Study on Structure and Hydro-geology of Shanghe Section in Hanwang Iron Deposit in Yiyuan County

Hanwang iron deposit in Yiyuan county is mining in the open air now.Accompanying with production demand,it should be mined under ground.But the former exploration achievements can not meet the design demand in mining underground.Thus,crowding exploration should be carried out to gain the hydro-geological conditon of F_1 fault belt.It is proved that its hydro-geological condition is medium,engineering condition is simple,the width of F_1 fault belt is 50~60m,and major rocks are mylonization.Although it crosses end portion of mining region,it can not effect mining laneway.
