Product Overview

The AT‑2000T Mini Raise‑Boring Machine is a compact raise‑boring unit built for small‑to‑medium underground mines with narrow transport passages, limited working space and low‑clearance conditions. Its modular design offers two travel options: tire‑based self‑propulsion and rail‑guided towing.

It integrates the drilling assembly and travel chassis into one compact, remotely‑controlled unit. This simplifies site‑to‑site relocation and minimizes repeated disassembly and reassembly. Thanks to its flexible positioning system and quick‑disconnect structure, setup and relocation can be completed efficiently. The AT‑2000T is well suited for underground raise construction where space and transport conditions are constrained.

Key Features

1.Compact Design for Easy Transportation

Built in a compact layout, the AT‑2000T can pass through narrow underground tunnels and low‑height work zones. Its small footprint simplifies transportation, relocation and on‑site installation.

2.Remotely‑Controlled Integrated Self‑Propelled Structure

The drilling assembly and travel system are integrated into a single self‑propelled unit to reduce repeated disassembly during relocation. It runs on diesel power for travelling and switches to a 380 V electric motor for drilling work. For long‑haul transport, the machine can be remotely driven onto transport vehicles directly without crane‑assisted loading.

3.Hydraulic 4‑Wheel‑Drive Articulated Chassis

The hydraulic four‑wheel‑drive articulated chassis delivers a tight turning radius and high manoeuvrability for confined underground work areas. Wireless remote control ensures convenient, precise travelling operation.

4.Dual Travel Modes

Two travel modes are available: tire‑based self‑propulsion and rail‑guided towing. By swapping between rail wheels and rubber tires, the machine adapts to both railed and railless underground mining environments.

5.Flexible Drilling Positioning System

Equipped with a flexible positioning system, the drill frame can be vertically adjusted via the front‑wheel lifting mechanism and tilted forwards / backwards by the pitching cylinder. The independently‑controlled top‑bracing cylinder enables fast, accurate alignment of the drilling assembly, greatly simplifying machine positioning and commissioning.

6.Quick‑Disconnect Structure

The drilling assembly connects to the travel chassis via quick‑connect couplings. Hydraulic actuation enables rapid separation of the two major assemblies, cutting time and labour for disassembly, transit and reassembly.

7.Intelligent Monitoring & Protection

The machine supports mechanised operation and wireless remote control, featuring real‑time parameter monitoring, fault alarms and mis‑operation protection. These functions lower risks such as drill‑string sticking, borehole deviation and drill‑rod drop‑off caused by improper operation. A wired control interface is retained for manual operation under special working conditions.
