【摘要】：云锡松矿1360中段以下30-14矿体松散破碎,开采难度较大。为满足深部安全及经济合理的开采要求,通过对房柱法和下向进路式分层胶结充填法进行技术经济比较,以及两种方法的数值模拟分析,确定采用下向进路式分层胶结充填法作为30-14矿体的采矿方法。该方法虽然成本高于房柱法,但回采的矿石资源多,创造的经济价值大,比房柱法多获得利润总额5 408万元,且开采的安全性更能得到保障。研究成果为类似矿体开采积累了经验,对矿山生产建设和深部资源开发利用都有实际的指导意义。
[Abstract]:The 30-14 orebody below the middle section 1360 of Yunxi Song Mine is loosely broken, which makes mining more difficult. In order to meet the requirements of deep mining safety and reasonable economy, this paper makes a technical and economic comparison between the housing column method and the down-path stratified cemented filling method, as well as the numerical simulation analysis of the two methods. The method of down-path stratified cementing and filling is adopted as the mining method of 30-14 orebody. Although the cost of this method is higher than that of the housing column method, the mining method has more ore resources and creates a large economic value. The total profit of this method is 54.08 million yuan more than that of the housing column method, and the safety of mining can be guaranteed more. The research results have accumulated experience for the mining of similar orebodies and have practical guiding significance for mine production and construction and exploitation and utilization of deep resources.
