Abstract: | The explosive forming technology of cartridge with double cumulative energy grooves ensures that the high pressure gas blades penetrate cracks along the presplitting face.This organic combination of presplitting blasting with cumulative blasting makes the application of the cumulative energy presplitting-smooth blasting possible in production.This patented technology will reduce the amount of drilling holes and explosive of unit area by about 50%~65% respectively in prespliting blasting and save the cost about 50%~55%.And besides,it will weaken the harmful action of the blasting to the reserved rock and increase the stability of the rock slope and expedite the construction progress.The spread of the technology will create obviously great economic and social benefits. |
