摘要
作为矿产资源勘查评价的基础,矿床勘查类型划分的合理与否,直接决定勘查的成败及投资的多少。现行DZ/T 0207-2002《玻璃硅质原料饰面石材石膏温石棉硅灰石滑石石墨矿产地质勘查规范》实施以来,指导了玻璃及其他硅质原料矿床的勘查工作,十几年来的实践证明其具有普适性,但也有一定的局限性,如矿床勘查类型的划分。文章在收集大量硅质原料勘查及前人研究成果基础上,对现行勘查规范中的矿床勘查类型划分因素进行深入研究,充分继承现行勘查规范划分因素的优点,调整不适宜之处,并增加了矿床成因类型因素,提出6个矿床成因类型划分因素及权重,赋予相应类型系数。运用其对全国105个硅质原料矿床进行了勘查类型重新划分,有14个矿床勘查类型发生变化,通过对勘查类型改变的典型矿床进行验证显示调整后的划分可能更为合理。本文所讨论研究勘查类型划分内容是对硅质原料勘查技术要求体系完善研究的一次有益尝试,对今后硅质原料矿产勘查开发有一定的借鉴意义。
As the basis for the exploration and evaluation of mineral resources,the rationality of dividing exploration types directly determines the success or failure of exploration and the amount of investment.The current“DZ/T 0207-2002 Specifications for glass-grade silicon materials,ornamental stone,gypsum,chrysotile asbestos,wollastonite,talc and graphite exploration”has guided the exploration of glass and other silicon material deposits since its implementation.It is proved that it has universality for more than ten years,but also has certain limitations,such as the dividing of mineral exploration types.Based on the investigation of a large number of siliceous materials surveys and previous research results,the elements for dividing exploration types of glass silicon materials deposits in the current specifications were further studied,the advantages of the existing exploration specifications were fully inherited,and then the inadequacies were adjusted.After fully discussing the importance of the genesis of the deposits for exploration types,the genesis element been increased,and then six genetic elements for dividing exploration types have been proposed.With reference to the current specifications of using the method of coefficient assignment determine the weights of the elments and assign corresponding type factors.And that using 105 silicon material deposits to vetify the new method,and founding that only 14 deposits had changed.The verification results of typical deposits with altered exploration types show that the adjusted division may be more reasonable.Therefore,the research in this paper is a useful attempt to improve the technical requirements for the exploration of silicon materials.It can be used as a reference for the exploration and development of silicon materials in the future.
