在综合机械化采煤过程中,准确地查明采掘前方和采煤工作面的地质构造,有着十分重要的意义.七十年代以来,一些主要产煤国家相继开展了矿井小构造的各种探测工作,获得了较大的进展.其中最受关注的是矿井地震槽波法.有关槽波在层状介质中的传播理论,国外已有不少专著论述.但是,迄今为止地震槽波法在实际中的应用,仍存在不少困难.其原因除了对探测仪器需要防爆等特殊要求外,还在于对槽波的形成、传播特性尚未完
In the process of mechanized coal mining, it is of great significance to accurately identify the geological structure of the mining front and the coal mining face.In the 1970s, some major coal-producing countries successively carried out various exploration work for small structures of mines , The great progress has been made.Most of them are most concerned about mine seismotectonic wave method.For the theory of wave propagation in layered media, many monographs have been discussed abroad.However, In the application, there are still many difficulties.The reason for the probe in addition to the need for explosion-proof and other special requirements, but also lies in the formation of wave, the propagation characteristics have not yet completed
