二道沟金矿采矿方法遇到的困难及解决途径
|
摘要
从宏观上描述了二道沟金矿脉的地质特征,针对不同的矿体特征,尝试了不同的采矿方法,在多年的工程实践中,各式各样的难题不断出现,如岩爆和地表塌陷等,在解决这些问题过程中,采取了不同的施工方案,通过总结工程实践中各种采矿方法的优劣,针对不同采矿方法产生的负面问题,提出了新的解决方案,为类似矿山的采矿生产提供参考经验。
The geological features of the Erdaogou Gold Mine were described in overall,according to different geological characteristics in this Mine,in many years of engineering practice,different stopping methods were tried,all kinds of problems continually appeared,such as rock burst,the earth's surface subsidence etc.Some new methods were used to solve the problems,the merits and demerits of the stopping method in the Erdaogou Gold Mine were mainly described in this paper,and new resolution ways for the difficults of the mining method were suggested,which can supplied practical experiences for other mines' production under the similar conditions.
