采空区探测是工程建筑和煤矿生产中亟待解决的问题。常规物探方法在对落后的“房—柱”式开采技术造成的面积较小、埋深较浅的采空区进行探测时存在漏报或误报的情况。根据采空区的地球物理特征,探讨多道瞬态瑞雷波技术的探测机理,并通过勘探实例阐述了该方法在浅层煤矿采空区探测中的实用性和有效性。
Gob area exploration is an urgent problem to be solved in engineering construction and coal mine production. Conventional geophysical methods are underreporting or false positives when probing for smaller, less deep mined-out areas caused by backward “room-and-column” mining techniques. According to the geophysical characteristics of goaf, the detection mechanism of multichannel transient Rayleigh wave technology is discussed. The feasibility and effectiveness of this method in the exploration of goaf in shallow coal mines are illustrated through exploration examples.
