摘要
针对贵州开磷集团用沙坝矿矿体两翼存在走向长近400m的急倾斜破碎矿体,采用浅孔拉槽存在安全性差,生产能力、效率低等问题;为了适应先进的中深孔凿岩台车,在急倾斜破碎矿体中采用中深孔切割拉槽一次成井技术,详细介绍了中深孔切割拉槽的原理及实施方案。
There are broken steep dip ore-body at both wings of the major ore body in Yongshaba Mine, Guizhou Kailin Group. For the part of the ore-body, process of shallow drill slotting used in the process of mining preparation has be unavailable, having poor security, productivity, and low efficient etc. prob- lems. In order to adapt advanced deep drilling car introduced for the mining of the ore-body, process for primary open formation by medium-deep hole slotting in the steep ore-bodies has been applied. The principle and constructing solution of the process are introduced by the paper.
