河北省坎上铁矿南矿段矿坑涌水量预测

Kanshang iron ore mine south block section mine water inflow forecasting in Hebei Province

河北省坎上铁矿南矿段位于滦河洪冲积平原水文地质区(Ⅱ)中滦河河漫滩洪冲积孔隙水强富水亚区(Ⅱ2),其铁矿石资源量为1509.0万t,由于铁矿南矿段在前期投入的勘查工作量相对较少,精度较低,而条件较复杂。有必要开展水文地质勘探工作。采用物探、钻探、抽水试验等工作方法,基本查明铁矿南矿段第四系各含水层与基岩裂隙水各含水层的富水性特征及主要水文地质参数,其各含水层间的水力联系,分析判断铁矿南矿段矿区内不存在断层,局部基岩破碎是多期褶皱导致。结合可研报告开采方案,建立铁矿南矿段地质计算模型,采用大井法,对铁矿南矿段的矿坑涌水量进行预测计算和评价,为采矿提供必要的依据。

Hebei province,Kanshang iron ore block southern is located in the alluvial flood plain of the Luan He river hydro geological zones(Ⅱ)in Luan He river floodplain alluvial flood water-rich pore water and strong sub-region(Ⅱ2),its iron ore resource of 15.09 million tons,due to the iron in a relatively small section of the mine upfront investment in exploration work,and low accuracy,and conditions are very complex,it is necessary to carry out hydro-geological exploration work.Using geophysical,drilling,pumping tests and other methods of work,the basic identification of the Quaternary aquifer and feature-rich aqueous fractured bedrock aquifer water each segment and major iron ore mine south of hydro geological parameters,the aquifer hydraulic connection between its various,there is no fault in the analysis to determine iron ore block south mine,is a multi-stage crushing local bedrock folds cause.Combined feasibility report mining plan,build iron ore blocks south geological model,using a large well method,iron ore mine in southern water inflow forecasting calculation and evaluation,to provide the necessary basis for mining.
