CONCLUSION The study illustrates the challenges posed by geo-mining conditions for blasting at 2m from wagon tippler under construction at one of the limestone mine in India. The smart use of electronic detonators with scientific design and implementation can provide best technical solutions for super controlled blasting near structures under construction.

The rock face to be blasted is typically 40 feet in width by 20 to 25 feet high. A premeditated pattern of 40 to 50 horizontal holes is drilled, with dimensions of 2 inches wide by 12 to 14 feet deep. An emblematic maneuver can drill and blast up to 5 rounds per day, dislodging tons of rock in several diverse headings.

Limestone (calcium carbonate CaCO3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO3. Limestone forms when these minerals precipitate out of water containing dissolved calcium.

ABSTRACT. A survey of pillar conditions was carried out at 21 operating limestone mines that use the room-and-pillar method. The surveyed pillars were all located in rock that was classified as “Good” to “Very Good” using the RMR rock mass classification system. The average pillar width was 14.5m and the width to height ratio varied
