Why Underground Excavation Is Facing a New Productivity Challenge

If you are involved in mining, tunneling, or underground infrastructure construction, you already understand that excavation speed alone is no longer the only measure of project success.

Today, the real challenge is continuous workflow efficiency—how quickly you can break, load, and remove material without interruption.

In many underground projects, operators face a recurring bottleneck: after blasting or excavation, oversized rock and uneven debris slow down loading operations. This creates downtime, equipment congestion, and workflow imbalance between breaking and hauling systems.

Industry discussions from engineering platforms like Горнодобывающие технологии and underground construction insights from Международная ассоциация туннелирования и подземного космоса consistently highlight one issue:

Material handling inefficiency is one of the largest contributors to underground project delays.

This is exactly where integrated machines like the type 120 crawler mucking loader with hydraulic hammer become critical.

What Is a Type 120 Crawler Mucking Loader with Hydraulic Hammer?

The Type 120 crawler mucking loader is a multifunctional underground machine designed to combine mucking (loading) and hydraulic breaking (hammering) into a single integrated system.

Категории сопутствующего оборудования:

• Подземные погрузчики: Погружной экскаватор
• Выгребающие машины: Погружной экскаватор Тип 80
• Системы горного оборудования: Проходческий комбайн на гусеничном ходу для фрезерования тоннелей, используемый в шахтах

Unlike traditional systems that require separate machines for breaking and loading, this model integrates both functions into one crawler-based platform.

This allows you to:

• Break oversized rock with hydraulic hammer
• Immediately load fragmented material
• Maintain continuous excavation cycles
• Reduce equipment congestion in tunnels

Why Integration of Hammer + Mucking System Is a Game-Changer

In traditional underground operations, workflows are separated:

• Rock is broken using external breakers
• Material is manually cleared or loaded by separate machines
• Hauling systems transport material away

This separation creates delays between each step.

The Type 120 system eliminates this inefficiency by integrating both functions.

Key engineering advantage:

Instead of waiting for one machine to finish, the same unit performs sequential operations without relocation delay.

Engineering Structure of the Type 120 System

1. Hydraulic Hammer Unit

The hydraulic hammer delivers high-impact force for breaking oversized rock formations directly at the working face.

2. Crawler Undercarriage System

The tracked base allows movement across:

• Свободные поверхности скал
• Uneven tunnel floors
• Muddy or wet excavation zones

3. Reinforced Loading Arm System

Designed for continuous mucking cycles with high resistance to impact wear.

4. Dual-Function Hydraulic Circuit

Separate hydraulic control channels ensure stable operation between hammering and loading functions.

5. Станция управления оператором

Ergonomically designed for visibility and precision in low-light underground conditions.

Key Advantages of Type 120 Crawler Mucking Loader With Hydraulic Hammer

1. Dual Function Efficiency

Instead of switching between machines, operators can:

• Break oversized rock
• Immediately load debris

This reduces idle time between operations.

2. Reduced Equipment Congestion

Underground tunnels often suffer from limited space. Using fewer machines:

• Improves movement efficiency
• Reduces collision risk
• Simplifies workflow coordination

3. Higher Cycle Continuity

The biggest productivity improvement comes from eliminating waiting cycles between breaking and loading.

4. Improved Safety Conditions

Fewer machines and fewer manual interventions reduce:

• Worker exposure to unstable rock
• Воздействие пыли
• Риски столкновения оборудования

5. Better Adaptability in Confined Spaces

Crawler systems are designed for:

• Узкие туннели
• Uneven ground
• High-slope excavation zones

Real-World Case Example: Underground Workflow Optimization

In a structured underground excavation scenario based on aggregated engineering field observations:

Before Integration System:

• Separate breaker and loader machines used
• Frequent waiting between operations
• High tunnel congestion
• Average workflow interruptions per shift: multiple cycles
• Uneven material flow

After Type 120 System Deployment:

• Breaking and loading combined
• Reduced machine overlap
• Improved material flow consistency
• Fewer operational delays
• Better coordination between excavation stages

The key improvement was not just productivity but workflow synchronization.
