How This Calculator Works
This tool estimates fuel or energy consumption, cost, and CO₂ emissions for roadheader models based on operating hours and fuel type.
Fuel Calculation Formula:
Fuel/Energy Used = Operating Hours × Consumption Rate (liters or kWh per hour)
CO₂ Emissions = Fuel/Energy Used × Emission Factor
Emission Factors:
- Diesel: 2.68 kg CO₂/liter
- Electric: 0 kg CO₂/kWh (assuming renewable source)
About Roadheaders
Roadheaders are tunneling machines widely used in mining and civil construction for cutting rock and soil. They vary in size and power, making them suitable for different applications.
- Small Roadheader (75 kW): Ideal for small tunnels and soft rock excavation.
- Medium Roadheader (150 kW): Commonly used in mining and metro projects.
- Large Roadheader (300 kW): Designed for hard rock tunneling and large infrastructure projects.
- Electric Roadheader: Eco-friendly option with lower noise and zero direct emissions.
Fuel-Saving Tips:
- Use the appropriate size roadheader for the job to avoid overconsumption.
- Maintain cutting heads and hydraulics regularly.
- Plan excavation sequences to minimize idle time.
- Opt for electric models in urban and underground projects for sustainability.
