is loosened by a drilling and blasting unit operation, the blasted 'muck' is loaded and transported up to the crusher plant using either a dumper–shovel combination, dozer–dumper combination, or shovel–truck (tipper) system. The sized limestone from the crusher is then dispatched to the consumer by various means. At the end of

The focus of this research is mainly on designing a local stemming plug within the economic constraints. The plugs are tested on full scale blasting at one of the biggest limestone quarry in Pakistan.

A case study has been provided where data from 1995 till date has helped a limestone open pit mine in improving drill factor from 45 tons/m to 75 tons/m, breakage of limestone from 6.5 tons/kg to 14 tons/kg thus reducing costs by 50% while improving crusher productivity from 764 tons/hour to 932 tons/hour and controlling vibration, flyrock and ...

Mining and construction sites experience ecological consequences, such as ground vibrations and fly rock, owing to blasting activities. Apart from the traditional techniques, it is critical to determine the design parameters of a blast which influence the ground vibrations, created by the blasting activities, and to mitigate the effects of ground vibrations as an end …

A pictorial view of one of the blasting operations carried out during the time of this study is presented in Fig. 4. After taken these readings, the Ewekoro village was visited to see the level of structural damage that might have resulted from the ground vibration induced during the blasting operations in the limestone quarry.
