为了提高赵庄矿在特殊地质条件下煤与瓦斯突出防治的针对性，通过理论分析和数学统计研究了赵庄矿断层构造和煤与瓦斯突出的关系，对巷道过断层构造期间反映煤层突出危险性的钻屑瓦斯解吸指标、瓦斯涌出量、瓦斯含量、施工动力现象的变化规律分别进行了分析，结果表明：赵庄矿地质构造以落差小于5m的正断层为主，一般距地质构造带越近，瓦斯赋存越异常、构造应力越集中；断层对煤与瓦斯突出的控制范围在30 m左右。

In this paper, study was carried out on the relationship between fault structure and coal and gas outburst in Zhaozhuang Coal Mine through theoretical analysis and mathematical statistics, and analysis was made on the drilling cuttings gas desorption index, the amount of gas emission, gas content and the change law of the dynamic phenomenon in construction in the roadway driving process through fault in order to improve the prevention and control of coal and gas outburst in this mine under the special geological conditions. The research results showed that the faults in Zhaozhuang Mine were mainly the normal faults with the throw less than 5 m, the more close to the geologic structural zone, the more abnormal the gas occurrence and the more concentrated the structural stress;the control scope of the fault to the coal and gas outburst was in about 30 m.
