Key Considerations When Selecting Power Systems for Underground Mining

Operational Demands and Environmental Conditions

Underground mining is a hard job. It happens in tight tunnels with little air flow, lots of dampness, and changing temperatures. Machines need to be small, strong, and able to handle tough conditions. For example, the DALI WJ-2 Load Haul Dump (LHD) is built for narrow vein mining. It has a compact size of 7000x1700x2050mm and works well from -15°C to +45°C. At altitudes from -1500m to +3000m, when the temperature is 25°C or lower, it has no engine power loss. These details matter when picking between diesel and electric systems.

Safety Standards and Regulatory Compliance

Safety is the top concern in mining. Machines must follow strict rules. The DALI WJ-1 LHD has ROPS/FOPS certified canopies. It also has alarms for oil temperature, pressure, and electrical issues. These keep workers safe. The WJ-1 helps mines move more tons while keeping costs low. Safety features like SAHR (Spring Applied Hydraulically Released) brakes are key for both Diesel LHD and Electric LHD models.

Total Cost of Ownership Over Equipment Lifecycle

The price to buy a machine is important. But total cost of ownership (TCO) looks at more. It includes fuel or power costs, repairs, part replacements, and downtime. Electric underground mining equipment often costs more at first. But it saves money over time. It has fewer moving parts and needs less fuel. It also cuts ventilation costs.

Overview of Diesel LHD in Underground Mining Applications

Performance Characteristics of Diesel LHD Equipment

Diesel LHDs are known for strong power and long work ranges. The DALI WJ-3 LHD gives 164kW of power. It has a tramming capacity of 7000 kg and a maximum breakout force of 131 kN. The DLWJ-3 is a 7-ton Load-Haul-Dump (LHD) made for underground work in many settings. It’s great for medium to large mines that need steady, heavy-duty work.

Comparing Diesel LHD and Electric LHD for Different Mining Scenarios

Productivity Metrics in Varying Tunnel Conditions

In big tunnels, diesel machines like the DALI WJ-4 (10-ton payload) can work longer without refueling. The WJ-4 LHD is made for medium to large underground mines. But in short tasks or shallow mines, Electric LHDs do better. They can recharge quickly and keep going.

Suitability Based on Mine Depth, Ventilation Capacity, and Shift Schedules

Deep mines spend more on air systems for diesel equipment. Electric underground mining equipment saves money here. Mines with short shifts or flexible schedules can handle battery charging better.

Frequently Asked Questions (FAQ)

How do I choose between diesel vs electric based on my mine’s layout?

Look at tunnel size, depth, shift length, air flow, and power sources. Match these to model specs, like the DALI WJ-1 or WJ-4, based on your payload needs.
