前言目前有限元数值分析法已广泛地应用于地下矿山开采等地下工程中。位于辽宁省的红透山铜矿是一个生产多年的老矿,矿体埋深较大,采用地下开采,采矿方法为分层充填法。其开拓系统示意图见图1。其地表标高为400M左右,在-467M中段矿体埋深近900M,中段高为60M。目前已开采到-407M中段,从图1可以看出,竖井位于矿体上盘,竖井离
Preface The current finite element numerical analysis method has been widely used in underground mining and other underground engineering. The Hongtoushan copper mine located in Liaoning Province is an old ore that has been produced for many years. The ore body is buried at a large depth and is mined underground. The mining method is layered filling method. Its development system diagram shown in Figure 1. The surface elevation of 400M or so, -467M in the middle section of the ore body buried nearly 900M, the middle of the high 60M. Has been mined to -407M in the middle, can be seen from Figure 1, the shaft is located in the ore body plate, shaft from
