Blasting equipment is used for both underground and open pit mining operations and is known to be one of the most hazardous aspects of the job. For mining operations to be successful good blast designs are absolutely vital as poor practices and excessive explosives can result in damage to rock structures causing unwanted caving.Get Price
Openpit mining, or opencast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Openpit mines are used when deposits of commercially useful minerals or rocks are found near the surface that is

In the case of placer mining, unconsolidated gravel, or alluvium, is fed into machinery consisting of a hopper and a shaking screen or trommel which frees the desired minerals from the waste gravel. The minerals are then concentrated using sluices or jigs. Large drills are used to sink shafts, excavate stopes and obtain samples for analysis.
however, for largescale open pit mining in particular, the truck and loader34 material movement practice is the preferred method of materials handling Czaplicki, 1992 Ta et al., 2005. Throughout this paper, we consider a loader34 to be any type of high productivity excavating equipment, which may include a mining loader, shovel or excavator.
At sites where ore has been extracted by opencast mining, backfilling has been used often to realize morphological recovery. Backfilling is the process of completely, partly, or selectively filling an openpit mine or a quarry void with waste, mine tailings, waste rock, soil, andor other overburden materials, to restore the original ground
A dragline excavator is a piece of heavy equipment used in civil engineering and surface mining. Draglines fall into two broad categories those that are based on standard, lifting cranes, and the heavy units which have to be built onsite. Most crawler cranes, with an added winch drum on the front, can act as a dragline.

Wheeltractor scrapers are used in the mining industry to dig into the surface of the ground and transport it to different locations using only one machine. This heavy equipment resembles a grader machine, except it has a hopper piece that is filled with the soil or clay materials. Wheeltractor scrapers are often seen in openpit mining
Opencast mining is the oldest method of excavating minerals but the mining operations have been mechanised by the use of heavy earth moving machinery during the last 50 years resulting in excavations on a scale which was unthinkable half a century ago. Equipment 1. Bulldozer

Heavy machinery extracting lignite from Garzweiler surface mine in Germany during 2008. Opencast mines are dug on benches , which describe vertical levels of the hole. The interval of the benches depends on the deposit being mined, the mineral being mined, and the size of the machinery that is being used.
The worldwide mining industry uses large loading and transport vehicles and machines from Liebherr for opencast mining and the extraction of raw materials. These giants move enormous amounts of material under the most arduous conditions and have convinced operators of their high level of reliability.
Welcome back to the surface mining model. In the previous topic, we learned about different types of surface mining operations, about equipment, about different methods that are commonly used to extract coal or different ore deposits. Its not difficult to understand that mining is one of the most dangerous working environments in the world and in this topic, we will go through some of the
Heavy equipment or heavy machinery refers to heavyduty vehicles, specially designed for executing construction tasks, most frequently ones involving earthwork operations or other large construction tasks. Heavy equipment usually comprises five equipment systems implementation, traction, structure, power train, control and information.. Heavy equipment has been used since at least the 1st

Belaz 75710, with a payload capacity of 496t, is the biggest mining dump truck in the world. The ultraheavy dump truck was launched by the Belarusian Company Belaz in October 2013 under an order from a Russian mining company. Sales of Belaz 75710 trucks were scheduled to start in 2014. The truck is 20.6mlong, 8.16mhigh and 9.87mwide.
Coal mining Wikipedia, the free encyclopedia Coalcutting machines were invented in the 1880s. In Canada BC, Australia and South Africa open cast mining is used for both thermal and metallurgical coals. Historically, coal mining has been a very dangerous activity and the list of
