【Abstract】 Through designing experiments of coal splitting,the splitting microseismic signals in the coal destruction process are monitored.Through combining with the crack developing law in the process of coal splitting,the relationship is analyzed,which is between the microseismic signals in the process of coal splitting and the process of the crack developing.The spectral characteristics of the microseismic signals in the process of coal splitting are also analyzed.更多还原
