ON THE STAGE DIVISION OF RECONNAISSANCE SURVEY EXPLORATION ON URANIUM RESOURCES

This paper proposed the basic principles and bases of the stage division in uranium reconnaissance survey exploration on the basis of the analysises on the significance of the stage division in the uranium reconnaissance survey exploration and the major problems in the stage division projects of the present uranium reconnaissance survey exploration, the significance of the technical-economical evaluation in all stages was also emphasized. And on the basis of this, the scheme of revising the previous "six-stage" and the current "four-stage" divisions (that is, initial reconnaissance survey, detailed reconnaissance survey, preliminary exploration and detailed exploration) into "three-stage division" (including general comment of reconnaissance survey, preliminary comment of detailed reconnaissance survey, detailed comment of exploration) was put forward to the stage division of the present uranium reconnaissance survey exploration in order to be coincident with the temporary provisions for the stage division of geological prospecting and exploration work of mineral resources in China.
