摘要
为了探索眼前山铁矿实现自然崩落法开采的可行性,需要对矿区深部矿岩特性有深入了解。采用人工测线法对眼前山铁矿现场岩体结构面进行了调查,并采用Dips软件开展了节理裂隙特征分析。研究结果表明:该矿区存在3组优势节理组,节理裂隙间距体密度为1.79~2.53条/m 3;眼前山铁矿东部区域节理裂隙虽不够发育,但调查发现的缓倾角节理对自然崩落法的实施具有一定的影响作用。
In order to investigate the feasibility of block caving method to use in Yanqianshan Iron mine,rock mass features in deep mine need to be thoroughly understood.Scan line method was used to investigate the field rock mass structures and the measured data of rock joints and fissures were analyzed with Dips software.The results show that three dominant joint sets exist in this mining area and the volume density of joint spacing is about 1.79~2.53 lines/m 3.The joint and fissure in east Yanqianshan Iron Mine is not sufficient development,while the low-angle joints play a positive effect on the implement of block caving mining.
