Western Mining xitiesan Branch (related information) after the founding of New China in 1953, the then deputy director of the Ministry of Geology and Mineral Resources Division Tong led the city to go to Qinghai mineral reconnaissance geological work, to xitiesan geological survey found a large a lead-zinc body, and roughly measure the ore body length, thickness, estimated reserves, considered to be a very large lead-zinc prospect. Back when Xining electric slag machine maintenance, immediately telegraphed news reports and the Ministry of Geology Siguang Minister and other leaders that the Qinghai Provincial, "find a xitiesan big lead, preliminary estimates reserves of 1,000,000 t" (Tong City, Qinghai tin Iron Mountain lead-zinc discovery "colored past and present", 1992, №2). Based on this discovery, from 1955 to 1958 for mining exploration, has made the Northwest Geological Bureau of six hundred thirty-two teams, six hundred thirty-nine team (in 1957 renamed xitiesan geological team), Ministry of Geology of Northwest Geophysical Battalion ○ four teams, and so do a fairly effective geological exploration work, submit the main geological results: 1957 "Xitieshan lead-zinc deposits geological report," 1958 "Qaidam Xitieshan final lead-zinc Geological Survey Report", proven lead and zinc reserves of 2,891,600 t, became the country's largest lead-zinc deposits. "Black gold" into a "cabbage." Selling a ton of coal still earn less than six dollars, and some companies are producing a loss of more than 20 yuan per ton of coal. This is the industry spread the word. "This year's coal market prices came earlier than expected, more urgent, falling fast, falling deep electric slag machine picture, coal production and operation problems worse." This year, the Shanxi Coal Industry Department of the province in the relevant documents economic performance described in the case of coal. "This year, coal prices decline much, harbor area about 7% decline year on year, this is the result of recent price increases, the decline elsewhere in more than 20%, and now are at a low level over the last three years since." Zhuo Information coal analyst said Liu Dongnuo. Electric slag machine maintenance | Jiamusi Cinder machine | Crawler Cinder machine provided by Gongyi City Xinhua Machinery Factory.
