The Study On The Forecast Of Water Inflow During Turing Open Pit Into Undergound Mining In ShiRengou Iron Mine

Iron mine is one of the main raw material in Tangshan steel Company mineralmountain. Because the underground mining engineering was set up on open-air mine notyet ends , so it was put for-ward how to provent and drain water to defend .To can beaccurate estimate mineral pit flow out the circumstance of water, we can adopt thecowgirl defend the catchment measure, guarantee the mineral mountain mine safeproceeding.This thesis passes to the thorough research of the iron mine hydrology geology InShirengou , containing to the mineral area the layer of water proceeded the meticulousanalysis, on the basis of the thing that analyse the Shirengou iron ore water-bearingstratum , broke to just the mineral bed before the water inflow make a dimension ,two dimension flow of describe, establish the Shirengou iron mine intend threedimension flow mathematics model.This thesis make use of the mathematics model established to proceed the estimate ofamount of flow out water.The folio adopts the segment of inside flows out the amount ofwater estimate result expresses, south area -60 m inside the segment of biggest to flowout the water measures is 12620 m3/ d, south area -120 m inside the segment of biggestto flow out the water measures is 14900 m3/ d, north area -16 m inside the segment ofbiggest to flow out the water measures is 19750 m3/ d. The mineral pit part flows out theamount of water higher, have the possibility of the inrush water, in actual work ofmineral mountain, to attain run before to explore the water, defend to get in not yet.Aim at the actual circumstance of Shirengou iron mine in Shirengou this thesis putforward the prevention and cure water measure that underground mine again, makingShirengou iron mine open-air to turn the underground mine and can guarantees in asafety and dependablely proceeds.The text establish Shirengou iron mine intends three dimension flowed the truereaction in model in mathematics the Shirengou iron mine the objective exsitting of havemutually the water power contacts of contain the water layer construction characteristic,that model is in imitate many layers contain water layer construction, led waterboundary with predict the mineral pit flow out the water measures etc. aspect, it is veryflexible and convenient , having realistic directive significance.
