可燃气云抑爆技术初探

试验表明,在可燃气云爆炸引发过程或爆炸初始阶段,通过喷洒抑爆材料可抑制爆炸燃烧反应进程,继而中断爆炸反应或显著削弱爆炸强度。无机粉末、惰气和水雾是性价比较高的抑爆材料,具有大面积推广的价值。探讨了可燃气云的抑爆机理,并指出可燃气云抑爆技术后续研究中亟待解决的问题,为可燃气云抑爆技术的实际应用提供了技术参考。

TECHNOLOGY OF CUMULATIVE PRESPLITTING BLASTING

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.
