摘　　要：为了分析兴隆庄煤矿主采煤层可注水性,采集了兴隆庄煤矿3#煤层煤样,进行了原始含水率、自然吸水率、孔隙率及坚固性系数进行实验室测定。结果表明,3#煤层煤样原始含水率在2.8~3.0%之间,自然吸水率平均为3.24%左右,吸水3~4d左右达到饱和状态,煤样孔隙率在4%~6%之间,煤样坚固性系数平均为2.4左右,3#煤层各项指标均符合煤层注水可注性鉴定标准。因此,兴隆庄煤矿适合采用煤层注水防治矿井灾害。In order to analysis the lfoodability of primary mineable coal bed in Xinglong coal mine, collected coal samples of 3# coal seam and conducted laboratory measurement about its original moisture content, natural water absorption, porosity and consistent coefficient. The results show that original moisture content of 3# coal seam between 2.8%to 3.0%, natural water absorption averaged around 3.24%and reached saturation after 3 to 4 days, the porosity of coal samples between 4%to 6%, consistent coefifcient around 2.4 and all indicators of 3# coal seam are in line with the indentiifcation standard about the lfoodability of coal seam. Therefore, Xinglong mine is suitable of prevent mine disaster by water injection.
