Surface mining and underground mining are the two major schools of coal mining. To qualify for surface mining, the coal deposits must be within 5080 meters of the surface. To qualify for surface mining, the coal deposits must be within 5080 meters of the surface.
COAL MINING METHODS. In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam,...
Phoenix steel cord and textile conveyor belts operate in a reliable, economical, and environmentally friendly manner, in surface and underground mining. Phoenix application engineers advise on all individual questions in the planning and development of conveyor belt systems. Phoenix conveyor belts are individually tailored to their intended purpose.
Since the nearsurface coal deposits are becoming exhausted at an alarming rate, augmenting production from underground coal mines has now become the priority of the coal industry in view of the increasing coal demand and growing awareness towards sustainable development.
Whether in an underground mine, surface. mine, or coal preparation plant – mine operators, equipment manufacturers and. consulting engineers turn to Rexnord for their power transmission solutions. Rexnord is with you every step of the way.
Underground Mine. This means that all proposed surface facilities required for Abel Underground Mine, such as buildings, equipment, stockpiles, roads and conveyor systems, can be placed within the existing area of disturbance. No new areas will need to be cleared for surface facilities, and the facilities will be hidden from the majority
In a mine with drift or adit access, the conveyor transport can be all the way to surface but in a mine with only shaft access winding or hoisting of coal in the shaft is required. The use of conveyors introduces a requirement for roadways to be mined as straight as possible with changes of direction minimized as far as possible.
Supplier Caucho Técnica fabricated the 78 splices in 100 days, assisted by Phoenix installation engineers. The world's strongest conveyor belt in use underground is a Phoenocord St 7500. The 8,000meterlong steel cable conveyor belt from Phoenix Conveyor Belt Systems is used in the Prosper II coal mine in Bottrop.

The use of fire retardant conveyor belting accelerated over 60 years ago following a number of serious fires in mining and surface applications. The most disastrous mining fire occurred at the Creswell colliery in the United Kingdom on September 26, 1950. At the time of the fire 232 persons were underground.

Solutions that make underground and surface mining operations more profitable. Your mining operation relies heavily on conveyor belts to transport the material taken out of the ground and get it into production, so the durability and efficiency of your equipment is critical .
It is not only coal that is conveyed from 800 m underground to the surface but also, simultaneously, tailings from the washing plant back underground. The belt is 1400 mm wide, type St 7500, with 10 plus 12 mm covers including protecting reinforcements in both sides.
All conveyor systems have inherent dangers while in motion. Fatal accidents related to working near, inspecting, adjusting or maintaining conveyor belts occur each year at underground and surface mines.

In the underground copper ore operations in Poland's KGHM mines vast and complex belt conveyor systems have been used for horizontal haulage of the runofmine ore from mining .
Deep mines require some form of specific transport system between the surface and the underground level. On the other hand, shallow mines generally require a direct and simple transport system. There has been considerable and continuing debate on the use of shafts or inclined drifts in deep mines.
