Beijun Mining Fleet Synergy: How Drill-Muck-Haul Systems Cut Cycles by 32% in Hard Rock Operations

Atacama Copper Belt, Chile — 2025

A mid-sized copper mine in Chile’s Atacama Desert executed a 32% discount in underground mining cycles and 28% decrease fee per ton after deploying Shandong Beijun Machinery’s built-in drill-muck-haul system. This step forward underscores how coordinated operation of mining drill rigs, mucking loaders, LHD loaders, and dump vehicles is redefining effectivity in challenging rock and underground mining.

1. The Precision-Coordinated Workflow

Step 1: Drilling — Precision Blast Patterns

Beijun’s hydraulic drill rigs leverage AI-guided positioning to drill 41–76mm diameter holes with sub-5cm accuracy. This precision reduces overbreak by 15% compared to conventional methods, minimizing the volume of fragmented rock for subsequent mucking — a critical time-saver in narrow tunnels.

Step 2: Mucking — Efficient Debris Clearance

Post-blasting, an electric powered electric powered mucking loader with 120m³/h ability and 2.8m width navigates 3-meter tunnels. Its explosion-proof motor (certified for coal mines) transfers particles to a 5-ton LHD loader, whose diesel-electric hybrid device cuts gasoline consumption by means of 20% whilst retaining 4m³ payload efficiency.

Step 3: Hauling — Continuous Material Flow

The chain concludes with a 25-ton underground dump truck, engineered for 30° gradeability and an 8.5m turning radius (15% tighter than industry averages). Its load-adaptive system syncs with the LHD loader’s output, eliminating bottlenecks. Field data shows daily material movement jumps from 8,000 to 11,000 tons in medium-sized operations.

2. Scene-Specific Solutions: From Open Pit to Narrow Seams

Open-Pit Efficiency (Chile Copper Mine)

For surface operations, Beijun pairs deep-drilling rigs (300m capacity) with 50-ton dump trucks. The dump truck’s 8.5m turning radius and reinforced frame handle 35° slopes, lifting overburden removal efficiency by 35%.

Underground Coal (Shanxi, China)

In Shanxi’s narrow coal seams, a compact lineup excels: 1.2m-wide drill rigs, mini mucking loaders, and 10-ton dump trucks. This configuration cuts tunnel damage by 40% (from misaligned loads) and slashes maintenance downtime by 25% — enabled by shared components across Beijun’s fleet.

3. Sustainability Engineered In

Beijun’s electric LHD loaders and hybrid dump trucks form a "zero-emission transport chain", reducing underground CO₂ emissions by 45%. The mucking loader’s dual-filter system traps 99.9% of dust (≤50μg/m³), exceeding EU safety standards. All equipment carries ISO 9001, CE, and China’s MA coal mine certification — critical for global compliance.

"Our integrated fleet cuts total ownership costs by 30% through standardized maintenance and cross-equipment compatibility," explains Beijun’s Chief Engineer. "Mines stop wasting time on mismatched machines — every unit amplifies the others’ strengths."
