Product Overview

The rail‑mounted raise‑boring machine features full mechanization and remote‑control operation. Equipped with roller‑cone cutters and high‑strength DI‑22 threaded drill rods, it delivers high drilling efficiency with low deviation. Installation is fast and foundation‑free for depths under 100 m. It supports 0.9‑2.4 m boreholes down to 280 m, widely applicable to mining, hydropower, metro, civil defence and other underground shaft‑construction projects.

Key Features

1.Safe and Reliable Operation

The rail‑mounted Raise‑Boring Machine adopts fully mechanized operation and remote‑control functions. It keeps operators away from hazardous work zones to deliver a safer, more comfortable working environment.

2.High Drilling Efficiency and Raise Quality

Roller‑cone cutters are used for mechanical rock breaking. It achieves high drilling efficiency with smooth raise wall surfaces and low borehole deviation.

3.Simple Operation & Low Construction Cost

Advanced hydraulic transmission and control systems simplify operation and lower operator workload. High‑level mechanization cuts labour input and overall construction cost, improving project economic benefits.

4.Fast and Simple Installation

The frame‑type main unit is equipped with upper‑and‑lower bracing and positioning, offering high load‑bearing capacity, outstanding stability and structural rigidity. For drilling depths below 100 m, the machine can be put into service without conventional concrete foundation pouring. It greatly shortens installation time, lowers costs and reduces pre‑construction preparation work.

5.High‑Strength Drill Rods

Drill rods adopt DI‑22 threaded connections with coarse threads and a large helix angle. This design mitigates thread galling, thread damage and drill‑rod failure risks, enhancing connection reliability and overall drilling performance.

6.Wide Application Scope

The machine covers borehole diameters of 0.9 m‑2.4 m and maximum drilling depth up to 280 m. It can work together with freezing shaft‑sinking and other shaft construction technologies for combined excavation.

Beyond underground mining, it is suitable for vertical shaft construction and various underground engineering works, such as hydropower, metallurgy, metro, transport, civil air‑defence and military‑industrial infrastructure projects.
