The Prevention Of Water In Lilou Iron Ore

Lilou iron ore located in Anhui province Huoqiu county territory.Along with the expanding of the mine production,the hydrogeological conditions which have ascertained can't meet the needs of the production safety,that will lead to water bursting in the process of tunneling and affect the mining work.Integrated several times water burst of mine,it is because of the hydrogeological conditions is researched unclearly,which will lead to many difficulties to accurate projections for the possibility of the mine water gushing and water inflow.Based on different research methods and theoretical basis,finally put forward the corresponding prevention measures and Suggestions for water,to provide theoretical basis for mine safety production and technical guidance in future.According to the new geological and hydrogeological data which producted in build Wells in new reveal.Targeted for downhole joint measurement statistics and observation of tunnel water inflow.The paper analysis of downhole joint development rule by joint statistics of roadway to figure rose to determine deposit structure joint development,combined with the distribution rule of roadway water point,analysis of the relations between the water point and joint development,to further determine the water channel.By collecting water samples data and collecting water samples,using the method of ion concentration contrast and piper three line graphic analysis,according to diversity and similarity of ion concentration in water samples.analysis to determine the source of the mine water.Using the Visual Modflow 3D seepage numerical simulation software,establish reflect the simulation time and space changing rule of groundwater distribution,storage and parameter model,To predict the mining area water inflow and hydrophobic displacement by formulate the plan.
