Coal
mining equipment has expanded its uses and purposes as the excavation of coal
has boomed in recent decades. Coal is used as a traditional fuel source as well
as in the generation of electricity. Coal mining equipment has been modified
and refurbished with fabricated adaptations to meet the evolving needs of the
industry. Coal mining equipment is subject to needing repair due to the high
demands placed on the parts during mining and processing. Coal mining equipment
should be maintained by the most knowledgeable professionals available, to
ensure optimal safety and efficient production for miners and manufacturers.
Drills
Drill machines are used to drill holes in the rock to place
explosives. The drill machines are specifically designed for the purpose. Hand
used drill machines are mostly used in Pakistan. The approximated cost of one
drill machine set is 85000Rs. Two to three sets are required before touching
the coal reserves.
Coal transport
Once cut, the coal has
to be transported from the face area to the surface. Once the coal is cut from
the seam, it has to be brought out to the surface through a haulage system.
Personnel and Material
Transport
The mode of mine
access (e.g. vertical shaft, inclined drift, in-seam access via outcrop, etc) determines the nature of transport systems used to transport
personnel and materials into the mine.
Ventilation
Good
quality air has to be provided for personnel to breath, to dilute both natural
and introduced (e.g. diesel
exhaust) gases, to dilute or carry away dust and to
provide cooling for personnel and machinery. A small quantity of air may flow
through mine workings naturally but this would be insufficient and uncontrolled
and therefore it is necessary to provide a mechanical means of ventilating the
mine.
Important
aspect which shall be kept in focus is that the ventilation system installed in
first phase gets in sufficient as soon as mine goes beyond 1000 to 1500 feet
underground. The larger ventilation system usually comes in focus after the
coal production is already in process.
Vehicles
Most of mining sites are in remote areas where roads
network is either not in
good shape or does not even exist. An off-road
vehicle is required in mining areas. Off-road vehicles are considered to
be any type of vehicle which is
capable of driving on and off paved or gravel surface. Apart from one off-road vehicle, one sedan car
is required for city usage. Approximate cost of these two vehicles is around 2
Million Rs.
Life of off-road
vehicle is estimated as 6 years after the purchase. In most of the scenarios,
by the time vehicles gets to the point of completely depreciated, coal mine is
in phase of production.
Generators
Mining sites are without the electricity provision. That
creates the need of generators to provide electricity. Approximated cost of
generators for the project is around 250,000Rs
