地下工程震波技术与应用

Technique and application of shock w ave in underground project

激发的震波在工程岩土体中传播,检测其波动力学参数,来测试岩土体的工程力学性质。原位震波波速测试技术可以对井巷的岩体模量、支护选型、围岩性质进行检测;利用地震勘探、面波勘探方法可以对矿层厚度、超前探测等方面进行有效检测;震波CT、导波勘探等探测方法对于采面内的地质异常探测有较好的针对性;通过声发射检测技术可以解决地下工程安全问题。实际应用说明,震波探测技术从地下工程的开拓掘进、采场形成到采后管理等过程中有着广泛的应用前景。一些技术已作为地下工程中的日常工作加以应用,但进一步的生产应用还需深入研究。

The wave' s dynamics parameters are detected t o test rock' s and soil' s body engineering mechanics properties through wave' s transmitting in rock' s and soil' s body.Rock body module,face timbering type of roadways and wall rock pro perties are inspected by original location shoc k wave velocity testing.Ore bed thic kness and advance detection are done efficiently using seismic exploration or surface wave methods.Shock CT and guide wave expl oration have good pertinency to insp ect geophysic ab-normity in exploiting face.And acou stic emission can resolve undergrou nd engineer safety problems.Lots of application in fact showed that shock wave exploration t echnology would have wide prospect f rom exploition of underground engin eer and stope forming to management after mining.Though some technologies have been u sed as routine in underground project,farther produc-ing research still must be done.
