The well field equally moves towards long 4400m, medium bank long 4500m, coal bed total thickness is , belongs to the coal bed. The design well field mercial production , the recover ableresources is . The service life is 54a. This design mine pit uses the double vertical shaft the developmentway, delimits divides two levels mining. Two water averages for on,descend a mountainmining. Uses the belt area type preparation,backlash type mining, the mining coal craft for synthesismechanization mining coal. The mine pit altogether divides 8 beltsareas, in which reaches produces the belt area is 2, reaches producesworking surface 2. This design belt area for the west area area, thebig lane installs lower part the car type the cart yard, the big laransportation uses two row 10t electric lootive to tow the 3t mine car. The year working day is 330d, the use four, sixthe type work system, the work face length is 210m, each knifeprogress is , shears 9 knives every day The lift technique primarily well uses the promotion,the vice well uses the cage promotion. Only promotes the time is 16hevery day. Because the well field inclines the length to be bigger, also for the coal bed, as well as factor influence and so on coal bedgeology condition, decided in this well field pletely uses inclinesthe long wall to pick mining. Because myself ability is limited, lacks the certain , in this design unavoidably can have some problems, asksfellow experts teacher to point out mistakes.
