摘要
以大量的统计、测试分析为基础，从煤层围岩的岩石学特征、剖面组合形式、孔隙结构参数等方面，对韩城北区３号煤层不同围岩的封闭性能进行了研究，确定其封闭类型为良好。
Based on a lot of statistics, tests and analyses,the confining capacities of various enclosing rocks of No.3 coal seam in Northen area of Hangcheng Mining District are studied from the aspects such as petrological properties of coalenclosing rocks,combination forms of sections,structural parameters of pores and so on. It is defined that their confining types are better,providing the basis for the exploration and development of coalbed methane and prediction of mine gas.
