通过对煤岩体在一定初应力和一定频率下的激振作用,使煤体致生裂隙进而改变煤岩体的力学性能.为振动法致生煤体裂隙防治冲击地压理论提供实验依据.
Through the excitation of the coal and rock mass under a certain initial stress and a certain frequency, the induced fracture of the coal mass changes the mechanical properties of the coal and rock mass, which provides an experimental basis for the theory of the rockburst of the induced coal by vibration method.
