May 17, 2018· Blasting method of ground improvement techniques
Blasting for quarrying for stones may be quite different from blasting for road clearance. In the latter case, the size of the broken stone is of not much consequence. Quarrying by blasting, therefore, requires very experienced persons thoroughly acquainted with blasting explosives on the one hand and strength qualities of rocks on the other hand.
Blasting techniques such as cushion blasting, presplitting, smooth blasting are used to control the unwanted cracks in the remaining rock in conventional blasting. But these techniques develop micro level cracks which are not desirable in dimensional stone extraction. Thus, an improved and cost effective technique is required to control ...
