Mining compressor structure

As part of mining operations, Atlas Copco needed to install an industrial compressor directly in the excavation area. The equipment had to be protected by a compressor structure capable of withstanding major mechanical force, including the impact of a bulldozer pushing the platform against the mine wall.

The mandate was to design an industrial compressor structure robust enough to absorb the impact of the mechanical force, while also withstanding the constant pressure exerted by the surrounding earth.

We first produced a detailed shop drawing to precisely define the configuration of the compressor structure and anticipate stress areas. This step was essential to ensure a consistent design that could be validated by an engineer.

Fabrication was then carried out in our welding shop in Montreal by a professional welder, using MIG welding to ensure strong, uniform assemblies throughout the metal structure.

To increase mechanical strength and durability in an underground environment, reinforcement welds were performed using flux-cored (FCAW) welding. This process was selected to maximize weld strength and ensure better performance against moisture, dirt, and abrasive conditions associated with an in-ground installation.
