Longwall mining Wikipedia

Unlike earlier longwall mining, the use of a conveyor belt parallel to the coal face forced the face to be developed along a straight line. The only other machinery used was an electric cutter to undercut the coal face and electric drills for blasting to drop the face. Once dropped, manual labor was used to load coal on to the conveyor parallel to the face and to place wooden roof props to THE INTRODUCTION OF ROOF BOLTING TO U.S. UNDERGROUND COAL underground coal mining technology. At the beginning of the century, traditional pick mining with hand loading was nearly universal. Undercutting machines had largely replaced picks by 1930, when mechanical loading began the first great transformation of mining (figure 1) 1.

History of Explosives and Blasting Mining Engineer First

Coal mining accounts for two-thirds of consumed explosives of which more than 80% of it is ANFO. Today, sophisticated explosive materials and new technologies are being utilized to improve the quality of life for all of us. Computers are used to drill, log and monitor blastholes — automate blending and delivery with bulk trucks — determine bench heights and face conditions — analyze Surface Mining Methods and EquipmentAugering can be regarded as a supplementary method for open cast mining in cases when coal seams in the highwall would otherwise remain unmined (unless recoverable by underground methods) or when rugged terrain would preclude economic stripping by conventional surface methods.
