采煤工作面前方的地质构造是矿井地质工作者面临的最主要也是最困难的问题之一。随着综采技术的发展,出现了走向长度更大的长壁工作面,更迫切地要求预先查明工作面中的稳伏小构造。为此,人们尝试把各种地球物理方法引进煤矿井下(如地质雷达、无线电坑透等),槽波地震法就是其中之一。六十年代初,西德人克雷首先提出在煤层中可以激发和传输一种特殊的弹性波—槽波,并在井下试验激发和记录到了槽波,证明可以用来探测小断层。此后,在西德和各主要产煤国家竞相研究和试验这种方法,现已取得良好效果,被认为这是最有前途的矿井物 The geological structure ahead of the coal mining face is one of the most important and most difficult problems facing mine geologists. With the development of fully mechanized mining technology, there has been a move to a longwall with a larger strike length, and an even more urgent need to find out in advance a small stable structure in the working face. To this end, people try to introduce a variety of geophysical methods into the coal mine (such as geological radar, radio penetration, etc.), slot wave seismic method is one of them. In the early 1960s, Clay, the West German, first proposed that a special elastic wave-groove wave can be excited and transmitted in the coal seam. Slot waves have been excited and recorded in the downhole test, which can be used to detect small faults. Since then, competing research and testing of this method in West Germany and other major coal-producing countries has yielded good results and is considered to be the most promising mine product
