This design well field area is 3.9 square kilometers, the annualoutput 450,000 tons. In the well field the coal bed tax saves quitestably, the coal bed inclination angle 28, average coal thick 3.2m,the overall geological condition quite is simple, and central has thefault growth east the well field scope. The methane and the dioxide carbon content relative are not high,wells up the water volume not to be big. Carries on the well fielddevelopment and the standby mode preliminary design according to theactual geological data situation, this mine pit decided uses verticalshaft inside slope two levels mining, the design uses the demolitionto mine coal time picks entire Gao Huicai the craft, moves towards thelong wall mining coal method, with all cross falls law processing topick the depletion region. And to the mine pit transportation, the mine hoist, the mine pitdrains water and ventilates and so on each production system theequipment shaping computation, as well as sets the request to the minepit security technology measure and the environmental protection,completes the entire mine pit the preliminary design. The mine pitcompletely realizes the mechanization, uses the advanced technologyand the model has realized the high production highly effectivemodernization mine pit experience, realizes an ore high productionhighly effective mine pit thus to achieve the good economic efficiencyand the social efficiency at the same time.
Key word: vertical shaft, incline long wall, full-seam mining,demolition mining coal, high yield highly active
