block caving coal mining method
What Are the Different Types of Mining? |
Full Answer. In block caving, miners drill tunnels underneath the ore deposits and then draw the material down. In situ mining uses water that is injected into the soil and then pumped back up to the surface where the ore is then removed. In the cutandfill method, .

Block caving Longwall mining is used in horizontal, tabular deposits (mainly coal), while the others have applications in inclined or vertical, massive deposits, almost exclusively metallic or nonmetallic.
NSW Mining Methods NSW Mining
A newer technique is blockcaving, where mineral ores – like gold and copper are extracted by collapsing the mineral deposits under their own weight. Australia's first block cave mine opened in 1997 near Parkes, in Central West NSW.

Longwall Mining an overview | ScienceDirect Topics
longwall mining Mining. a mining method in which very long rectangular blocks of coal are defined during the development stage of the mine and then extracted in a single continuous operation by an automated cutting head moving parallel to the coal face. When the coal is cut, the working area is protected by a movable, powered roof support system.

Feb 28, 2018· Block caving is a technique in which the weight of the overlying rock is itself used to fracture an ore deposit into small pieces, which can then be collected. In this method, a large ore deposit is divided into different sections, or 'blocks'.
top ore caving mining method
A method of mining to increase the ore fragmentation in block caving, using the strain relief cracks surrounding the cave's back, produced during the caving progression. Intermixed (TOR) and (FF) boreholes are down drilled from top of the block up to undercut drifts.
