震动波主动CT探测原理及应用

Principle and application of vibration wave active CT detection

由于工作面刚形成,为了更好地推进采煤工作面冲击地压防治工作,确定工作面及其交叉巷道内的围岩应力集中状态,通过在工作面一侧布置传感器、一侧布置炮源,使用主机收集放炮信号波形,采用震动波主动CT探测技术对工作面进行应力场反演,划分冲击危险等级及区域,从而对不同危险等级区域采取针对性卸压解危措施。

As the working face has just formed,in order to better promote the prevention and control of rockburst in the coal mining face and determine the stress concentration state of the surrounding rock in the working face and its cross roadway,the sensor and blasting source are arranged on one side of the working face,the host is used to collect the blasting signal waveform,and the vibration wave active CT detection technology is used to inverse the stress field of the working face,to divide the impact risk level and area,so as to take targeted pressure relief measures for different risk level areas.
