The coal seam in the southern coal field of the Ordos Basin serves as the main aquifer, while the region is known for its high-intensity coal mining activities. The coupling effect of mine water and the strong disturbance caused by high-intensity mining have brought serious challenges to the stability of coal pillars. To address this, a formula …
The primary ramp of the Pilar underground mine has been completed to level -843, approximately 1,300 meters below surface, following the mineralization of the East Limb.
The room-and-pillar method in coal mining refers to a technique where coal seams are extracted by creating a network of rooms with pillars of coal left in between to support the mine roof. This method has been used for many years and involves the use of mechanized equipment to undercut the coal and extract it from the mine. ... (Mccammon et al ...
With existing production and growth potential, the Pilar Gold Mine is an excellent foundation mine for an emerging gold company.
