Prospecting Coal Bed Methane Resource in Anyang-Hebi Mining Area

There was rich coal bed methane on Anyang Hebi Mining Area.In order to well guide the exploration and development of the coal bed methane and the mine gas disaster control in the area and base on the information of the coalfield exploration and coal bed methane exploration,a systematic discussion were conducted on the geological features of the coal bed methane in the area.With the analysis on the geological structure background,coal reservoir features,coal adsorption features,earth stress features,B1 coal bed methane content and others,the paper provided the distribution features and control factors of the methane contents.Base on the circumstances the paper predicted the coal bed methane content of the B1 seam in this block and evaluated the development potential of the coal bed methane resources.The study results showed that there were high coal bed methane content in B1 seam of the block,high permeability,rich coal bed methane resources,coal bed methane resources up to 113.298 billion m3 and good development potential of the coal bed methane.There were 3 favorable coal bed methane development areas in the block area and the Zhangwu Luenzhang-Luxian-Tongzhi area could be the first selected development area.
