But what makes the 90mm tube stand out? Let's address some key questions potential customers often have:

 

A: Our research indicates that the 90mm diameter offers the optimal balance between efficiency and cost-effectiveness. While larger diameters could potentially blast more rock per tube, the increased material costs and logistical challenges outweigh the benefits. Smaller diameters, conversely, might require more tubes for the same volume of rock, increasing overall project costs. The 90mm diameter strikes the perfect equilibrium, maximizing the volume of rock fragmented per tube while maintaining cost-efficiency. Of course, we offer tubes in diameters ranging from 40mm to 127mm to cater to diverse project needs; however, the 90mm consistently proves to be the most cost-effective choice for a wide range of applications.

 

A: The volume of rock a single 90mm tube can effectively blast depends on several factors: the tube's length (we offer tubes up to 3 meters long, corresponding to a 6-meter borehole depth), the rock's hardness and geological characteristics, and the spacing between boreholes (typically 2-3 meters). However, as a general guideline, using our recommended borehole spacing and a 3-meter tube, you can expect effective fragmentation within a significant radius around the borehole. Remember, the overall project cost per cubic meter is consistently low, around $1, and decreases further with larger projects.

 

A: The process is straightforward and safe:

Borehole Preparation: A precisely drilled borehole, typically 90mm in diameter and up to 6 meters deep, is prepared. Tube Insertion: The 90mm rock blasting tube is carefully inserted into the borehole, ensuring the inflation tube is readily accessible for connection. Connection & Gas Filling: The tube is securely connected to the gas filling tank using our specialized connection pipe. Liquid oxygen is then carefully introduced until the pressure reaches the pre-determined level. Backfilling & Safety: The area around the borehole is backfilled to prevent flyrock. All personnel are evacuated to a safe distance. Remote Activation: The blasting process is initiated remotely via the control system.
