Development and Application of Blast Casting
Blast casting is a highefficiency technique applied in surface mines for overburden removal and results in stripping cost savings According to ballistic theory and centerofmass frame basic movement principles, key factors influencing blast casting effect were analyzed, which include bench height and mining panel width, inclined angle of blast holes, explosive unit consumption (EUC), delayIn smallscale surface mining including small quarries, jackhammers are in common use but in larger quarries and open pits, various types of mechanised rigs are employed They drill holes of up to 350mm diameter and lengths up to 60m Blasting in a mine generally occurs in two phases, primary blasting and secondary blasting Blasting Primary Blasting is the activity in which insitu rock isDrilling and Blasting | Technical Aspects of Mining

Optimized design of drilling and blasting operations in
01/11/2018· 1 Introduction Mining activity is mostly represented by these four main operations: drilling, blasting, loading and hauling For a proper mine planning and design, all of these operations need to be carefully planned in such a manner that can prevent extra loads such as operating costs, environmental footprints, etc Amongst these operations, drilling and blasting are known as the pioneers19/06/2017· Drilling and Blasting in any hard rock mine is the first process to free the ore from the in situ or host rocks The degree and the efficiency through which drilling and blasting is done actually determines the quality of the broken material for eventual downstream processing In surface mining operations, the purpose of drilling into rock is to provide a “blast hole” into which explosivesSurface Mine Drilling and Blasting Procedure using Surpac

Blast Hole Drilling: The Basic Process | RPM Drilling
Blast hole Drilling is a technique used in mining whereby a hole is drilled into the surface of the rock, packed with explosive material, and detonated The aim of this technique is to induce cracks in the inner geology of the surrounding rock, in order to facilitate further drilling and associated mining activity The initial hole into which the explosives are packed is known as the “blastBlast design Calculations and empirical formulas: In designing a blast, following principles should be kept in mind: In construction and in surface mining, millisecond delays are used between charges in a blast There are several basic reasons for doing so: To assure that one or more free faces progress through the shot, providing a consistent burden To enhance fragmentation betweenexplosives – Mining and Blasting
