The Distribution Law Of Gas Occurrence And The Research Of Coal And Gas Outburst Control Effect In Pingdingshan No.6 Mine

In this paper, the research analyzed mining area and coal mine geological structure distribution and structure of mining area and No.6 mine gas occurrence control. Mine gas geology units of the eastern north west, north of the west to construct especially fold compared with western gas geological unit development is mine gas occurrence is the fundamental causes of the East west high low. No.6 mine is located in west of mine area. gas distribution affected by Guodishan fault, deep gas occurrence is mainly controlled by bedrock thickness. Through Ding 5-6 coal seam outburst of the statistical analysis, obtained the coal and gas outburst distribution: prominent with distribution of, concentrated in floor elevation-350 m ~ of-650 m region.The distribution regularity of coal seam of coal and gas outburst is obtained by statistical analysis data of coal and gas outburst. Then this paper analyzes the gas characteristics, topography, mine construction factors on the impact of coal and gas outburst mine. The influence of gas and small faults on coal and gas outburst is smaller. Topography control the occurrence and distribution of coal and gas outburst.The effect of topography on coal and gas outburs is the control of the stress.The stress distribution rule of mine is concluded Based on the numerical simulation. The change trend of stress and topography are basically identical. The high gradient stress area have obvious relationship with prominent occurred. coal and gas outburst concentrated in the high stress gradient area. Coal and gas outburst danger for deep coal seam has been predicted.
