摘要

针对煤矿巷道底板锚固施工布孔密集、钻机搬移频繁等问题,为提高巷道底板锚固孔的施工效率,研制的ZDY750L底锚钻机采用分体履带式结构,宽度窄,施工机动性强;采用摇臂式偏转机构,使钻机实现一次停车完成两个底板锚固孔的施工作业。以新元矿3号煤南区集中胶带大巷工业性试验为例,ZDY750L底锚钻机操作简单,移动灵活,定位精确,对底鼓巷道适应性强,降低了工人劳动强度,改善了工作面作业环境,实现了高效施工底板锚固孔作业的功能,为同类煤矿巷道底板治理提供借鉴及指导。
Abstract

In order to meet the technical requirements about the dense arrangement of holes on roadway floor anchoring construction, frequent move of drilling rig and high construction efficiency, the new type of ZDY750L drilling rig for anchoring of floor anchoring in coal mine was developed. It adopts split and crawler structure, has small width, high mo- bility in underground coal mine. Swing arm mechanism completes the construction of two roadway floor anchoring holes with one stop. The results of industrial test in conveyor roadway of southern district of seam 3 in Xinyuan Mine showed that the ZDY750L drilling rig has simple operations, good flexibility, accurate positioning and good adaptability in un- derground coal mine, can reduce the labor intensity, improve the operating environment, realize the function of efficient construction of floor anchoring hole and provide technical support for control of roadway in coal mine.
