Following a review of the practice conducted over the past thirty years and a description of five aspects of things marking the advances in underground geophysical prospecting, this paper puts forward some suggestions concerning the orientation of future work with a view to enabling the logging technique of Ministry of Geology and Mineral Resources to have its own characters and opening up the new prospect according to the requirement of the task.Five objectives for future work are proposed in this paper. They are:1. the gradual numeralization of the logging technique:2. to extend application scope of the logging technique and to investigate the possibility of utilizing this technique in regional survey;3. to calculate the grade of the ore bed by means of logging technique;4. the formulation of series and the integrated utilization of borehole geophysical prospecting;5. the further development and advance of hydrologic and engineering logging.
