Research on Forming Conditions and Enrichment Rules of Coal Bed Methane in West Henan
Abstract
. Based on the analysis of coalfield geological characteristics, forming conditions and distribution law in such coal aggregation areas as Jiaozuo, Pingdingshan and Yima in West Henan, this paper studies macroscopic lithotypes of coal, microcal rock components and features of thermal evolution focusing on air content and influential factors, especially features of thermal evolution and influence of fault development on coal bed methane content. Main physical and chemical properties for coal bed methane, including gas saturation, desorption rate, crustal stress and critical pressure received special attention, including a contrast with main coal bed methane aggregation area in North China. After calculation, coal bed methane content in main blocks exceeds 12000×108m 3 , and thus Pingdingshan and Jiaozuo are ideal mining areas for coal bed methane in the future.
