Second-round development and utilization of the geological samples in the prospecting for Daying uranium deposit: Change and innovation of prospecting thinking

The general situation of the paragenetic and associated deposits in coal strata in China and the important significance of the exploitation of these kinds of deposits are reviewed in this paper. The innovation of the prospecting model "coal and uranium jointexploration" in the Daying uranium deposit and the significance and function of the second-round utilization of geological samples obtained from the past drilling cores in coal strata are also summed up. Through case studies, it is proved that the second-round utilization of geological samples obtained from the past drilling cores in coal strata is an efficient means to realize joint-exploration of paragenetic and associated deposits in coal strata. The authors also consider that the Daying prospecting model has extensive application and spreading value.
