Mining technology and mining methods are roadway arrangement and in time and space on each other.
Wall System Mining Method General features: a long two coalface with coal face forward, roof exposed area increases, SEAM intense three blasting or broken coal miner , coal , scraper conveyor coal machine , cross- filling method drop method or process gob 4 coalface at least have a roadway ends to form a production system .
Powder mill and crusher mining process , the advantage is adaptable to various geological conditions , technology easy to grasp , simple to manage , for recycling leftover coal , fault -intensive cutting band mining, coal seam thickness upheaval band inclination or exploitation , unstable coal mining and the use of small-scale mining and other high efficiency. Disadvantage is the low level of mechanization , manual labor intensive, working environment and safety conditions are poor and inefficient.

The traditional mining techniques, namely ordinary mechanized mining technology , is mechanically broken coal and loading coal , coal conveyors , single pillar supporting the roof of the mining process . Its support and treatment gob still done manually . Compared with fully mechanized mining , general mining investment less equipment for geological changes easily adaptable face relocation ; compared with blasting mining , high efficiency, and production safety. General mining for promoting short distance , irregular shape, small faults and folds better than the use of developmental face .
A single drum shearer general mining : mining height disadvantage is larger face will divide top and bottom knife cutting twice , increasing the exposed area of ​​the roof and time need to manually open incision followed by low efficiency .
Two pairs of drum shearer general mining : mining achieve a full height . Process of cutting coal , hanging beams, goes conveyors, pillar , back to caving .
