长期以来,工程爆破中主要参数的设计,一直都是凭经验进行的,由已有实践结果的统计数据推算新条件下的主要参数,然后再根据爆破效果加以调整,这种办法是不够科学的。近二十多年来,大量的现场实践,各种电子测试仪器的进步,实验技术及理论研究的快速发展使得爆破破岩机理的一些基本规律已逐渐为人们所了解。这样,在爆破工作中就有可能利用已有的理论研究成果及实验技术,以设计主要参数;从而逐步减少其中“经验”部分所占比重;以后在使用中再经过不断的改进和发展,将有可能用实验和理论计算解决爆破问题,这样也就使
For a long time, the design of the main parameters in engineering blasting has been carried out empirically. The main parameters under the new conditions are deduced from the statistics of the existing practice results and then adjusted according to the blasting effect. This approach is not scientific enough . In recent twenty years, a great deal of field practice, the progress of various electronic testing instruments, the rapid development of experimental techniques and theoretical studies have gradually made some people understand the basic rules of blasting rock breaking mechanism. In this way, it is possible to make use of the existing theoretical research results and experimental techniques in the blasting work in order to design the main parameters so as to gradually reduce the proportion of the “experience” parts therein. After that, in the future, after continuous improvement and development, It is possible to solve the problem of blasting experimentally and theoretically, which also makes it possible
