Magnesite - Resource Development Stage
I. Geophysical exploration
After the liberation, due to the development of China's steel industry, the requirements for refractory materials prompted a large-scale geological exploration work on magnesite. In particular, a large number of geological surveys and prospecting projects have been invested in the Liaodong Peninsula, and large deposits such as Qingshanhuai, Xiaoshengshui Temple, Yangjiadian, Jinjiabao-Xiafangshen and Yanziyu have been explored. Small deposits.
Geological exploration of Haicheng magnesite (including Wangjiapuzi, Jinjiapuzi and Xiafang body) is a typical example. As early as 1952, the 1st and 2nd teams of the Ministry of Geology cooperated with the Geological Department of Anshan Iron and Steel Company and the Liaodong Mining Company to conduct a geological survey on the Xiafangling mining area and compiled a geological survey report on the magnesite in the Liaoyang two counties of Liaodong Province. ", the magnesite geology, ore body, etc. are described. In 1953, in order to further understand the geological structure of the magnesite near the lower house and the geological characteristics of the deposit and evaluate the prospect of the deposit, the Geological Survey was organized to conduct a geological survey, passing the 34 022 m3 trench exploration and 1:50,000 geological repair. The map and sampling, preliminary understanding of the distribution characteristics of the ore belt and the distribution, scale, shape, occurrence and useful components of the surface ore body, etc., submitted the "General Survey of Xiafangling Magnesite Deposit in Haicheng County, Liaoning Province". In 1958, the Yingkou Geological Brigade of the Provincial Geological Bureau carried out comprehensive exploration work in the Yangjiadian-Jinjiapuzi ore section, and invested 3.2 km2 of 1:2 000 geological maps. The surface was exposed by shallow wells and troughs. The deep construction drilling was 2 545 m. Through the sparse control, through these work, the proven magnesite ore reserves were 90.91 million tons, and the report was not approved due to the poor quality of the exploration project. From 1962 to 1964, the Haicheng Geological Team of the Provincial Geological Bureau explored the Xiafang body section and invested in the main workload: 1:50,000 geological mapping 425.5km2, 1:2 000 geological mapping 1.55km2, drilling 10 678m, basic The shape, scale, occurrence and grade change of the ore body in the Xiafang body section were ascertained, and the final geological exploration report of the Xiafang body section of the lower house body of Jinchengpuzi Magnesite in Haicheng County, Liaoning Province was compiled. The reserves of magnesite are 129 million tons, of which industrial reserves are 84.645 million tons. In 1967, the 220th team of Angang Steel Geological Exploration Company conducted detailed exploration of the Jinjiapuzi ore section. The input workload was 1:1 000 geological mapping 1.84 km2, trench 4 4 983 m3, shallow well 100 m, drilling 13 871.5 m. The proven magnesite reserves are 585 million tons, of which the industrial reserves are 270 million tons. The “Geological Exploration Summary Report of Jinjiapuzizi Magnesite Deposit in Haicheng County, Liaoning Province” was submitted. In 1969, supplementary exploration was carried out on the upper ore body of the Xiafang body section. In 1983, supplementary exploration was carried out between the 0th line and the 240th line of the Xiafang body section. In 1954, drilling was the main means to the Haicheng magnesite belt. The Baozi, Jinjiapuzi and Xiafangzi sections have carried out more comprehensive supplementary exploration work. Through these supplementary explorations, a total of 861 million tons of magnesite were obtained, of which the industrial reserves were 318 million tons.
