现行磷矿地质勘查规范存在问题研究探讨

对现行磷矿地质勘查规范中存在的一些问题进行了研究探讨。主要讨论了勘查类型划分、工程间距的确定、资源量估算、共伴生矿产工业指标等问题。勘查类型的划分应允许有过渡类型;对差异很大的多矿体矿床应针对不同矿体分别确定勘查类型;勘查类型的确定应实行量化指标;勘查工程间距应按不同成因的矿床确定差异标准。各勘查阶段对各类资源量应确定合理的量化比例,并与现行矿业管理政策相统一;对鄂西地区有自然分层的硅酸盐型磷矿床类型中的富矿层资源量估算应调整为按自然分层圈定;对高镁磷矿石一般工业指标应做出调整;对共伴生矿产应根据当前回收利用技术水平制定共伴生矿产回收利用的量化指标。

Stady and discussion on problems in geologic exploration specifications for phosphorus deposit

Aabstract:Some problems existing in geologic exploration Specifications for phosphorus deposit are studied and discussed. This paper mainly discusses the classification of exploration types, the determination of project spacing, the estimation of resource volume, and the industrial index of the associated mineral resources. In the division of exploration types, transitional types should be allowed. The exploration types of different ore bodies should be determined according to different ore bodies for the very different multi- orebody deposits. The type of exploration should be determined by quantitative index. The difference standard of exploration interval should be determined according to the ore deposits of different genesis. At each exploration stage, a reasonable quantitative proportion should be determined for all kinds of resources, which should be unified with the current mining management policies. The estimation of rich mineral resources in silicate type phosphorus deposits with natural stratification in western Hubei should be defined according to natural stratification. The general industrial index of high magnesium phosphorus ore should be adjusted. The quantitative index of the recovery and utilization of the co- associated minerals should be established according to the current level of recovery and utilization technology.
