Blasting and Controlling Techique of High and Steep Rock Slope

Blasting and controlling technique of high and steep rock slope, differing from common blasting,have their special complexity. While,in the course of blasting design and implementation,the rock geology characteristic and environment should be sufficiently realized, and the scheme of blasting and valid protection measures should be established. According to the structural characteristic of rock slope and environment of Shi Ban-fang,this paper introduces the principle of controlled blasting and the scheme of pre-splitting blasting and loose blasting. Some technique measures of how to control blasting flying rock and rolling stone are introduced. The methods above are used in realistic engineering and ideal result is obtained.
