沂源韩旺铁矿上河矿段构造及水文工程地质探新

山东省沂源县韩旺铁矿现在正处于露天开采阶段,随着生产需要,需要转入地下开采。由于原来的勘探成果难以满足地下开采的设计需要,在原来的勘探成果上采取加密勘探,进一步查明F1构造断裂带及相应的水文工程地质条件。经查明该区水文地质条件中等;工程地质条件简单;F1断层带宽50~60 m,大部分糜棱岩化,虽然从采矿区域的尾部穿过,但通过参考初步设计,该断层对地下水平开采巷道影响不大。

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.
