IV. International Environment and Trend Prediction of Mining Development 1. World Resources Situation (1) The contradiction between social and economic development needs and the limited nature of mineral resources is becoming increasingly acute. Since World War II, the demand for mineral resources by humans has been increasing. In 1986, the The statistics of a country show that the per capita GNP has a linear positive correlation with energy and resource consumption: when the per capita GNP is less than 1,000 U.S. dollars, the per capita energy consumption is below 1,500 kilograms; when the per capita GDP is 4,000 U.S. dollars, the per capita energy consumption Reached 10,000 kg or more. In recent years, due to the influence of the new technology revolution,
