| Mg has become a21st century green metal promising energy prospects. In many metals become exhausted today, vigorously develop magnesium material is an important guarantee of sustainable development, despite the rich in magnesium content of the Earth’s surface, but the raw materials are not many high-quality magnesium smelting, magnesium smelting as an important raw material of high quality dolomite mine less, in addition to the study area dolomite ore smelting magnesium dolomite not only meet the requirements, can also be used to make the plot dissolved limestone, refractory materials, lining, glass, dolomite use is widespread; therefore strengthen research and geological characteristics of dolomite deposit a schematic of the economic significance of the deposit is necessary. Through the implementation of the project, the district obtained a total amount of325million tons of dolomite mineral resources, good quality ore and dolomite mines in the area have high economic value in use, suitable for large-scale industrial mining, submitted to the State a large high-quality mineral dolomite.Work area is located in the southern margin of the North China Carton, is a secondary structural unit-the southern margin of the North China Craton Song dichotoma station edges, Cambrian deposits occur on Gushan (∈3g) in at orebodies layer like output, occurrence moderate, generally100°-150°, deposit plane irregular oval shape, the control deposit something about2352m, the north-south width of1395m, the thickness of5m～127.90m, an average of85.94m.Comprehensive data collected mine geology and mineral resources, regional metallogenic geological environment analysis, and comparative analysis of typical mining is proposed based on the geological characteristics of the deposit area of research, forecasting metallogenic prospect mines. Achieved major results are as follows:1.Through1:5000topographic survey and geological mapping to identify the distribution of regional stratigraphy, structure and magmatic rocks and ore-bearing rocks distribution studies with enrichment law bonanza ore-bearing rocks in layers.2. And by1:10hydrogeology, engineering geology and environmental geology measure, identify hydrogeological conditions, geological conditions and environmental engineering geological conditions of the work area and use of surface trenching orebody is controlled by sampling and analysis, identify the mine distribution, size, shape, capacity and quality of the ore body shape.3. According to the results of the above work, laid on the main seam drilling deep validation performed to estimate the dolomite mineral resources. Through the regional geological background region dolomite ore mineralization conditions, deposit geological characteristics of the study; field a certain number of rock samples collected through extensive indoor observation sheet analysis to determine the type of ore, mineral composition, structure, construction, interpretation its causes and geological characteristics of the deposit, and analyzed by the economic significance of the study outline its prospects use. |
