摘要
中深孔超前切顶房柱法改进了传统房柱法的回采方案,较好地解决了高大空场采矿作业的安全与采场运搬问题。本文介绍该法的回采方案及采矿工艺;并将技术经济指标与分段空场法加以比较。
Middle-lengthened hole room-and-pillar mining with advanced overcut is a modification of the traditional room-and-pillar method and shows a better solution to the problems related to operation safety andstope ore handling, as encountered in the large and high open stopes. This modified system is presented in the paper,including the stoping scheme and mining technique. Furthermore, its tech-economic indices are compared with those of the sublevel open stope method.
