Using geochemical anomaly，more and more new mineral resources were found in the forest landscape region of Daxinganling in the recent years.This indicates that geochemical anomaly is an effective method for ore prospecting in the region，a gold geochemical prospecting pattern is of great importance for ore prospecting in the region．Features of gold anomaly were studied on the viewpoint of regional depo sits，soil，geochemical features of rocks，in the paper.And characteristics element anomaly were studiedby multivariate statistical an alysis.Then a pattern of quartz vein type gold mineralization，migmatizating grante type gold mineralization，skarn type and MetaUogenic Setting type gold mineralization was built．And provide a train of thought for prospecting pattern in the region．
Xiaoshiren is a unique gold deposit in Southern JiLin．Its sign's combination has instruction significance，which is best to continue the mine prospecting and evaluate the same gold deposit．Based on the ore-bearing alteration zone．the best combination of signs are with the effective information of Geography、Chemical、Physics constituted．It includes the thick brecciform magnesianmarble silieide．Hematitezation high resistance soil the rock measurement Au anomaly and the anomaly combination of Au Ag As Cu Pb and so on．
Xilaokou gold ore deposit is produced in northern Jiaolai basin，the reason has at the same time the pengjiakuang type level the angle of slip conglomerate gold ore and Jiao Jiashi the breaking alteration crag gold ore multi-skill gold ore deposit．The gold ore east is skidded west the faulted structure the north and Near East to the faulted structure union control．Cold ore main growth in fault zone breccia and marble nature cataclasite and in flowered hillock nature cataclasite isotonia tectonite．Throughto this area geology and the geophysics．the geochemistry characteristic research and the analysis，had pointed out this area prospecting symbolized and prospects the direction．
The Eerguna metallogetic belt lies on the Xing'an-Mongulia orogetic belt，which is on the South-east border of Siberlia Plate．And refers to the zone between the Mongolian-Okhotsk and Derbugan frature belts．It is composed of Upper Heilongjiang(depression)metallogetic subprovinces and Eerguna(uplift)metallogetic subprovinces and Kerulen(depression and uplift)metallogetic subprevinces．There are 13 rock gold deposits(point)related to Mesozoic magmatic activities，and the gold deposits in this area formed in Mesozoic(J3-K1)．Gold deposits in this area are distributed in beIf with northeast direction and in row with northwest direction．The mineralization materials mainly come from deep resources and a little from upper crust．The ore-forming fluid is the mixture of magmatic water and atmospheric water．The temperature of gold mineralization is 200-300℃．The deposit is a meso-epithermal gold deposit．
Zhongzhuang gold deposits lie in the center and southern part of the famous Mu-Ru ore-formed belt．The Au ore-forming conditions are good in Zhongzhuang gold deposits．In this paper，the geological，geochemical and geophysics characteristics of Zhongzhuang gold deposits are summarized and analyzed.The geological characteristics and ore-controlling faults of Zhongzhuang gold deposits are compared with them of Baishi gold deposits and Sunjiagou gold deposits，which belong to the same tectonic belt as Zhongzhuang gold deposits．Then the mineralizing rules are summarized and the ore-searching direction is pointed out for Au in Zhongzhuang gold deposits．
The Iron ore at east Reshuigou is mainly controlled by the stratum of Yingouqun which form early ordovician epoch，the stratum is a condition to find The iron ore there．And another condifion is abnormality of magnetism．The Iron 0re form for volcanic-deposit metamorphose．
NuoHeiQian copper tine deposit is mostly produced in tourmaline-quartz vein．The most of mineralization assemblage is thiophilic minerals and secondary oxides minerals．Cu、Sn minerals areis occurred as associated，but it despear a early and late in generation analysis．The mineralization quartz-vein is the main ore guide and major carrier of copper fine minerals．
Question exists which in view of the Hulalin minning area even tunnels construction，proposed set of pratical and feasible means．
Cyaniding sodium is the whole cyaniding produces homework in most importance of a kind of production material，and also a kind of deadly poison product，its depletion expenses has 30％-35％ of the direct production cost of the cyaniding homework，so adopt measure to lower its dosage is the key of valid production cost，and also for reduce pollution of the environment to create a condition．The cyaniding homework which passes on the spot produces fulfillment and the cyaniding sodium dosage obviously lowers after each production craft condition is excelent to turn and produced considerable economic performance．
In this paper，the author discussed several methods of coordinates transformation of GPS positioning application in mining survey with practical example，these method's are evaluated．And the problem of accuracymestimation are analyzed．
A foam enrichment method for gold was reported in this paper．The foam samples were obmined through simulating experiments．Two methods for gold desorption(sulfourea desorption method，ashing method)were compared and the results showed that the sulfourea desorption method was better the ashing method in evidence．The best experiment term of the different method was obtained through the further experiment．
This paper analyzes brakes system of the hoister and raises conceiving of reform and designs counting method in theroy，summarizes advantage of reform．The reformed braking system is disetype brake．There is less installation and test period，less input，and ensured the safe operation．
The process flow of pouring of large size bimetal bush by fixed pouring technique is summarized．Method to improve the pouring quality of white alloy is put foward．Common quality defects in the pouring of white metal are analyzed and its countermeasures are given out．
Through the circular cone breaker structure and the principle of work analysis，the break-down as well as the processing break down method which in coor with progress of production practice appears，carries on the generalized analysis to the circular cone breaker speeding car phenomenon，and adopts the response the messure，the correct operation，the service facilities，enhance the equipment service factor．
