Research on Coal and Gas Outburst Prevention and Control Technology in Fault Slip Zone
In order to improve the technical measures for preventing coal and gas outbursts in the fault slip zone of Daping Coal Mine,the Wuzhuang reverse fault structure was taken as the research object.Based on the actual situation of the engineering site,the method of combining on-site testing,theoretical analysis,and numerical simulation was used to systematically study the law of fault slip induced outbursts under the influence of mining The stress distribution and dynamic characteristics of gas migration in faults and related coal seams,as well as the dynamic mechanism of outburst,indicate the causal relationship between multiple factors and coal and gas outburst disasters.Based on this,existing prevention and control measures are optimized to enhance the mine's gas prevention and control capabilities.
