摘要/Abstract

摘要： 根据矿床赋存条件及围岩性质，提出了一种大直径深孔侧向崩矿新方案, 不单独拉底，用延伸大孔的办法同时崩落矿房与形成平底结构。探讨该方案的采场要素及工艺过程，给出了炸药单耗及试验中所用的装药及联线方式。最终从本次试验中得到了一些有实用价值的结果。

Abstract: Considering the deposit occurrence and wallrock properties, a new approach of large-diameter long-hole side caving is proposed, in which undercut is not made independently but formed by the extension of large diameter holes, which enables the stope room caving and the formation of flat bottom structure.The stope elements and process of this approach are discussed and the unit explosive consumption and the explosive charging and wire connecting mode in the test are described.Some valuable results are gained from the test.

Key words: Large-diameter long-hole side caving, Charge structure, Undercut
