The industrial keep the deal of coal seam is 67a for growing of recoverable reserves of bituminous and design well field and serving time limit, pit design is divided with one upright well scheme developing for a faces reach to produce. big alley is arranged, big alley adopt the wiring type generator vehicle of 10t pull the base of 3t unload type mine vehicle transportation, with tape transportation oblique alley, connect every coal seam, the method of coal mining alignment the wall adopts the coal method. The first level is divided into 2 mining districts. The second level is divided into 1 mining districts. This worked district is east 1 worked face. Ords 330 days every year. Adapt “threeeight” work situation， work face is 180 meters length of circle is meters， and times is 7 one day.
