Coal mining in the United Kingdom is mainly by means of highly capital intensive, long wall faces. With such methods it is almost axiomatic that mine planners should have a good knowledge of the stratigraphy of the ground which is about to be mined. All too often this information is unavailable.
Channel wave, or in-seam, seismology offers a method for the advance exploration of coal seams. Recent work in a number of countries has resulted in the development of specialised recording and processing techniques, and the method has been shown to be viable.
In this paper we concentrate on a number of case histories, paying particular emphasis to those predictions that have been verified by mining. In one instance a fault at a range of 500 m has been predicted.
