ABSTRACT Xinjiang East Gobi molybdenum ore is the biggest porphyry molybdenum deposit of Xinjiang Province. Through the study of this paper, the geological characteristics, engineering geology, hydrogeology and environmental geology of Xinjiang East Gobi Molybdenum ore and the impact of mining on environment will be fully understood, which provides reliable firsthand information of future mine production to ensure the safety and economy of mine production, and besides, provides guidance for mining of molybdenum minerals in this region under the premise of meeting the requirement of reasonable mining environment and environmental protection. This paper, with Xinjiang East Gobi Molybdenum ore as the research object and combining with field data and related literature, uses the theories and methods of structural geology and petrology, geochemistry to analyze and study the regional geology, ore body occurrence, ore characteristics and geological characteristics of output; combines the theories and methods of hydrogeology, engineering geology, environmental geology to analyze hydrology of surface and underground water, water filling deposit, mining petrofabric, engineering geological characteristics of ore bodies and surrounding rock, engineering geological characteristics of tectonic belt and environmental factors and evaluate the water, labor and geological condition of the mine; analyze the hydrology, engineering geology and environmental change and its impact on mining area in the process of mining and put forward prevention and control measures. The economic evaluation of the East Gobi molybdenum mine is carried out based on the The theory and method of Mineral resource economics jointly Combed with various data and forms, all the aspects related to the economic evaluation are analysed, including the costs and expenses, profit and profit distribution, profitability, financial viability and balance ability, project solvency, uncertainty, etc. Through a series of analysis and research, it is concluded that Xinjiang East Gobi Molybdenum ore is characterized by shallow bury, high grade and thick layer and nearly level put, suitable for large-scale open-pit mining. Most minerals are located below the base level of erosion and hydrogeological conditions is simple; rock type of mine is single, involving half hard rock and hard rock; geological structure is simple and rock weathering on the surface is strong and there is weak intercalation existing in local area, which will have local impact on the mining of ore mine and engineering geological problems do not easily occur in the location; earthquake intensity of mining area is V grade, there are sandstorm, and no radio activism and other bad geological disasters; the geological environment quality of mine is medium; the engineering sewage and environmental impact is within the scope of control in local environment. The statistical results show that the project has a good economic benefits, good financial sustainability, fast declining asset-liability ratio, strong asset liquidity, strong solvency which indicates the repayment terms can be achieved, low breakeven point and strong anti-risk ablility, which inidates that the project is financially viable.
