摘　　要：突泥、突水防治是矿区深部开采面临的首要难题,而查明矿区水文和工程地质特征是突泥、突水防治的关键。本文以马坑铁矿东区4#、2#矿块为研究对象,采用井下瞬变电磁物探和钻探工程相结合的方法有针对性地对矿块水文和工程地质特征进行了研究分析,并提出了相应防治对策,为采矿设计提供了指导依据。The prevention and control of mud and water inrush is the primary problem faced by deep mining in the mining area,and the key of it is to find out the hydrological and engineering geological characteristics of the mining area.Taking the No.4 and No.2 ore blocks in the east area of Makeng Iron Mine as the research object,this paper studied and analyzed the hydrological and engineering geological characteristics of the ore blocks by using the method of underground transient electromagnetic geophysical exploration and drilling engineering,and put forward the corresponding prevention countermeasures,which provides the guidance for mining design.
