Drilling and blasting trolleys break the construction dilemma
Industry pain points
Tunnel drilling and blasting construction has long faced the dilemma of "human sea tactics": it is difficult to recruit blasters at the face, the risk of manual drilling in the surrounding rock crushing section is extremely high, and over-excavation causes a surge in support costs. Traditional manual drilling and blasting is not only inefficient (single hole takes 12 to 15 minutes), but also has frequent safety accidents. Construction of surrounding rock above grade IV is particularly difficult.
Your troubles
Safety risks: manual face operation, landslides and water gushing can easily cause mass deaths and injuries;
Cost out of control: over-excavation rate reaches more than 15%, and support materials are wasted significantly;
Efficiency bottleneck: the speed of manual drilling drops sharply at high altitudes and fault zones, and the average daily footage is less than 6 meters.
Our solution: Intelligent Drilling and Blasting Trolley
For complex geology and extreme working conditions, the new generation of **Drilling Rigs** integrates three core technologies: 1. Precision drilling: The hydraulic horizontal drill arm ensures that the hole spacing parallelism error is ≤2°, and cooperates with the energy-gathering light blasting technology (hole spacing is increased by 1 times), and the over-excavation is controlled within 15cm;
2. Adaptation to extreme working conditions: The plateau DJ3G is equipped with a turbocharged engine + low-temperature resistant steel, and it still maintains a single hole of 2.2m/minute at an altitude of 4180 meters (4 times the manual efficiency);
3. Multi-functional integration: Supports drilling and blasting, anchor bolts, and exploration holes. The Excavator Converted Drilling Rigs module realizes rapid replacement, covering 41~102mm hole diameters.
Actual effect
Safety improvement: The closed cab isolates dust and noise (≤75dB), and the number of personnel on the face is reduced by 72%;
Efficiency leap: XCMG XTD295 can advance 7 meters per day and dig 300 meters of hard rock tunnel per month;
Cost optimization: The loss of drill tools is reduced by 30%, and the consumption of explosives is reduced from 15 yuan/m3 to 11.5 yuan/m3.
Drilling And Splitting Machines Innovator: Reshape the drilling and blasting ecology with lightweight aluminum alloy propulsion beams, anti-stuck drill algorithms, and CO₂ pre-cracking technology.
Product Features
1. Parallel drill arm system: hydraulic horizontal arm ensures the accuracy of hole groups, and light blasting forming does not require trimming;
2. Plateau God of War configuration: turbocharged + air-cooled hydraulic system, -30℃~50℃ full-range operation;
3. Double energy consumption: single cycle saves 1082kWh of electricity, and water slag dust suppression rate is 90%.
Tips
✅Surrounding rock matching: For Class IV surrounding rock, the "eight-shaped groove" drill arm is preferred to improve the utilization rate of blastholes;
✅Maintenance shortcut: The "1+1" maintenance system (1 hour diagnosis + 1 day spare parts delivery) is adopted to reduce downtime by 70%;
✅Regulation adaptation: Mixed explosive trucks need to apply for administrative approval to accelerate the mechanized charging process.
From "human sea battle" to "intelligent control rock breaking", the drilling and blasting trolley is ending the century-old dilemma of tunnel construction with safety, precision and extreme combat power.
