Through the researches to the unusual characteristics of sediment geochemistry in outer water of Liba Deposit,the paper thinks this area is very potential,Ag is an close indicate element,As,Sb,Pb are far indicate elements.The paper points out that in the fracture zone in NWW which near the fracture zone in NNW linking to D2S,Au elements combination unusual area is a most important target.
Since Hetai Gold Mine as auriferous ductile shear zone metamorphosed mylonite gold deposit was found in 1980's by civil mining,the government invested a lot in exploration of gold deposits,and it also caught many geological workers’attention.Through study on stratum,tectonics and magma rock relevant to its existence,conclusion is made that mineralization of auriferous ductile shear zone metamorphosed mylonite gold deposit of Hetai Gold Mine has a close relation to formation,transfer and geotectonic evolution of fluidity mineral resources.
This paper is based upon the geological data of prospecting and mining,through the comprehensive analysis on the ore-cont rolling structures,dike screen effect's,and characteristic of geochemistry,it findlly put forward the appearance model of plural cont rolling f ractor and Chinese word“入”RU pattern.And succeeded the appearance prognostication of blind orebody at depth of No.1 vein.Ry means of the prospecting model-gallery combine with drilling-first work on the level drilling-then exploration combine with miming,gain a good result of exploration.
According to many times geological exploration and mapping and collecting a lot of geological data of SIshan deposit,and by carefully analyzing of the data,the author established such model for exploration as:macroscopic metallogenetic trend combines with micro-geologic metallogenetic information and system metallogenetic regulation (commonness) combine with concrete metallogenetic factors (character) of the deposit.By the application of the model,and the studying of the metallogenetic factors,metallogenetic regulations,the author established beneficial metallogenetic district of the deposit.The exploratory works obtained the important breakthrough at the depth of Sishan deposit,finded certain industry and future reserves,attaining the purpose to prolong the service time limit of Sishan deposit.
This text tries to construct to control lovely gold mine in study in regulation in output in in system,mineral in mineral farmland nine deep a mineral vein systems space extends the trend,controling primarily the mineral break the takes the space crosses to wear to slice relation and it's extension trends,then predicting the deep possible the position of output in a mineral,producing for the mineral mountain to explore the mineral with the deep department the of fering consults basis.
Mining thin quartz vein ore body of non-steady highdipping ore and rock in Honghuagou gold mine.Since dry filling of mining was used on early the seventies of the twentieth century,after underwent experimentation and reformation time after time,stope technics gained lots of Specialty and innovation.This article introduce it simply.
The characteristics of ref ractory gocd ores and the principles of selecting pret reatment program are introduced.The deretopmeent and new trends of the methods of roast,pressure oxidation and bio-oxidation in recent years are nutsheu.
IN the situation of software technology continually innovated and the requirement of information technology in the mine industry is imminenc. use C + + Builder as programme tool & utilize SQL2000 database combine with AUTOCAD 2002 developed the MIS of geology measure mining obtained expected result in mining management aspect.
Spur gears were used more in mine machinery equipment,they would be abandoned if wore out.Kinds of technology were int roduced here.
The VVVF Speed Controllers Using in Guangdong Gaoyao Hetai Gold Mine mill run factory,to good at the efficiency and economize electricity. The summarize at underside.
The mining car has a big range of oscillation in the hoisting cage when hoisting.The retarder has a stimulative effect,which has higher reliability,easy to maintain & higher safety factor.The theory & its defect of yoke linkage were talked about in this article,and the theory & state-of-art of the reformed pry bar retarder were mentioned too.
The continuity & need of mine productive power & power ensure system were talked in this article,& alsoits experiences & lessons.
