矿山设计和建设前的工作,一般称之为建设前期工作。国外称为可行性研究。由于矿山建设具有投资大,周期长,条件复杂,矿产资源赋存隐蔽,未知因素较多,风险大等特点,所以,这项研究对于矿山顺利建成投产,达到预期的技术经济效果极为重要。矿山建设可行性研究工作的目的,就是论证矿山开发及加工处理的技术先进性、经济合理性和建设可能性,为上级领导机关决定所拟建的项目是否可以建设及如何建设提供依据。可行性研究,根据所掌握资料的不同和所做的工作程度,一般可分为机会研究、预可行性研究、详细可行性研究、详细与决策等几个步 Mine design and construction work before, generally known as the construction of pre-work. Abroad as a feasibility study. Due to the characteristics of large investment, long period, complicated conditions, concealed mineral resources, unknown factors and high risk, this study is very important for the successful completion of the mine and the expected technical and economic results. The purpose of the mine construction feasibility study is to demonstrate the technological advance, economic rationality and construction possibility of the mine development and processing and provide the basis for the decision of the superior leading authority on whether the proposed project can be constructed and how to build it. Feasibility study, according to the different information and work done, can generally be divided into opportunity research, pre-feasibility study, detailed feasibility study, detailed and decision-making and other steps
