For large-scale demolition and mining projects, efficiency and minimizing borehole density are paramount. Our 115mm diameter O2 rock blasting tube is engineered to deliver precisely that superior performance in large-scale operations. This isn't just a larger tube; it's a strategic solution designed to optimize your project's economics and timeline.

Let's address some common questions about the 115mm tube:

Q: What's the advantage of using a 115mm tube over the 90mm tube?

A: The 115mm tube allows for wider borehole spacing 3 meters compared to 2.5 meters for the 90mm tube. This means fewer boreholes are needed for the same area, significantly reducing drilling time and labor costs. The savings in labor often outweigh the slightly higher cost per 115mm tube, especially on large projects.

Q: How much rock can one 115mm tube blast?

A: The blasting volume depends on factors like tube length (up to 3 meters for a 6-meter borehole), rock type, and borehole spacing. However, the wider spacing with the 115mm tube still provides significant cost savings per cubic meter, maintaining our competitive $1/m³ average.

Q: Is the 115mm tube more expensive?

A: Yes, the individual cost is higher than the 90mm tube. But the reduced labor and drilling time often result in significant overall cost savings, particularly on large projects where the number of boreholes is substantially reduced.

Q: How does the 115mm tube work with the O2 system?

A: The process remains the same: precise drilling, tube insertion, connection to the gas filling tank, liquid oxygen filling, backfilling, safety precautions, remote activation, and final inspection. However, careful planning of borehole placement is crucial to maximize efficiency with the wider spacing.

Q: What types of projects benefit most from the 115mm tube?

A: Large-scale quarry operations, extensive mining projects, and large-scale infrastructure developments where minimizing borehole density is key to efficiency and cost-effectiveness.

Q: What about safety?

A: Safety remains paramount. The controlled expansion of liquid oxygen minimizes shockwaves and flyrock, even with the increased blasting radius of the 115mm tube. Our rigorous safety protocols remain unchanged.
