and surface facilities at the Metropolitan Coal Mine The approved underground mining Project layout is shown on Figure 1 The Metropolitan Coal Mine Surface Facilities Area is shown on Figure 2 1 1 PURPOSE AND SCOPE The Rehabilitation Strategy has been prepared for the Metropolitan Coal Surface Facilities Area in accordance with Condition 2 of Schedule 6 of the Project Approval Surface-assisted continuous underground mine conveyor Dec 07 1999 The system consists of modular components that are added at the surface and connected underground to form a continuous support structure to the working area such that the infrastructure necessary for the mining operation is expanded or reduced to keep up with the position of the mining face without interruption of operation

Challenging the norm

The success of TBM technology in establishing underground civil infrastructure and providing alternative means of rapid and safe access in poor ground conditions resulted in the consideration of a TBM at the Grosvenor coal mine to establish the conveyor personnel and material (transport) drift access from the surface Considering the geotechnical challenges the TBM excavation method utilised

Conveyor belt cleaners designed to keep product moving efficiently from the face of an underground coal mine or the high wall of a quarry conveyor systems that carry approximately the same material load on the same operating schedule Installing competing belt cleaners on the side-by-side conveyors allowed the plant to compare belt read more used grieve belt conveyor furnace for

Belt Conveyor Belt conveyors used to transport minerals are to be found all around the world in a large number of surface and underground mining operations The idea of using the conveyor belt is not new indeed the first bell conveyors were introduced at the end of the nineteenth century the basic principles of operation have not changed However over the years the capacity rating of belt

South African gold mine experiences have indicated that for the same cost an underground BAC would be capable of achieving 3 C WBT benefits against surface BAC In the case of Australian coal mines the philosophy of a thermal storage system for surface refrigeration plants with large variability in diurnal changes with minimal costs has been considered [48]

The strongest underground conveyor belt was operating in a very interesting installation It is not only r o m coal that is conveyed from 800 m underground to the surface but also simultaneously tailings from the washing plant back underground Conveyor Belts Specifications | Engineering360 Find Conveyor Belts on GlobalSpec by specifications Conveyor belts are used in a wide variety of

Athabasca Oil Sands Project Canada

Forming a belt some 40-60m thick the oil sands sit on the underlying flat limestone beneath clay and sand often covered by a surface layer of water-logged peat between one to three metres deep In around 10% of the Athabasca deposit – an area amounting to some 3 400km – the relatively shallow overburden of less than 75m makes surface mining possible

Surface infrastructure still in use includes mine buildings (offices workshops and change houses) box-cuts to access the coal seam conveyor belt systems and a ROM stockpile facility After operating for six years Tumelo ceased production in January 2014 after its mining contract expired and it was placed on care and maintenance Since then a series of technical and economic evaluations

Mine drainage arising from surface coal mining activities may result in serious pollution The pollutant can be in a physical form (e g sediment) or chemical form (e g acid mine drainage) or a combination of both 6 Surface mining increases the rate of erosion which is a natural process By development and implementation of erosion and sediment control plans before during and after

Improvments in Conveyor Belt Fire Suppression Systems for coal mine Between 2000 and 2009 twenty-five fires in underground coal mines were caused by friction of conveyor belts against pulleys drives rollers idlers and bearings (MSHA) These fires were often not detected for long periods of time after ignition making manual fire fighting difficult or impossible The success of the Get More

Coal mining - Choosing a mining method The various methods of mining a coal seam can be classified under two headings surface mining and underground mining Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods and the choice of which method to use in extracting a coal seam Innovative concepts in underground materials

(3) This surface method was then followed in many instances by the development of underground workings in the form of shafts and galleries (4) Finally a surface operation often on a large-scale would take place (5) Mining was the second of man's endeavors — agriculture was the first (6) Since prehistoric time mining has been integral and essential to man's existence (7

Underground Mines Surface water flowing directly to underground mines through surface cracks subsidence areas and slope drift or shaft mine entries can be a major source of water infiltration Water diversion around such areas will significantly reduce the volume of water entering underground mines A diversion ditch or dike will often effectively divert water around surface openings
