摘要
针对矿井小断层发育复杂、切割煤层、影响采煤效率、生产安全等问题,以华恒矿11、13、15煤层小断层资料为依托,通过系统定量分析断层统计学特征,揭示了华恒井田小断层发育特征,在此基础上,利用散点图研究影响因素之间相关性,确定延展长度主要影响因素是断层落差和断层倾角,利用多元线性回归分析法,建立了小断层预测模型,通过实际数据检验,论证模型的可靠性,对煤层开采具有一定指导意义。
Problems against mining safty and efficiency which are caused by small faults happen frequently. Based on small faults data from No.11, 13, 15 coal seam, the paper studied the statistical characteristics of these faults and found their development rules. Then the correlations among factors were studied by scatter diagram. It turns out that the extended length of faults is related to corresponding fault factors, fault dip and fault throw. A prediction model based on multiple linear regression is built. The dependability of the model is examined by operational data. The model is of some significance for mining.
