Experimental investigation of crosshole seismic .

Three crosshole seismic surveying techniques have been investigated using boreholes on opencast coal exploration sites in northern England. The objective has been to determine their potential for locating old mineworkings and small-scale geological structures. The first method was to propagate seam waves between boreholes, with source and receiver at seam level, to check for coal .

Coalbed Methane - an overview | ScienceDirect Topics

During CBM exploration, the saturation absorption belt that has gone through hydrothermal metamorphism and has been sealed by overburden water is the target for medium- to advanced-ranking coals. Low-ranking coal targets must have thick coal beds, good sealing capacity, shallow burial depth, and good porosity and permeability to be considered for exploration.
