1. Which detonation technique is preferrable in conjunction with B+Gel technology?

All holes are tied together with detonating cord trunkline and detonated instantly with a single blasting cap.

2. Are there any specific devices measuring B+Gel solution density?

B+Gel density can be measured by standard methods, but this generally is not necessary once the proper ratio of pre-mix to water is found. Since rock characteristics (hardness, compressive strength) varies with each individual quarry, some testing may be required to determine the optimum blend.

3. Is B+Gel solution perishable? What is the quality expiration term?

B+Gel solution is not perishable as long as contaminants (mainly mineral salts) are not introduced into the solution. Salts will destroy the polymer thickening agent rendering the mixture useless. This is why water run off from ponds where diamond saws are running should not be used. B+Gel Premix has a shelf life of approximately 12 months. The shelf life of B+Gel Pre-Mix has not yet been determined but we do not recommend using it after 12 months. The improved B+Gel formula does not have the same problem with mineral salts and pH balance.

4. What is the minimum and maximum air temperature allowed for B+Gel usage?

Maximum temp. is unknown, ambient temps. are preferred. Freezing does not affect the performance of B+Gel once it has been loaded into the drill holes.

5. What is the solutant water temperature required?

Ambient or normal ground water temps.

6. What is the base component of the explosion material?

B+Gel contains no explosive materials.

7. Is there explosion inhibition in the B+Gel technology?

B+Gel does not inhibit the detonation of the detonating cord itself. When shooting a line of holes in dimension stone quarries, there is a very narrow window between where the high peak pressure and velocity of the exploding detonating cord drives cracks radially in all directions ( like spokes of a wheel) and the point where the pressure fails to generate a crack even at its weakest point (the next hole in the line). B+Gel works by controling the maximum peak pressure and the time it takes to reach peak pressure to fit inside this window. Also, because of the compressibility of B+Gel, the pressurizing of the hole is dramatically slowed. In a hole 2 meters deep, the det-cord takes about 3 micro seconds to detonate. When B+Gel is added to the hole, maximum pressure is not reached until about 100 micro seconds. Thus allowing adjacent holes to help create the split along the line of closely spaced holes.

8. Are there notary verified documents (certificates) of the State institutions of the ecological and sanitary control, as well as institutions of the quarry development control?

B+Gel is non hazardous and not regulated in the United States. Only MSDS is available.

9. Is B+Gel a passive, inert substance, or component assisting the process of explosion?

B+Gel is totally passive and inert.

10. Can you provide more specific requirements (if any) to detonating cord?

• 25 grains per foot (5 grams per meter)
• 40 grains per foot (8 grams per meter)
• 18 grains per foot (3.5 grams per meter) may be necessary in quarries with extreme shot crack problems.
• Larger cords may be used in quarries that drill holes greater than 32mm diameter and quarries without severe crack problems. This allows for wider spacing which may lower costs.
