Gas Content Characteristics and Its Influence Factors of Coal Seams in Qinan Coal Mine of Suzhou Mining Area,Anhui Province
摘要
Abstract
Based on the practical needs of coalbed methane(CBM)exploration and development,this paper takes the CBM content in Qinan Coal Mine of the Suzhou Mining Area as the research focus.The No.3,No.7 and No.10 coal seams were selected as the specific research subjects.The authors measured the CBM content and conducted an in-depth analysis of the geological influencing factors,with the aim of revealing the enrichment patterns of CBM.Re-sults show that gas contents of the No.3,No.7 and No.10 coal seams range from 1.46 to 16.60 m3/t(average:11.08 m3/t),5.62 to 18.55 m3/t(average:10.79 m3/t)and 2.44 to 21.80 m3/t(average:9.62 m3/t),respec-tively.In terms of burial depth,gas content of the No.3 and No.7 coal seams is positively correlated with buried depth and bedrock thickness respectively,while that of No.10 coal seam has no obvious relationship with above pa-rameters.In terms of surrounding rock properties,the coal seam roof and floor dominated by mudstone are favorable for the preservation of coalbed methane.structurally,the gas content is significantly affected by Wanglou Anticline and Zhangxuewu Syncline,and their gas content tend to increase away from the structure.In addition,due to magma intrusion,the gas content of No.10 coal seam is relatively high in the northeast of the study area.关键词
