山东省济宁铁矿区济宁岩群变质岩水文地质特征

摘要

Jining iron deposit buried in metamorphic rock of Jining group.Its depth is less than 1000m,and geological exploration depth in the past is over 1000m,while exploration this time can reach the depth of 2000m.The hydrogeological exploration holes have been specifically built with the hole depth of 1500m.On these basis,a pumping test has been carried out,hydrogeological parameters have been gained,and hydrogeological characteristics of metamorphic rock in Jining group have been identified primarily.%山东省济宁铁矿埋藏在济宁岩群变质岩中,埋深在1 000m以下,以往地质勘探多在1 000m以上,该次勘探深度达到2 000m,并专门施工了水文地质勘探孔,孔深1 500m,在此基础上进行了抽水试验,求取了水文地质参数,初步查明了济宁岩群变质岩水文地质特征。
