摘要
基于断裂构造几何及分布特征研究,提出断层影响因子概念,研究确定了采用断层影响因子进行煤层底板突水风险划分的方法。通过现场工程实践验证,该方法研究成果与实测资料吻合程度较高,取得了良好的安全和经济效益。
Based on the geometry and distribution characteristics of the fault structure, the concept of fault influence factors is proposed, and the method of adopting the fault influence fac- tors to classify the water bursting risks in coal seam floor is determined. The situ engineering practice verifies the research results of the method have highly coincided with the measured data, and gained good safety and economic benefits.
