Abstract: With exhausting of shallow coal resources, exploration and development of coal in deep coverage area became the reluctant choice. But, it is very difficult for coal exploration in deep. Therefore, a comprehensive analysis of multi-source information and study on mineralization pattern should be carried out before exploration. During exploration, firstly carries out two-dimensional seismic survey, then analyze various ore-forming elements based on the coal floor contour, finally the drilling and 'trilateral' timely follow-up. On the study of exploration method, the next principle should be followed:modern coal-forming theory as a guide, geological research as basis, advanced technology as a means, from surface to deep, from known to unknown, gradual and orderly conducting every process of exploration. According to a series of information obtained, a series of ore-forming elements should be comprehensively analyzed, then the preparation of report on exploration achievements.
