Basic Information
The Coal Mine Mucking Loader (commonly known as a slag-digging machine) is a continuous and highly efficient mining equipment specifically designed for use in underground mines and tunnels. It integrates functions of excavation, slag removal, transportation, and loading, and is the core equipment for mine excavation and slag removal.
I. Equipment Type and Positioning
⭕Core Positioning: Underground / Tunnel Continuous Loading and Discharging Equipment, replacing manual and simple machinery, suitable for narrow tunnels (typically ≥ 1.8×1.8m).
⭕Structural Classification:
●Traveling: Track-type / Wheeled, adaptable to complex underground terrain.
●Power: Electric fully hydraulic (explosion-proof, low noise, environmentally friendly, mainstream in underground environments).
●Conveying: Scraper / Belt Conveyor, directly connected to mine cars / shuttle cars / belt conveyors.
●Industry Classification: Mining Machinery → Underground Mining → Loading and Transportation Equipment (distinguished from open-pit loaders).
II. Core Functions (Features)
⭕Continuous Rock Removal
The mechanical hand (standby claw / rock-digging claw) continuously removes the blasted minerals / rock debris without any interruption, covering the entire working area.
⭕Efficient Material Transportation and Loading
The built-in conveyor directly transports the materials to the mine car, shuttle car or belt conveyor, integrating the processes of excavation, transportation and loading, eliminating the need for secondary transportation.
⭕Coal Mine Chamber Cleaning and Leveling
It can clean the working face, level the coal mine chamber, and remove leftover materials. It has multiple functions in one machine.
⭕Adaptability to Narrow Spaces
The machine body is narrow and has flexible steering, suitable for small and medium-sized cross-section coal mine chambers, filling the gap of mechanized slag removal in narrow spaces.
⭕Safe and Explosion-proof Operations
It uses mine-used explosion-proof electrical equipment, compatible with coal mines / metal mines with gas and dust environments.
III. Core Benefits for the Mining Industry
⭕Significant Improvement in Production Efficiency
●Single machine hourly production capacity is 50–60 m³, replacing 30+ manual slag removal operations, with an efficiency increase of over 10 times.
●Continuous operation, reduced waiting time, and a 30%–50% reduction in tunneling cycle time, resulting in a significant increase in monthly production volume.
⭕Direct Reduction in Operating Costs
●Labor costs: 1–2 operators, replacing a large number of manual workers, saving tens of thousands of yuan in labor costs annually.
●Energy consumption and maintenance: Electric hydraulic is more energy-efficient than fuel; the structure is simple and easy to maintain, reducing downtime.
●Material loss: Precise extraction, less spillage, improved resource recovery rate, and reduced waste.
⭕Safety and Improvement of Working Environment
●Reducing personnel's stay at dangerous work sites, significantly lowering the injury rate, and reducing accident compensation and production downtime.
●Mechanization replacing heavy manual labor, reducing labor intensity, and improving underground working conditions.
⭕Comprehensive Economic Benefits
●The initial investment can typically be recovered within 1–2 years through benefits such as labor, efficiency, and safety.
●Improving the mechanization and intelligence level of the mining industry, enhancing long-term competitiveness and compliance.
