目前流行的钻眼爆破破岩方法,是一种古老的低能量的方法.比之于近代的电子束、等离子、激光等高能破岩技术,是十分落后的.普通的钻爆方法,工作面所接受的平均破碎功率密度 ρ=1—3千瓦/米~2,而电子束是10~(10)千瓦/米~2,等离子是11~(11)千瓦/米~2,激光是10~(12)千瓦/米~2.虽然高能技术的功率密度是钻爆法的十几个数量级,然而它的掘进速度并不是钻爆法的十几个数量级,
The current popular drilling and blasting rock breaking method is an old low-energy method, which is very backward compared with modern high-energy rock breaking technologies such as electron beam, plasma and laser, etc. Ordinary drilling and blasting method, working face The average crushing power density accepted is ρ = 1 to 3 kW / m 2 and the electron beam is 10 to 10 kW / m 2 and the plasma is 11 to 11 kW / m 2, (12) kW / m ~ 2. Although the power density of high-energy technology is more than a dozen orders of magnitude of the drilling and blasting method, its drilling speed is not more than a dozen orders of magnitude for drilling and blasting,
