in such cases, when dealing with suitable and relatively loose rock, it may be possible to quarry the raw material by ripping and then shifting it with the aid of heavy crawler vehicles. the most important factors in the choice of equipment are the engine power and the weight of the crawler vehicle.
Secondary breaking is typically done using a hydraulic digger fitted with a rock hammer, though crawler cranes with steel drop-balls may be used in some quarries. Crushing can be done in three or four stages, primary (first stage), secondary (second stage), tertiary (third stage) and, in some quarries, a quaternary (fourth stage).

Drilling and blasting is the controlled use of explosives and other methods such as gas pressure blasting pyrotechnics, to break rock for excavation.It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction.The result of rock blasting is often known as a rock cut.. Drilling and blasting currently utilizes many different varieties of
The most common processes that produce respirable silica dust in mining and quarrying are drilling, blasting and cutting silica-containing rock. Most holes drilled for blasting are done with an air powered percussion drill mounted on a tractor crawler. The hole is made with a combination of rotation, impact and thrust of the drill bit.
LIEBHERR Crawler Excavators R 980 SME The R 980 SME is a quarrying excavator which features the modified undercarriage of the next model up in the crawler excavator range, the R 9100 mining excavator.
