Abstract
Methods and equipment have been developed that combine the use of continuous miners, flexible conveyor trains, and longwall mining techniques to provide flexible and efficient removal of resources from subterranean formations. Some methods for use in a mining operation include advancing a continuous miner towards an angled face that extends from a headgate to a tailgate; and performing an angled cutting turn in which the continuous miner turns less than 90°.
Claims9
A method for use in a mining operation, the method comprising:
- advancing a continuous miner towards an angled face that extends from a headgate to a tailgate of a mine;
- performing an angled cutting turn in which the continuous miner turns less than 90°;
- advancing the continuous miner along the angled face to the tail gate in a cutting operation;
- depositing material extracted from the face by the continuous miner on a flexible conveyor train;
- supporting a roof of the mine along the angled face with a plurality of powered roof supports;
- withdrawing the flexible conveyor train along the angled face;
- withdrawing the continuous miner along the angled face;
- and
- sequentially advancing each of the plurality of powered roof supports towards the angled face.
