一、什么叫光面爆破光面爆破简称光爆,是轮廊爆破、周边爆破、预裂爆破、缓冲爆破、控制爆破等的统称。它是随着喷锚支护大力推广而迅速发展起来的一种爆破新技术。目前光爆应用已由浅孔发展到深孔,由平巷峒室发展到竖井,由硬岩发展到软岩,在采矿、隧道、水电等部门得到较为广泛推广。光爆是在岩石爆破工程中获得光整轮廓面的爆破技术,它的特点是:爆破后成型规整,符合设计断面轮廓要求,围岩保持稳定,不产生或很少产生炮震裂缝,所以光爆具有以下优
First, what is the smooth blast Glossy blasting referred to as light burst, is a roundabout blasting, surrounding blasting, pre-cracking blasting, bursting blasting, blast control, etc. collectively. It is a kind of blasting new technology which develops rapidly with the great support of spray anchor support. At present, the application of light explosion has progressed from shallow hole to deep hole, which has been developed from shaft locker to shaft, from hard rock to soft rock, and has been widely promoted in mining, tunnels, hydropower and other departments. Light burst is a blasting technique for obtaining the smooth profile surface in a rock blasting project. Its features are as follows: the profile after blasting is in conformity with the requirements of the profile of the designed section, the surrounding rock is stable, no or few shots are produced, so the light Explosion has the following advantages
