Mining
is an important engineering activity which is necessary to exploit the
much needed mineral resources which are buried deep beneath the earth
crust and are indispensable for the development of an industrial sector
and infrastructure. To cater the needs of miners, mining excavator has
proved to be very helpful. These mining excavators are available in
various sizes and models which are used in accordance with the size of
the projects. With their efficiency, reliability and extremely low waste
removal costs, mining excavators are very beneficial to the mining
industry.
Mechanical Operations
Mining excavators are armed with modern equipments like pneumatic
cylinders, electric motors, batteries, and compressors. Different types
of mining excavators differ in size and properties. Hydraulic
excavators, bucket wheel excavators and dragline excavators are the
popular excavators that are used in various mining operations.
Hydraulic mining excavators are very similar to any other hydraulic
excavator, except they're much, much larger.
Dragline bucket system consists of a large bucket which is suspended
from a boom. The bucket is maneuvered by means of a number of ropes and
chains. Notable feature of Drag line mining excavator is that they are
not fuel powered like most other mining equipment. Their power
consumption is so great that they have a direct connection to the
high-voltage grid.
Applications
Mining excavators can do lot of work which are associated with the
mining industry. Their work in mining can be summarized as follows :
- Mining excavator is used for different types of surface mining
like open-pit mining, trip mining, quarrying, mountain top removal
and placer Mining.
- Extraction of minerals like coal, petroleum, phosphate, nickel
platinum etc.
- The mass restructuring of the earth in order to reach sediment
as deep as 1,000 feet.
- Extraction of minerals from the earth without tunneling.
- Removal of the soil and rock above the deposit.
