断层滑移区煤与瓦斯突出防控技术研究

Research on Coal and Gas Outburst Prevention and Control Technology in Fault Slip Zone

为了提高大平煤矿断层滑移区煤与瓦斯突出防治技术措施,以吴庄逆断层构造为研究对象,根据工程现场实际情况,通过现场测试、理论分析与数值模拟相结合的方法,系统研究采动影响下断层滑移诱导突出过程中断层滑移规律、断层及相关煤层的应力分布及瓦斯运移动态特征和突出的动态机制,结果表明多因素与煤与瓦斯突出灾害之间的因果关系,并在此基础上对现有防控措施进行优化,从而增强了矿井瓦斯防治能力。

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.
