Abstract: On the basis of geological exploration and CBM parameter well testing data in Niuchang Yigu mining area of Yunnan province, the article discusses the occurrence conditions of the main exploitation target coal seams No.1 and No.5-c, and estimates CBM resource. We suggest that the mine carry out ground drainage test after successful experience underground to achieve coal and CBM comprehensive exploitation and utilization.
