摘　　要：培丰勘探区重新进行地质勘探施工已多年,重新施工钻孔26个。发现该区东部发育有呈"楔状叠瓦扇"走向近南北的推覆构造。推覆构造地表有槽硐探控制、地下有7个钻孔控制。在老地层推覆体下找到了童子岩组(P_1t)煤系。对培丰勘探医东部构造形态认识方面有了新的具有规律性的认识,这一成果对龙永煤田今后类似矿区勘探具有重要指导意义。The exploration area had been re construction for many years,and the number of construction drilling is 26.It was found that the eastern part of this area is a thrust nappe structure with a ＂wedge shaped fold tile fan＂ toward the South and North.The surface has costeaning and exploratory tunneling control,the underground has 7 drilling hole control.Under the old strata,the boy rock group（P1t）measures were found.There is a new Realization on the structural form of the eastern part of Peifeng coal District.The results have important guidance to the similar mining area of Longyong Coalfield Explorations.
