Abstract
Novelly Nuclear Magnetic Resonance Imaging (NMRI) as an advanced non-damaged measurement technique was introduced into the experimental research of transport of CBM. The home-made triaxial osmoscope made up of nonmagnetic polycarbonate material was designed and developed. The home-made osmoscope which has coal sample placed into the magnetic bore of NMRI equipment, a series of NMRI experiments of coal sample were made including NMRI experiment of the natural coal sample, the NMRI permeability measure experiment of coal sample of saturation water, NMRI experiment of gas driving water and NMRI experiment of water driving gas. In the experiments, the rough coal sample and the pressed coal sample were chosen individually. The processes of the water seepage, gas driving water and water driving gas in the coal sample were real-time, directly, visually measured. The many experimental conclusions with the practical engineering value were achieved for example the leading edge of water driving has inconsistency, the existence of dominance driving pathway was tested and the way almost kept fixed and so on.
