The results of blasting affect every other downstream operation in quarrying and mining process. Factors influencing blast results can be classified as either controllable or non-controllable. If desired fragmentation is to be obtained, the controllable factors (blast geometry and explosive properties) must be sufficiently designed to match the non-controllable ones …

Optimization Of Blasting Design Parameters On Open Pit Bench A Case Study Of Nchanga Open Pits Victor Mwango Bowa Abstract: In hard rock mining, blasting is the most productive excavation technique applied to fragment insitu rock to the required size for efficient loading and crushing.
rock blasting works in mining, quarrying and construction Knowledge in common types of explosives used for mining and quarrying (e.g. ANFO, watergels, emulsions) and blasting accessories (e.g. safety fuse, detonators, plain detonators, electric detonators, electric delay detonators, electronic detonators, detonating cord, nonel system and others).
Our SHOTPlus™ range of blast design and modelling software enable users to design, visualise and analyse blast initiation sequences across surface and underground mining, quarry and construction applications.
minimum cost for breaking rock may not be in the best interest of the overall mining system. A little more money spent in the rock-breaking operation can be recovered later from the system and the aim of the coordinator of the mining work should be to achieve a minimum combined cost of drilling, blasting, loading, hauling, crushing and grinding.

blasting of cornices increases efficiency, boring holes along the presumed tension line exposes the ava-lanche blaster to considerable danger. Safety in borehole blasting depends critically on: 1. The blasting crews ability to judge correctly the safe working line. techniques for working with this high explosive (See Chapter 5 - Detonating Cord)..

The hard rock blasting chemical from Easy Blast is made of natural minerals such as calcium oxide. You just have to mix the soundless blasting mixture in cold water and pour it into the drilled hole. Stand back and watch hours of manual demolition work being completed in just a few minutes. There are many benefits in choosing the best rock ...
blasting in conjunction with required presplit blasting or for general rock excavation. The Contractor may also elect to use blasting for trenching operations, structure excavations, and structure demolitions. Permit jobs that involve blasting on State ROW are subject to the same requirements as Department-let contracts.
In a limonite quarry, in Malaysia Murlidhar et al. a model hybrid was used based on Imperial Competitive Algorithm and Artificial Neural Network, in order to predict the breakage of rock through blasting, using as an input data diverse blasting parameters and characteristics of the rock mass. With the evaluation of the model mentioned before ...

Practical New Quarry Metrics Planning and metrics allow you to improve earnings from the rock deposits currently in production. Evaluate your current Metrics used to track your quarry production and profits. Quarries tend to create waste as a consequence of the production process. Quarries tend to waste some profitable reserves.
A FEW TIMING CONCEPTS. first Published: Quarry February 2012. Timing has long been considered the "dark art" of the blasting process, even with the advent of computer timing and blast design packages. Brent Buffham explains why timing in some cases is still a misunderstood aspect of the blasting process and how to address timing gaps.
Blasting is heavily regulated and watched by federal, state and local agencies. In terms of processing, blasting is the critical first step in the rock-fragmentation process. Maximum profitability depends largely on an optimized blast. Consider that drilling and blasting are the first operations performed in any hard rock quarry operation.
of Olenegorsk quarry with single charge blasts. Blasting results for different depth of charge are described by volume of blasting wedge and particle size distribution. Also, kinematic parameters of rock mass movement in strain wave were measured in charge vicinity. Charge diameter in different blasts was 76, 105 mm
Bender (1999) defined production blasting as the type of blasting that is designed to fragment a predetermined volume of rock; widely spaced holes are drilled and fired in a controlled delay sequence.
The explosive column illustrated in Figure 8-6 on the right will produce the best fragmentation. EXPLOSIVES ECONOMICS The economic analysis of the use of explosives is an important part of blasting operations in mining and construction. Explosives are energy, and the efficient use of this energy is a major factor in keeping rock blasting
The content within each article was ahead of its time, putting forth cutting-edge concepts about the mechanics of rock breakage, standards for blasting design, the characteristics of explosives, and material properties, powder factor and the cost of blasting.
