Initial investigations of improvements in in-seam seismic techniques
Over the past decade, in-seam seismic surveys have become a widely used exploration tool within British Coal. In 1985 research commenced with the specific aims of investigating means to extend the range and the applicability of the technique. Topics studied include: (i) alternative source mechanisms likely to provide a more efficient generation of ISS energy; (ii) the orientation of impact sources; (iii) alternative methods for producing a directional explosive source; (iv) the nature of channel wave propagation in coal and its surrounds; (v) the remote location of geophones down long boreholes drilled within the coal seam; (vi) a method of placing an explosive charge down an in-seam borehole.
