediction of gas emission,and then research coal mine gas drainage in the economic and technical feasibility.According tothe mine gas emission at the same time drainage of the coal seam and goaf gas drainage method,and for different regions with different design of the drainage program, the final drainage of theeconomy estimated.In this paper, suitable for inclined coal mine gas control, and comprehensive managementof coal mine gas disaster of the oblique groove, not only the underground mine to have a safeproduction environment, thus improving the efficiency of mine production. In addition, theguiding significance for the further production of the inclined coal mine face.
