descrição
XCJR-2000 Emulsion Explosive Charging Jumbo
The XCJR-2000 Emulsion Explosive Charging Jumbo is a specialized vehicle designed for both on-site mixing and bulk emulsion explosive charging operations in underground blasting environments.
This charging jumbo utilizes a pumping-based explosive delivery process, enabling the safe and efficient loading of emulsion explosives directly at the blast site. The system supports:
-
Charging with pre-mixed bulk emulsion explosives, or
-
On-site mixing using emulsion matrix and separate sensitizers/lubricants.
Key Features:
-
Dual Functionality: Capable of both on-site mixing and bulk emulsion explosive charging.
-
Automatic Charging Process: The emulsion explosive and lubricants are first loaded into their respective tanks. Using a delivery hose, a primer is inserted to the bottom of the blast hole, followed by synchronized explosive charging and hose withdrawal.
-
Remote-Controlled Operation: Enables fully automated charging with a maximum hole depth of 45 meters.
-
Adjustable Explosive Density and Power: Ensures optimized energy output according to geological conditions and blast design.
-
Low Rebound Rate: Rebound explosive rate ≤ 1%, contributing to cost savings and safety.
-
High Efficiency: Requires only two operators for the entire charging process.
The XCJR-2000 is ideal for modern underground mining and tunneling operations where high safety, automation, and adaptability to varying conditions are critical.

Application Areas of the XCJR-2000 Emulsion Explosive Charging Jumbo
The XCJR-2000 Emulsion Explosive Charging Jumbo is designed for use in a wide range of underground blasting operations. It integrates on-site mixing and automated emulsion explosive charging technology, making it ideal for environments that demand high safety, precision, and efficiency.
1. Underground Mining
-
Metal and Non-metal Mines:
Suitable for large-scale and medium-scale underground mining operations involving long-hole blasting. It ensures uniform charging, adjustable explosive density, and minimal rebound, improving ore fragmentation and extraction efficiency. -
Coal Mines (non-gassy sections):
Where approved, it can be used for controlled blasting with emulsion explosives in safe zones.
2. Tunnel Construction
-
Hydropower and Water Diversion Tunnels:
Used for driving long tunnels through hard rock formations. Its deep-hole charging capacity (up to 45 meters) is particularly effective for high-efficiency tunnel excavation. -
Transportation Infrastructure (railway, highway, metro tunnels):
Enhances progress and safety in confined tunnel sections where manual charging is difficult or unsafe.
3. National Defense and Military Engineering
-
Applied in the construction of military tunnels, bunkers, and underground defense facilities where precision-controlled blasting is required for structural integrity and worker safety.
4. High-Risk or Hazardous Geological Zones
-
The remote control capability and minimized manpower requirement (only 2 operators) make it ideal for unstable rock formations, high-stress zones, and deep tunnels, reducing exposure to risk.
5. High-Altitude and Remote Operations
-
Its automation and low staffing needs are well suited to plateau regions, remote mountainous sites, and areas with harsh climates where labor access is limited.
Operational Advantages in These Fields
-
Improved Safety: Reduces human exposure near the blast face.
-
Consistency and Control: Precise dosing and uniform hole charging reduce overbreak and underbreak.
-
Productivity Boost: Faster turnaround between drilling and blasting cycles.
-
Environmental Benefits: Minimal explosive rebound and controlled energy output help reduce vibrations and noise.
This combination of deep-hole charging capacity, on-site emulsification, and automated operation makes the XCJR-2000 a key component of modern, intelligent underground blasting systems.
