人工矿床勘查开发的若干问题及我国的现状

文章对人工矿床及矿山二次资源的概念进行了讨论，初步提出了人工矿床的3种成因类型，即：技术成因型，技术-自然成因型，稀缺成因型（或市场成因型），分析了人工矿床勘查评价的范围、内容和规范要求；对人工矿床勘查开发技术经济评价的特点，评价准则与评价内容要求进行了论述，并对人工矿床的资源现状进行了分析。提出今后需要深入研究的领域及方向，包括人工矿床的成矿机理、成矿规律，人工矿床勘查开发技术，人工矿床的评价规范制定等。

Several Problems Concerning Exploration and Development of Artificial Deposits and Current Resource Situation of Such Deposits in China

The artificial deposits refer to the deposits formed from such waste heaps discarded in mining activities as tailings and waste rock fillings. These deposits possess the value of redevelopment under suitable technical and economic situations. This paper deals with the concepts of the artificial deposit and the second mine resources, and advances three models for the formation of the artificial deposits, namely deposits of technological origin, those of technological_natural origin, and those of scarce type or marketing origin. The technical situations, the appraisal of the deposit exploration and development, the feasibility of the deposit development and the criteria or principles for the appraisal are studied. The current resource situations of artificial deposits in China are also described. Further researches include ore_forming mechanism, exploration and development technique, assessment norms or standards.
