尽管为矿业服务的许多公司都可提供可行性研究，但迄今为止因对该研究缺乏明确定义，研究深度往往不能恰如其份。本文旨在为可行性研究提出一批定义，建立一个界说体系．文中按工作深度将该研究分成四类，以表格形式做了对比，并就依据、所需资料、用途三方面对各类研究做了简要说明。最后还为各类研究的费用提出粗略的参考数字． Although many companies serving the mining industry can provide feasibility studies, so far the lack of a definitive definition of the research often fails to justify the depth of the research. This article aims to put forward a number of definitions for the feasibility study to establish a definition system. According to the depth of work, the study is divided into four categories, which are contrasted in the form of tables. The brief description of all kinds of research is made on the basis of the data, the required information and the application. Finally, a rough reference number is proposed for the costs of various types of research.
