Product Introduction

Tunnel boring machines are advanced mechanical equipment used in underground construction and mining operations, for precisely excavating tunnels in hard geological layers. These machines gradually break down rock masses through sturdy rotating cutting heads and durable cutting teeth, thus being able to control the excavation of underground passages in various terrain types. Compared with traditional blasting methods, this technology demonstrates outstanding operational advantages in multiple aspects.


Explosion-proof technology: The explosion-proof function of excavators is a safety protection system specifically designed for flammable and explosive environments, such as coal mines, oil fields, chemical plants, etc. It adopts multiple technical measures to eliminate the risk of explosion during the operation process. Its core features include: explosion-proof engines and electrical systems, which isolate sparks or arcs through sealed, flameproof enclosures and special insulating materials; Anti-static devices and flame-retardant material hoses prevent the accumulation of static electricity or the ignition of flammable gases by high-temperature components. While ensuring operational safety, maintaining equipment efficiency is of vital importance for hazardous working conditions such as mining, oil and gas engineering, and similar critical applications.

Reducing risks: Eliminating explosives can significantly reduce the potential dangers associated with instability and debris accidents caused by vibration. Tunnel boring machines are key assets in contemporary underground engineering. They offer advanced technical solutions that can balance operational efficiency, environmental management, and personnel protection in complex excavation conditions.
