The demand for construction materials produced by quarry rises in tandem with urbanization. The enormous number of complaints, however, has put the quarry owner under constant pressure to ensure safe blasting operations and minimal blasting effect on the environment. Due to the fact that limestone naturally dissolves in water and creates …
While electronic detonators are perfectly suited for controlled blasting in open pit mines, they also offer great flexibility to production blasts (Dent, 1994; Kay, 2000, Mckinstry et al. 2002; Chavez and Chantry, 2003, Grobler, 2003; Mishra and Gupta 2012). This paper presents a case study of controlled blasting at a limestone mine.
