摘要
针对煤层冲击倾向性判别,采用MATLAB数据分析软件编写核主成分分析程序,对试验煤样的冲击能指数、弹性能指数、动态破坏时间、抗压强度以及弹性模量等煤层冲击倾向性指标进行核主成分分析,获取影响煤层冲击倾向性的主成分序列。根据核主成分分析结果,建立煤层冲击倾向性判别模型,为评价煤层冲击倾向性提供依据,对矿山冲击地压预防具有重要意义。
In order to determine the impact tendency of coal seam, the core principal component analysis program was written by MATLAB data analysis software, and the impact energy index, elastic energy index, dynamic failure time, compressive strength and elastic modulus of coal samples were investigated Core principal component analysis, and obtain the main component sequence which affects the impact tendency of coal seam. According to the results of core principal component analysis, the model of coal seam impact tendency is established, which provides the basis for evaluating the impact tendency of coal seam, Which is of great significance to the prevention of rock-burst pressure.
