Investigation And Study On The Groundwater Of An Open-Pit Stope

In the process of mining open pit mine，Effect of bore water for the production of verylarge. Financially speaking，water emulsion explosive hole need more expensive，Theproduction cost is very high.From the perspective of security，The occurrence of borewater affecting blasting effect seriously. If we didn’t promptly dewatering， the slopestability will be affected，resulting inlandslide. To solve the flooding situation open pitproven occurrence of groundwater is very important.First of all, this article discusses the technical methods of groundwater on the impactof open pit methods and abroad to detect groundwater. After High density ResistivityMethod and Ground Penetrating Radar principle of the method of two studies and dataprocessing. We chose these two kinds of geophysical method based on the investigation ofthe open pit mine groundwater.Secondly, For the investigation of geological and hydrologic conditions of an open pitmine of a mining field. To determine the area of rock to slate, dolomite and mica rocks,two faults parallel cutting area may be water channel. At the same time, the use of specialopen pit mine exploitation of stripping.Investigation of water hole through the mining areaexposed strata.Preliminary to draw the distribution map of water rich area.Finally, through the measurement of the exploration area obtained geological data,transferred to the indoor data processing and analysis. Imaging principle of geologicalradar echo signal processing and the migration of the high density resistivity method aredescribed in detail. In addition, according to the high density resistivity data measured byKriging spatial interpolation method to analyze the three-dimensional spatial data. Thehole measured drawing, drawing geological section map and the blasting area forecast planwith high density resistivity profile comparison confirms the analysis, comprehensiveverification get rich water distribution with more accurate.Through the investigation and study of the open pit mine water, The two kinds ofgeophysical method to research is very accurate and reliable, to provide some suggestions for the open pit mine water disaster prevention and control based on determining the waterdistribution and water characteristics of rock. At the same time, to provide reference for therelated research in the field of application of groundwater exploration.
