对于金属矿的开采,一般认为分层崩落法与其他采矿法相比,是一种成本高、产量低、木材消耗量大的采矿方法。根据七一五铀矿的开采实况,本文论述采用分层崩落法的适应性和必要性,并着重叙述该方法所存在的主要问题及解决的措施。从而使分层崩落法的主要工艺有所改进。 For the exploitation of metal ores, it is generally accepted that the caving method is a cost-effective, low-yield, and expensive method of mining timber in comparison with other mining methods. According to the actual situation of 751 uranium mining, this article discusses the adaptability and necessity of adopting stratified caving method, and focuses on the main problems of the method and the measures to be solved. So that the main process of subsided caving method has been improved.
