多年以来,留矿采矿法一直广泛应用于我国非煤地下矿山。特别是对一般脉状矿床开采,留矿法至今仍然是一种行之有效的采矿方法。为了适应生产发展的需求,本文侧重就提高留矿法回采强度的途径,谈谈笔者的认识。 (一)关于振动出矿机的应用 生产实践表明,常规留矿法存在下述问题: 1.大块卡斗频繁,影响放矿强度,而且维护工作量大,费用高;
Over the years, stay mining mining law has been widely used in China’s non-coal underground mines. Especially for the exploitation of normal vein deposits, the retention method is still an effective mining method. In order to meet the needs of the development of production, this paper focuses on ways to improve the recovery strength of the ore retention method, to talk about the author’s understanding. (A) of the application of vibrating ore machine Production practice shows that the conventional retention method has the following problems: 1. Chuck often frequent, affecting the ore discharge intensity, and the maintenance workload, high cost;
