一、国外非金属矿开发利用的基本经验 1.按就近供应的原则,研究资源-产量-需求体系,把提高非金属地质工作的经济、社会效益作为发展非金属战略的核心内容,这是世界各国非金属地质工作管理的共性。 顺应国家经济发展的迫切需要,不断开拓非金属的运用领域,深化应用研究是国外非金属开发利用所遵循的基本原则。当前一些发达国家在这一领域的动向之一是加强新 I. Basic experience in the development and utilization of non-metallic minerals in foreign countries 1. Based on the principle of supplying the nearest resources, study the resource-production-demand system, and consider the economic and social benefits of non-metallic geological work as the core of the development of non-metallic strategies. This is the world’s The commonality of non-metallic geological work management in various countries. In line with the urgent needs of the country’s economic development, the company continues to explore the fields of application of non-metallic materials, and deepening applied research is the basic principle followed by foreign non-metallic development and utilization. One of the current trends of some developed countries in this field is to strengthen new
