一、控制爆破基本原理控制爆破基本原理主要是指在爆破工程中控制爆破振动,爆破抛掷,爆破声响及爆破破坏范围的基本原理。由于控制爆破是在诸如预裂爆破、光面爆破、松动爆破等爆破技术的基础上发展起来的,因而它吸取了上述爆破技术的一些特点和有用的那一部分,如:爆破作用原理、介质的成缝机理、不偶合装药原理等等。(一)爆破作用原理众所周知,在密实固体介质中,药卷爆炸时产生的爆轰压力可达5～10万大气压。在这种超高压作 I. Basic Principles of Controlled Blasting The basic principles of controlled blasting mainly refer to the basic principles of controlling blasting vibration, blasting and throwing, blasting sound and blasting damage scope in blasting engineering. Since controlled blasting is developed on the basis of blasting techniques such as presplit blasting, smooth blasting, loose blasting, etc., it absorbs some of the features of blasting technology described above and useful parts, such as: blasting principle, medium Slotting mechanism, principle of uncoupled charge, etc. (a) The principle of the blasting action It is well-known that in dense solid media, the detonation pressure generated when the cartridges explode can reach 5 to 10 million atmospheres. In this kind of ultra high pressure
