FRAGMENTATION Better blasts

improvements in fragmentation. The solution uses a static 'blanket' of broken rock overlying the blast to contain this increased blast energy and control rock movement. To produce this broken layer of rock, the subdrill in each blast is significantly increased to preblast (or precondition) the entire stemming region of

crushing fragmentation effects of fragmentation on the crusher. impact of rock fragmentation on crusher. get more info of silica sand mining process equipment . Several studies show that crusher throughput and power consumption are strongly influenced by blast- fragmentation

Operations. "Poor fragmentation of ore and waste material can wipe millions of dollars from the value of a mine. The design of the blast does make a difference and HxM Blast is one of the products we are unveiling at MineQuest 2015 to help. HxM Blast replaces and enhances the functionality of MineSight's ever popular Blast

Jun 01, 2018In holes, the measurement of the velocity of detonation (VOD) helps in comparing and evaluating relative performance of explosives. In this paper a blast performance assessment was conducted based on the results obtained from the steady state VOD measurement of emulsion explosives HEF100 and degree of blast fragmentation conducted on an open pit blast.

expenses, are directly influenced by blast design; post-blast parameters are also affected by the outcome of the blast; secondary blasting, loading and hauling, crusher throughput, and grinder efficiency arerelated to blast-induced fragmentation of the ore (Nielsen and Lownds 1997, McKee et al. 1995).

HxGN Split-ShovelCam monitors shovels, conveyor belts and truck tips into the primary crusher in real time to deliver the key metric of particle size, quantifying post-blast fragmentation. HxGN Split-Desktop delivers manual, off-line coarse rock fragmentation size analysis of muck piles, leach pads and more.

Overly coarse fragmentation will reduce primary crusher throughput. Coarse material will lead to more downtime for clearing crusher bridging and plugging. Poor fragmentation will increase the load to secondary and tertiary crushing stages, if used, because there will be less undersize that can be split off to bypass these stages.

Managing Muckpile Fragmentation

Reduction in blast induced damage Consistent crusher throughput and power draw. Factors Affecting Fragmentation Joint Spacing Joint Condition Geology Burden Spacing Design Energy Energy Partitioning Explosives Fragmentation Joint Strike Dip Bedding Planes Strike

machineries and crushers operating on the site and of primary crusher operating on the plant depends on the ratio of desired fragmentation obtained from the blast. On the other side, a lower ratio of fragmentation decreases the primary blasting costs (Ryu et al.).

Sep 01, 2011Blast fragmentation has far-reaching effects on the performance of equipment and processes throughout the mine. Fragmentation affects the looseness or diggability of the bench face, which influences excavation efficiency, while the throughput and energy costs of primary crushers are directly related to the input feed rock sizes.

Dec 19, 2018A collection of workshop papers providing state-of-the-art reviews on all aspects of fragmentation, including photographic requirements, image enhancement, statistical treatment, and applications in quarrying, mining and minerals processing industries.

The Effects of Blasting on Crushing and Grinding

Overly coarse fragmentation will reduce primary crusher throughput. Coarse material will lead to more downtime for clearing crusher bridging and three rock types when the core sample was not subjected to blast action, and when samples were subjected to blasting by one and by two pieces of detonating cord (1996). For taconite, a

A quantitative research was conducted at Tschudi mine, Tsumeb, Namibia with its main drive being to determine the influence that density and blast parameters has on the performance of a blast. The factors that are most vital to the fragmentation process are classified into three namely: explosive parameters, rock parameters and blast geometry.

1 Effects Of Blast Pressure On The Human Body. Effects of blast pressure on structures and the human body thrown into persons resulting in crush injuries or else projectiles launched by the blast The explosion was initiated in the C drift and reached a maximum pressure of 90100 psi inby the seal Debris from the failed seal from cribs built near the

Our latest online real-time fragmentation analysis products are capable of collecting particle size and real-time shape distribution (length to width ratio), sorting material by colour and also give the material volume in cubic meters per hour. These systems excel at bulk material quality control, detecting broken screens, automatic crusher gapping, ensuring mill input is on specification

muckpile. Therefore, reliable evaluation of fragmentation is a critical mining problem[1]. Production of finer fragments in blasting operation reduces the work-load of primary crushers; therefore increasing the crusher efficiency and reducing the crushing cost. Also crushing rate per hour will increase. 2.
