Gansu Yangshan Annan Ore Belt Gold Ore Project Resources Reserves And Mining Condition Proof

The gold takes one kind of precious metal, has mining not easily, the cost to be high, physical property good and so on characteristics, not only serves as the decoration moreover also to entrust with the monetary value function and the important raw material for industry. According to the statistics takes the reserve fund, the world gold preserve had 36000 tons. At present, our country gold mine holds the reserves is 2486 tons, the crag gold mine holds the reserves to account for the working mine total in 1 ton below 83%, provincial capital areas and so on Heilongjiang, Liaoning, Hebei, Jilin, Inner Mongolia presented the regional resources crisis. Resources crisis's mine quantity in sharp growth, has occupied at present the complete gold ore 2/3. The gold shortage of resources, the mine holds the reserves seriously insufficient, is restricts the gold industrial development the key question.This article first introduced the Yangshan Annan gold ore belt project's survey, introduced this project related research background and the research present situation with emphasis. Next introduced the Annan gold ore project's basic situation, narrated this project terrain, the landform and the climate characteristic with emphasis. Third, stresses in view of the former research on to this area foundation geology work research, is weak to the mining area economical implication quantity's research, this article key carries on the proof to this area gold ore resources' reserves and the mining condition, explores a road for next step this area ore power's economical development. To be specific, in the 3rd chapter, this article the industry target which, the amount of resources estimate method used from the amount of resources estimate chooses and rests on, the amount of resources estimate parameter determination, ore body selecting with the estimation, the amount of resources category and aspects and so on block section allocation method amount of resources calculation has carried on the proof to the mining area amount of resources.In the 4th chapter, from aspects and so on ore body geology, ore processing technical nature, ore deposit mining engineering factor, surveying work and quality narration has carried on the proof analysis to this area gold ore mining feasibility. Through conducts the summary research to the ore deposit, each economic indicator table Ming dynasty printed books ore deposit's development has the good economic efficiency and the social efficiency, the opportunities for investment is good, south An Bali in the ore power scope 305 to take sb's pulse groups and in 360 to take sb's pulse group 8-35 scopes may change over to sifts the work, for next step changes over to the substantive development to lay the foundation.
