矿山设计和建设前的工作,一般称为建设前期工作,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、未知因素较多的特点,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。其目的是在矿山设计和建设前,提出一个对矿山建设有充分事实根据的、科学的、切实的战略计划,对矿山建设有一个正确的判断。这也就是根据确凿的资料,进行详尽的科学分析,如对储量、品位、有害
Mine design and construction work before, generally known as the construction of pre-work, known as the feasibility study abroad. Due to the characteristics of large investment, long period, complicated conditions and many unknown factors, this study is very important for the successful completion of the mine and the expected technical and economic results. Its purpose is to put forward a scientific, practical and strategic plan that has sufficient factual basis for mine construction before mine design and construction and has a correct judgment on mine construction. This is based on conclusive data, a detailed scientific analysis, such as reserves, grade, harmful
