摘要

Controlled blasting methods are used to control blast induced effects such as. over-break, fractures within remaining rock walls and ground vibrations etc. In both the mining and construction industries, blasting is the predominant mctliod for fragmentation of consolidated mineral deposits. Adopting various techniques of controlled blasting such as line drilling, trim (cushion) blasting, smooth (contour or perimeter) blasting, pre-splitting etc,; selecting and employing various parameters of blast design; using modern technology such as precise timing delays, varied density of explosives product by using bulk explosives; muffle blasting at a very critical and congested areas are some of the points discussed in this paper for mitigation of adverse impact of blasting. By adopting these precautions not only the ground vibration is restricted to ease the public relation problem, but the mines'/construction's techno-economics, preservation of host rock strength and safety standard are improved to a considerable level.
