Abstract: The paper took Wangxingzhuang Coal Mine of Henan New Energy Development Co., Ltd. as research background, introduced protective seam mining theory, and investigated gas parameters in the same test site before and after taking protective layer mining measures, including gas content, gas pressure, coal seam permeability coefficient and outburst predictive index. Field test results show that after taking protective layer mining measures, gas pressure and content of the protected layer region reduce significantly, the gas emission amount and outburst predictive index decrease obviously, and seam permeability coefficient increases greatly.
