Geological Characteristics And Quality Evaluation Of Granite In The Ormer Ditch, Hami City, Xinjiang

Entrusted by the hami city yinyu limited company,author carry out the research workof Granite in the Ormer ditch, Hami City, Xinjiang. Completed on the basis ofcomprehensive analysis of the test results of geological field investigation and laboratoryanalysis of samples of this paper.Field work, circle the five ore bodies. Collected representative samples and carriedout petrology, chemical, radioactive and ore compressive and flexural; specific gravity,bulk density, porosity and moisture content testing in accordance with the specificationrequirements and mine.Ore quartz K-feldspar syenite rock pale flesh gray （light brown）, the coarsehypidiomorphic-he shaped structure massive structure. Harmful mineral mica andhornblende total≤2%, in line with siliceous raw materials of DZ/T0207-2002glassdecorative stone plaster chrysotile asbestos, talc, wollastonite graphite mineral geologicalexploration standards hornblende and mica shall not be higher than3%requirements.The average content of the ore chemical composition: SiO₂67.86%、Al₂O₃15.98%、Fe₂O₃2.38%、 CaO0.97%、 MgO0.55%、 K₂O5.86%、Na₂O5.35%、 SO₃0.018%、0.24%Loss on ignition. Line with GB/T18601-2009natural granite requirements of thestandard.The radioactive activity analysis were0-0.57, the value is lower than theradionuclides in building materials limited GB6566-2010standard requirementsradioactive specific activity IRa≤1.0and Ir≤1.3.The average compressive strength of ore127.94Mpa average flexural strength of9.68Mpa. The two indicators have reached the the GB/T18601-2009natural granitestandard specified compressive strength of not less than100MPa, flexural strength not lessthan8Mpa requirements.The average proportion of ore to2.65g/cm3, average bulk density as2.59g/cm3, anaverage porosity of2.32%, with an average moisture content of0.12%. ReachedGB/T18601-2009natural granite standard requirements.Carried out a detailed delineation of the ore body joints Measurement and Statistics,The results showed that the joints are not developed. Theoretical blocks rate determinationbased on the statistical results of the joints （theoretical Blocks rate determination usingbody graphic method）, the results were:1orebody average theoretical blocks rate of 47.10%,2orebody average theoretical blocks rateorebody average theoretical43.94%,3blocks rate of38.72%,41.01%of the orebody average theoretical blocks rate of5orebodyaverage theoretical blocks rate of42.59%.（332）+（333） reached DZ/T0207-2002glass siliceous raw materials decorative stoneplaster chrysotile asbestos talc, wollastonite graphite mineral geological explorationstandards lot to explore resources:3,151,800m³of ore blocksthe amount of1.201millioncubic meters. Control of intrinsic economic resources （332）: ore capacity of1,633,600cubic meters, accounting for52%, blocks volume of641,400cubic meters, accounting for53%; inferred intrinsic economic resources （333）: ore1,518,200cubic meters, blocks of559,600m³.To sum up the indicators show that the quality of the ore body delineation stone are inline with or better than the national Granite standard, which can be as a Class A decorativematerials development and utilization, and its reserves reached a certain size, has animportant economic value.
