Abstract: Due to the low explorationextent in Jingfang Mining Area of Changzhi and the potential area of the coal bed methane exploration and development in Qin shui Basin, the 3D seismic technology method was applied to master the distribution laws of the less than 5 m small fault, sink hole and other structures developed in N 0.3 main mining seam in the mining area.There were 12 normal faults and 1 reverse fault with a strike from east to west were identified in the meddle and north part of t he study are and several sink holes were identified in the south part of the study area.In combination with the seismic attribute and the borehole logging parameters, in comparison with the coherency, the mean reflection strength, there were four seismic attributes of the mean reflection intensity, the max wave peak, the mean square ro ot and instantaneous frequency collected.The seam thickness, gas content and porosity development law was quantitatively analyzed.With the comprehensive analysis on the geological structure and reservoir properties, the enriched zone and the favorable development zone of the coal bed methane were verified at the middle part of t he study area.
