160-Meter Clear Span Environmental Coal Shed Space Frame: Dust Control and Rapid Assembly

Located in South Africa's arid mining heartland, this 45,000 sqm enclosed coal shed represents a critical leap in sustainable infrastructure. In the mining industry, authorities impose paralyzing fines for fugitive dust pollution. Operators are haunted by the risk of spontaneous coal combustion in enclosed spaces, and the nightmare of erecting a massive roof over continuously running conveyors without halting production. Shijie Heavy Industry eradicated these anxieties by delivering a state-of-the-art barrel vault tubular space frame. Engineered with a 160-meter column-free clear span, this masterpiece allows giant dump trucks to maneuver inside with zero obstruction. By utilizing precision-machined bolted spherical nodes, we eliminated hazardous on-site hot work in a highly combustible environment. To guarantee uninterrupted mining, our teams pre-assembled massive segments and utilized hydraulic strand jacks to incrementally push the structure over the active coal yard. The aerodynamic shape prevents dangerous dust accumulation, while integrated vents naturally exhaust explosive gases. Coated with heavy-duty anti-corrosion armor, the steel resists the acidic environment. By sealing the facility 40 days ahead of the regulatory deadline, Shijie secured the client's permits and safeguarded uninterrupted revenue.
