Feb 25 2018 The choice of an underground mining method depends on a range of factors and these include the size and shape of the deposit the orientation or slope of the deposit the depth of the deposit geological structures characteristics of the ore and the surrounding rocks and issues with gas and water In combination these factors allow us to determine an appropriate arrangement and sequence for Emphasis will be on underground mining methods currently being used t operating mines in the NWT as well as the most common mining methods used for different commodities and different ground conditions Mining terminology equipment and career possibilities will be highlighted Surface Mining Techniques Surface mining of coal is characterized by the use of large capitalintensive and efficient mining equipment First the overlying soil and rock layers overburden are removed The coal is then fractured with explosives or machines and loaded onto vehicles for haulage from the mine site Finally the disturbed

The impact of mining conditions on mechanized mining

Underground Mining Most coal seams are too deep underground for opencast mining and require underground mining a method that currently accounts for about 60 percent of world coal productionIn deep mining the room and pillar or bord and pillar method progresses along the seam while pillars and timber are left standing to support the mine roof Longwall mining is an automated form of underground coal mining characterized by high recovery and extraction rates feasible only in relatively flatlying thick and uniform coal beds A highpowered cutting machine the shearer is passed across the exposed face of coal shearing away broken coal which is continuously hauled away by a floor Underground metalmining methods may be unsupported supported and caving methods and there are numerous variations of each Open stopes roomandpillar and sublevel stoping methods are the most common unsupported methods cutandfill stoping when the fill is often waste from the mine and mill tailings is the most common method of
