Quarry blasts assessment and their environmental

2013-6-1  Ground vibrations induced by blasting in the cement quarries are one of the fundamental problems in the quarrying industry and may cause severe damage to the nearby utilities and pipelines. Therefore, a vibration control study plays an important role in the minimization of environmental effects of blasting in quarries.

Summary of Surface Blasting and Damages with

Values of the blasting coefficient can be 9 to 15 for quartzite, between 10 and 17 for most igneous rocks like granite and basalt, and range from 17 to 23 for sedimentary rocks such as limestone (USACE 1972). The blasting coefficient is a good indicator of the degree of spalling, with a higher number indicating greater spalling in the rock.
