A national key project to study the sustainable technological innovations  for China?痵 solid mine industry has produced phase results. Derived from the project are: a technical policy report on mineral resources development, and a revision draft illustrating the major points and explanations for technical policy of mineral resources development. Both reports have been submitted to experts for comments. The project has developed an indictor system with models and methods for evaluating dynamic technological innovations in solid mine industry. It designed supporting components for knowledge based decision-making management, also needed by the dynamic evaluation of technological innovations in the industry.  The project team is now working to program the components. The effort resulted in a technical policy for solid mine resources at the national level, incorporating iron and steel, non-ferrous metal, coal, and non-metal into an integrated industry. The technical policy has sorted out the common technical features of different mineral resources, while showing their differences. The document  is desirable for both macro and classified guidance. The study proposes, in a systematic and clear manner, the key technologies that need national priority support and encouragement, and the obsolete techniques that need to restrict, from a strategic view of resources, economy, ecologically coordinated development, while considering both current and long term needs. The technical policy is believed a powerful tool for providing necessary guidance for the industry.
