摘要 为对常村煤矿煤层稳定程度进行评价进而指导工程设计和矿山生产,在总结煤矿井田地质特征基础上,对主要可采煤层的稳定性进行了定性和定量评价。山西常村煤矿井田内主要含煤地层为石炭系太原组和二叠系山西组,可采煤层以山西组3#煤层和太原组15-1#、15-3#煤层为主。分析认为煤层的定性和定量稳定性分析显示,3#煤层为不稳定局部可采煤层,15-1#煤层为不稳定局部可采煤层,15-3#煤层为较稳定大部可采煤层。常村煤矿煤层稳定程度总体属简单类型。 In order to evaluate the stability of coal seams in Changcun Coal Mine and guide engineering design and mine production,the stability of the main mineable coal seams was evaluated qualitatively and quantitatively on the basis of summarizing the geological characteristics of coal mine fields.The main coal-bearing strata were Carboniferous Taiyuan group and the Permian Shanxi group,and No.3 coal seam of Shanxi group and No.15-1#and 15-3#coal seam of Taiyuan group were the main mineable seam.The qualitative and quantitative stability analysis of coal seams showed that No.3 coal seam was unstable and locally minable,and No.15-1#coal seam was unstable and locally minable,and No.15-3#coal seam was relatively stable and most minable.The stability of coal seam in Changcun Coal Mine was a simple type on the whole.
