在泽良诺夫斯克铅业联合企业的矿山,1953年开始用阶段强制崩落采矿法开采焉斯良斯克工业矿带中部。目前差不多整个矿床都用达个采矿法开采。广泛运用阶段强制崩落采矿法的结果,得以开采贫矿体,并促使矿量开采强度和采掘工作主要过程的机械化水平大大提高。因此,1958—1963年矿石产量大大提高,劳动生产率 In Zeljanovsk, a joint venture of mining enterprises, began in 1953 with the stage of the Forced Caving Mining Method mining Middleware industrial belt central. Almost the entire deposit is currently mined by a mining method. Extensive use of the results of the forced caving mining stage has enabled the exploitation of poor ore bodies and has led to a significant increase in the strength of the mining capacity and the mechanization of the main processes of mining. Therefore, the ore production in 1958-1963 was greatly increased and labor productivity was raised
