Analysis on Main Controlling Factors of Coal and Gas Outburst in Liangbei Coal Mine

There is a correlation between the main controlling factor of coal and gas outburst and the choice of sensitive index. Through the comprehensive analysis of coal and gas outburst characteristics over the years, the correlation between mining geology structure and gas content, parametric measurement of coal samples, we determine main controlling factors of coal and gas outburst in Liangbei Coal Mine. According to the correlation, we carry out post-conducted sensitive index investigation and verification in the front of the heading face on-site, which provides the reference for coal and gas outburst prevention and treatment for similar outburst mines.
