The study group consisting of the Science and Technology Office of the Ministry of Metallurgy, the General Research Institute of Mining and Metallurgy and the Changsha Mining Research Institute visited the United States in November 1980 to conduct a study tour of new mining technologies. There are ten study units, each with its own advantages. US Department of Mines Washington headquarters is the government's research management agency responsible for scientific research planning, organization and management. The council consists of ten research centers, located in the states, responsible for specific scientific research tasks. One Pittsburgh Security Research Center engaged in mining health and safety, explosives, blasting technology, pressure control and environmental protection, rehabilitation technology, ventilation and dust research; Shuangcheng Mining Research Center,
