| Ore mining technical conditions is an important research content as evalua-tionof ore deposit,is decision or influence of mining method and the technicalmeasures ofgeological and technical factors. It is includes the orebody scale, quantity, attitude,shape, buried depth and distribution of concentration, oreandrock of roof and floor,the mechanical physical properties (such as rock, ore block degrees, hardness, weight,compressive strength, tensile strength, the shearstrength and the loose coefficient,hydraulic and agglomeration sex, natural restAngle, kuangfen proportion, etc), thebroken belt, fault, of the growing degree of the joints and fissures, production andhuman harmful substances (such as free silica) and the harmful gas content and so on.The Xiongcun copper ore body is buried shallow, deposit hydrogeological andengineering geological condition is sample, which also have good geologicalenvironment conditions. Orebody is a layer, stratoid, slabs produced from MiddleJurassic emplacement with ocular spherical quartz phenocrysts of hornblende quartzdiorite porphyrite and its country rocks in fine grained tuff, large scale ore bed. Nearthe mining area has no surface water, aquifer is single, and water is weaker, ore bodybottom rock water well, deposit make-up water source is relatively meager, deposithydrogeological type is belongs to the arid zone fissure water filling deposit; fissurewater filling deposit subclasses.The Xiongcun copper’s natural types of ores is with pulse-veinlet-dissemi-natedtype mainly copper ore, followed by secondary oxidation enrichment zone of copperoxide ore and secondary oxidation enrichment zone of mixed ore. Ore compositiondominated by copper, associated useful components for gold, silver, zinc, lead.Xiongcun copper deposit is a hard rock, a hard rock group, rock grou-p structure ismore complex, various types of structural surface is developed. Belongs to the technical conditions of exploitation of medium (II) of the en-gineering geologicalproblems in the main deposit (II-2) engineering geological type.Xiongcun copper deposit in engineering area and the area of earthquakehorizontal distance more than50km, activity area earthquake magnitude is not high,the Xiongcun copper deposit in engineering area effect. Due to the different sectionsof the difference of the lifting movement is not strong, not undermine the Quaternaryactive faults, ground stress with little energy, phase or long-term slow release of crust,basically stable area, there is no strong earthqua-kes and geological conditions. Mineand the surrounding the main historical geological disasters for debris flow, landslide,no environmental pollution and radioactive contamination. |
