The evaluation system for coal resources was established and a related software was programmed based on some former achievements and actual situation of the research area. And the evaluating calculation and data processing were also conducted. The result indicates that in the research area, the resource condition of the 3rd lower coal seam falls in the classes of "good" to "middle". In space, the south and the east parts is better than the north and the west parts. And the east part is suitable for the recent and the near future exploitation and the west part for the long dated exploitation. The distribution regularity of geologic structure and the stability of thickness of coal seams should be studied carefully and more exploration project in the west part should be carried out. The above achievements are significant in the exploitation of coal resource in this region. 展开更多
