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.
