| The mine of Yinmusi Lead-zinc in Fengxian started construction in 1986, the 1990 production, design service life of 19 years, has produced 11. Mine middle of the main points of a number of mining Yinmusi Lead-zinc belt of North orebody at the middle 1485,1425,1365 mining has completed 1305 middle-mining project has been completed. Since mid-1305 and mid-1365 to expose ore roadway changes larger trenches between the orebody changes unclear, trenches and 1365 to 1305 between the trenches ore mining caused more difficult. If not for these two trenches between the ore body positioning projections, the project will create more mining waste. Moreover, in view of the middle of 1305 roadway to expose the larger orebody changes and trenches below 1,305 ore exploration of the lower level of control, trenches and 1305 following the development of ore distribution and rational layout of how the middle of 1305 following mining projects has become urgent solution mining is a major geological problems.The project is based on home-lead-zinc deposit of Temple, a mineralization of, of, by combining integrated positioning predictable method of doing positioning prediction of ore. Between 1305-1365 trenches in a geologic forecast and radio waves Tunnel tomography detection of combining integrated positioning forecasting methods; In 1305 120m tunnel following a geological ore forecast, the original halo automatic conductivity and high-resolution tomography detection combination of integrated localization prediction method. Face detection effective control of the length of 990-1250m, 180m depth; Discovery geophysical anomalies and the known ore bodies with higher consistency, in order to determine the delineation of ore forecast absorption rate threshold is about 13, conductivity threshold of about 12, with projections geological information and comprehensive delineation of ore forecast each of ore or ore thick and thin parts of the frame or mineralization of the ore body parts. Through the production practice test will predict the actual ore body and exposed ore production comparison, analysis, forecast this orebody borders and the development of more precise, the rate of ore over 50% of mine production to meet the basic requirements, while the new five-lead-zinc mine, 126,100 tons of stone.Through this research project: Analysis of mineralization, geological and radio wave detection tomography Hang thoroughly comprehensive analysis of mineralization, geology, the original halo automatic conductivity and high-resolution tomography detection analysis between the trenches were deep and lead-zinc in large-scale, high-precision positioning effective way to forecast . Thismethod domestically carried on the forecast to below the lead-zincmine mountain gallery between and the gallery ore body in still to befor the first time.
