摘　　要： 潘集深部勘查区作为淮南煤田资源接替基地现已进入详查阶段,为了查明山西组煤层赋存特征与工程地质条件,基于对勘查钻孔资料的统计分析,详细分析了1煤和3煤赋存以及夹层岩性、厚度发育特征。结果表明,山西组1煤和3煤区域平均厚度为3.5m;F66断层以北1煤受岩浆侵蚀,不可采范围集中分布,3煤不可采区域在F66断层两侧零星分布;1煤和3煤间夹层岩性以泥岩为主,平均厚度仅为1.25m。在此基础上,进一步探讨了1、3煤顶底板的岩石强度、岩性组成与结构组合工程地质特征,初步划分顶底板岩性组合类型,为深部矿井的设计和建设以及开采地质条件评价提供可靠的地质资料。 As a succeeding resource base in the Huainan coalfield, the Panji coalmine deep part exploration area has now entered into the general exploration stage. To identify coal hosting features and engineering geological condition in the Shanxi Formation, from ex- ploratory borehole data statistics and analysis, coal seam Nos. 1 and 3 hosting, parting lithological and thickness development features have been analyzed in detail. The result has shown that the regional thickness average of coal seam Nos. 1 and 3 is 3.5m; the nonmine- able regions of coal No. 1 are concentrated to the north of fault F66 because of magmatic intrusion ; while the nonmineable regions of coal No. 3 scattered on both sides of fault F66. Lithology of partings in coal seam Nos. 1 and 3 is mainly mudstone ; average thickness only 1.25m. On this basis, rock strength of coal seam roof and floor, lithologic composition and structural grouping engineering geolog- ical features have been further discussed. The preliminary division of roof and floor lithologic composition types has provided reliable
