Gas Extraction Techniques Based on Gas Geology in Zhengzhou Mining Area

The article analyses gas geological characteristics in Zhengzhou mining area from structure, buried depth, coal thickness and several other factors, especially sliding structure, they have not only controlled coal seam genesis and tectonic coal distribution, made coal seam gas further release and could confine coal seam gas, but also made gas pressure critical value of coal and gas outburst lower, then analyses signs and regularities of gas outburst in the area, and targeted to research on gas extraction techniques, finally, proposed gas control countermeasures, and has effectively promoted safe development in the area.
