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 systems include: a main gate; and a tailgate connected to the maingate by an active mine face; wherein the active mine face extends at an angle between 95° and 135° relative to the maingate.
Claims19
A system for extracting material from subterranean formation, the system comprising:
- a main gate;
- a tailgate connected to the maingate by an active mine face;
- wherein the active mine face extends at an angle between 95° and 135 relative to the maingate and the active mine face extends between 200 feet and 700 feet from the maingate to the tailgate.
A method for use in a mining operation, the method comprising:
- forming a main gate of a mine;
- forming a tailgate of the mine connected to the main gate by an active mine face;
- wherein the active mine face extends at an angle between 95° and 135 relative to the maingate and the active mine face extends between 200 feet and 700 feet from the main gate to the tailgate.
