丰山铜矿南缘矿带原设计采用无底村分段崩落法开采,经多年生产实践表明该法存在很多问题。为解决这些问题,对其进行技术改进,经可行性研究决定采用分段碎石胶结充填法。该法具有采场结构形式新颖、回采与充填工艺技术先进,对该矿开采技术条件适应性强等优点。工业试验已获初步成效,可望解决矿山生产存在的问题,使生产走出低谷。本文介绍技术改造中的采矿方法衔接问题、分段碎石胶结充填法的回采方案以及充填技术等内容。 The original design of the ore belt at the southern margin of Fengshan Copper Mine was exploited by subsidence caving method at bottomless village. After many years of practice, it shows that the method has many problems. In order to solve these problems, the technical improvements were made to them, and the feasibility study was adopted to adopt the segmented gravel cement filling method. The method has the advantages of novel stope structure, advanced mining and filling technology and strong adaptability to the technical conditions of mining. Industrial tests have achieved initial results, is expected to solve the problems existing in the production of mines, so that production bottomed out. This paper introduces the convergence of mining methods in technological transformation, the mining scheme of sub-graded cemented cemented filling and filling technology.
