东乡铜矿一期基建工程虽然已于1980年结束,但由于原设计规模过大和采矿能力过小等原因,所以矿山常年铜矿石实际生产能力仅400～500吨/日。1978年冶金部和江西铜业公司考虑到该矿地质条件复杂,开采难度大,采矿法过于单一,原用的那种分层崩落法(简称原法,下同)问题多,产量上不去,便确定了“东乡铜矿厚陡矿体高效率采矿法试验”这个科研项目,下达我院和东乡铜矿。 几年来在冶金部、江西铜业公司和我院科研部门的关怀和支持下,由于东乡铜矿各级组
Although the first phase of Dongxiang Copper Mine Infrastructure Project ended in 1980, due to the large scale of the original design and the small mining capacity, the actual annual production capacity of copper ore in the mine is only 400 to 500 tons per day. In 1978, the Ministry of Metallurgy and Jiangxi Copper Company considered that the geological conditions of the mine are complicated, the mining is difficult and the mining method is too simple. The problems of the original caving and caving method (referred to as the original method and the same below) , They confirmed the “Dongxiang copper ore thick and steep ore body high efficiency mining test” this research project, issued to our hospital and Dongxiang copper mine. Over the past few years in the Ministry of Metallurgy, Jiangxi Copper Company and our hospital research department care and support, as Dongxiang Copper Group at all levels
