摘　　要：在深埋工程中,综合利用“△”形布置钻孔解析基岩标志层信息及2孔标志层+岩芯轴夹角信息,结合立体几何可以推算覆盖型基岩单斜构造产状。增加钻孔数量,理论上,可判断区域覆盖型基岩单斜地质构造情况,包括给出合理的区域岩层产状。In the deep-buried project,the occurrence of monoclinic structure of overburden bedrock can be calculated by comprehensive use of“△”-shaped borehole layout to analyze the information of bedrock marker layer and the information of 2-hole marker layer+the angle between core axes.Increasing the number of boreholes can,in theory,judge the monoclinic geological structure of the regional overburden bedrock,including giving the reasonable occurrence of regional rock strata.

关 键 词：标志层 立体几何 岩层产状 地质构造 探矿
