PRELIMINARY ASSESSMENT OF THE EFFECTS OF BLAST
fragmentation is very crucial in designing a blasting programme The size of fragment is an important factor to evaluate the efficiency and productivity of blasting [1], [2] If rock fragmentation is not accessed regularly, production cost and time delay in quarrying process can increase beyond expectationAs quarry operations are essentially a process of converting solid rock into smaller particles of a desired fragmentation distribution, this“It is now common practice in the quarrying industry and standard practice within EPC’s drilling and blasting operations, for all quarry faces to be profiled usingfragmentation of rock by blasting from quarry faces in fragmentation of rock by blasting from quarry faces in malaysia Blast fragmentation photographs are analysed using image analysis software Photographs are useful to calculate blasted rock volume This paper describes two case studies In one of aggregate (granite) quarry in Malaysia, with Get pricemethods to blast rock in quarry
Effects of Rock Mass Conditions and Blasting Standard on
Rock blasting is the rock excavation technique most widely adopted in the various fields of the mining and construction industries because of its economical and efficient aspects [1] In surface mines and quarries, the main objective is to exact the largest possible quantity at minimum cost 1 Introduction Rock fragmentation distribution influences a range of mining and milling processes including load and haul rates, crushing and grinding performance and ore recovery in beneficiation processes (Michaud et al, 1997)In opencast mining, where blasting is employed for excavation, the overall cost effectiveness of the production operations is compatible with optimization Rock fragmentation control in opencast blasting malaysia flyrock from rock blasting As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any sizereduction requirements including quarry, aggregate, and different kinds of minerals We can provide you the complete stone crushing and beneficiation plantWe also supply stand malaysia flyrock from rock blasting
