Risk Assessment And Practice For Golden Geology Explotation

Since the opening up of China's gold market in 2002, the state-owned, private and foreign-invested, three-legged race era for gold development has started with the representatives of Gold, Shangdong Zhaojin, Shangdong Gold-mining, Zijin Mining, Sino Gold etc. To be an invincible position in the future development of gold market, the competitors occupy exploration region consecutively, at the same time, look for more reserved resources quickly, efficiently and cost-effectively is one inevitable choice for gold risk assessment of geological exploration. So to establish gold geological exploration project risk assessment system is the premises of commercial circulation, improvement of exploration's success rate and reduces of exploration cost. This essay will put gold geological exploration project into the ranks of risk investment, introduce the mode of risk assessment as well. To quantify the risk factor that decides the odds of gold geological exploration by integrating the professional particularity of gold geological exploration and exercising vague mathematics theory. Choose the vague risk overall evaluation to establish vague relation matrix between risk measurement and risk factors. According to Project's risk factors and weight, calculate out the overall evaluation result of evaluated objects as probability of risk investment project status; thereby calculate out gold geological exploration project's overall risk level.The essay has selected LNG GOLD MINE project to do empirical research on the basis of follow-up investigation. According to above methods, firstly cognize project completely, make the questionnaire and interview to experts who grade it by using scientific methods to do quantified risk analysis of gold geological exploration. Next classify the risk factors and weight, obtain an overall risk level of project. And then estimate the project's development direction, which has practical guidance significance. It is certain that there're geologic feature differences due to China's vast territory. With the consideration of using vague risk overall evaluation, to make proper modification on those key factors that influences the odds of this project, based on special condition of concrete territory located, in order that the result of project risk evaluation gets closer to project performance.
