Mine Blasting Drilling
Suitable for drilling pre-split holes and loose blasting holes in metal and non-metal mines. 15-20m depth and 90-115mm borehole diameter accurately match mine blasting hole design requirements, improving blasting precision and safety.
Quarry Stone Mining
For blasting drilling in quarry stone mining, the crawler chassis adapts to rugged quarry terrain, efficiently drilling medium-hard rock to provide stable pre-support for the stone mining blasting process.
Roadbed Engineering Blasting
Serving blasting construction of highway and railway roadbeds, the split-type structure enables operation in narrow sites like mountain roadbeds, accurately drilling blasting holes to ensure roadbed project progress and blasting safety.
Water Conservancy Project Blasting
Used for foundation blasting drilling in water conservancy hubs and reservoirs, the pulse reverse dust removal system reduces dust pollution to water conservancy sites, and stable drilling efficiency ensures smooth blasting construction.
Q: How to transport the split-type YQD-115 rig?
A: After disassembly, the main machine and supporting components can be transported separately by flatbed truck. The overall transportation dimension is about 3800×1800×2100mm, and single components are smaller after disassembly, adapting to transportation needs in mountainous areas and narrow mining zones.
Q: Which rock types is this rig suitable for?
A: The standard configuration is suitable for medium-hard rock formations. For harder rock types, you can contact us to select matching drilling tools and hammers to ensure drilling efficiency and equipment stability.
Q: How about the dust removal effect of the rig?
A: It adopts a pulse reverse dust removal system, which effectively collects dust generated during drilling, reduces dust impact on operators and the environment, and meets environmental protection and safety requirements of mining operations.
Q: Is the equipment difficult to operate?
A: Equipped with hydraulic pilot + electric dual control mode, it is precise and easy to operate. Operators can get started after simple training, and we provide detailed operation manuals and after-sales technical guidance.
