鹤岗矿务局兴安煤矿于1952年破土动工,1956年投产。投产后只有一个水平生产,设计生产能力150万t/年。1971~1978矿井进行第一次改扩建,一、二水平同时生产,生产能力提高到210万t/年。1981~1988年又进行第二次改扩建,二、三水平同时生产,生产能力提高到400万t/年。二水平为主要生产水平,投产初期只有一个翻笼。第二次改扩建期间增加了一个新翻笼。但随着二水平生产采区全部投产,煤仓不敷使用,经常仓满为
Xingang Coal Mine Xingang Mine broke ground in 1952, put into operation in 1956. After production, only one level of production, design and production capacity of 1.5 million t / year. 1971 ~ 1978 mines for the first expansion, one or two levels at the same time production, production capacity increased to 2.1 million t / year. From 1981 to 1988, a second reconstruction and expansion was carried out and the second and third levels were simultaneously produced. The production capacity was raised to 4 million t / yr. Two levels as the main production level, put into operation only a roll cage. During the second expansion and expansion period, a new turnover was added. However, with the completion of the second-level production mining area put into operation, the use of coal storage is not enough, often full warehouse
