Abstract: By using the methods of theoretical analysis and practical calculation, this paper deals with the relationships between compensational exploitation and mineral resources conservation, the determination of the approved mining recovery rate and the actual mining recovery rate, the evaluation of the rational development and utilization of mineral resources as well as the determination of the coerctive mining recovery rate , and puts forward some suggestions to promote the protection and rational development of mineral resources.Researches have indicated that compensational exploitation could effectively prevent mineral resources from being wasted, but may not fully ensure their rational development and utilization. The management of mineral resources should adopt a mode featuring both compensation and supervision. The standard of approved mining recovery rate should not give way to mining methods, instead, major considerations should be given to the mineral resources conditions, which could be determined by establishing a statistical model. The actual recovery rate could be promptly and accurately determined by geographic information system and some other techniques. It is necessary and possible to impose restrictions on the utilization of mining methods featuring low recovery rate by putting into use the coercive mining recovery rate.

Key words: mineral resources, compensational exploitation, rational development and utilization, mining recovery rate, model evaluation
