The authors has studied the structural superimposed halos's features of jinniu mountain gold deposit, Established the model and marks of structural superimposed halos of the blind ore predicition, then make blind ore prediction in the deposit deeps, take out blind ore targets, and obtain good result by using the model, and marks.
East east Kunlun Mountains the section is situated at west the mainland China central orogenie zone east section east Kunlun Mountains Gary east the orogenic zone the section, the metal mineral resource is rich, the prospecting prospect is good. This article through knew to the regional geology characteristic and the typical ore deposit geological feature analysis that, summarized the region mineralization rule, and proposed macroscopically the further prospecting direction, has certain guiding sense to this local development geology minerals surveying work.
Located on the southern side in the middle section of the EW-trending stucture of Nanling，which is also the tectonic superposed-compound position, Hetai Gold Deposit is developed as a large-size gold deposit in the ductile shear belt. On the basis of charateristics of Hetai Gold Deposit, scene-working practice experience, and the alaysis and studies on the provious geological achivements, the relationship between mineralization and such Ore-controlling factors as srate, structure, magmatite, migmatite and etc. has been analysed, the laws of concentracted mineralization has been summarized in this paper. This efforts have laid a firm foundation for the forecasting prospective of ore-finding.
The studied the rock's alteration near the mine and disciplinarian of the mine enrichment, the author suggested that the rock's alteration near the mine were formed during the hydrothermal metamorphism after magmatism, effected by the fracture, formed the fracture alteration zone which effected gold enrichment. The auther discussed the direction meaning of the rock‘s alteration near the mine and enrichment of the mine to find the gold mine.
Through the analysis of prospecting and mining of 11# mineral deposit ore reserves in Gaocun mining area, in order to research this mineral deposit’s morphology changed features and fix industrial targets to obtain reasonable resource reserves. So we can better service for enterprise and society．
The metallogenetic geological background and the deposit geological characteristics is the beginning of this paper. The author proposed the new opinion of ore genesis and established the new
metallogenetic model based on analysis of metallogenic condition of Hetai gold deposit. Genesis of Hetai gold deposit is associated with formation and migration of Liquid·-Source and reformation of the the succeeding tectonic movement，which can be used to look for new favorable regions about gold deposit.
Galinge iron deposit in Geermu city of Qinghai province is located at the middle part of Qimantage back - arc basin of the western segment in the eastern Kunlun Mt. The new investigation shows that the reserves of ore deposits is increased. The analyse thinking that the ore body presents to tier of shapes, the optical lens shape aways along tier which products in a set of the Tan jian shan group of ordovician (OST) in volcanic-sedimentary,rock, extends mole than kilometers, the result is gained from the characters of the geological setting, geological features and deposit scale that the ore belong to the volcanic exhalation sedimentation-magmatic and hydrothermal process super-imposion-reformation ore deposit.
because the open-air gold mine of the Hexi near the village, road, and high wire, so we take the trial in it, by trying, we draw the responsible conclusion to parameter o explosion, and draw the responsible conclusion to how. Thereby, we low the shock of explosion, and low the cost of the explosion, the meleage is very obvious in economy and social.
The work area belong to dry mountain, suitable develop areal geochemical survey. Pass through 1/5 ten thousands water system sediment survey after, one after another developed unusual verified of 1/2.5 ten thousands the secondary halo of ditch system, and had found very perspective Guoluolongwa gold ore. Result indicate, the find ore method in chemical exploration is well effective on such geochemical landscape area.
Nowdays, international gold price is keeping a high level, While the technology of sold production and the cost of production keep stable, So the benefit rate of investing in gold production was greatly increased, which makes it is possible to extract low grade ore. This thesis will discuss the extractable grade of low grade oi'e according the production state of Jintingling Mining CO, ltd.
As the developing and exploiting of the mine resources in Guoluolongwa Gold mine, Dulan. It must lead to destroy Geological environment, bring out geological hazard, give rise to poilution of ecological environment, it must do great harm to the mining ecological environment. At the present, protecting mining geological environment, Preventing and reducing geological problems，controlling such geological problems should be solved greatly.
Change through the equipment renewal and the crushing circuit, Realized the stave craft to change. The aim of increasing mineral handling ability is realized. Dressing ability increase from 140 t/d to 170t/d; the rubbing electrical consume decreased from 3.47 kwh/t to 2.45 kwh/t; the gIind fineness electrical consume by 12.4 kwh/t fails to 7.76 kwh/t.
