摘 要
本设计的井田面积为3.9平方千米，年产量45万吨。井田内煤层赋存比较稳定，煤层倾角28，平均煤厚3.2m，整体地质条件比较简单，在井田范围东部和中央均有断层发育。沼气和二氧化碳含量相对不高，涌水量也不大。根据实际的地质资料情况进行井田开拓和准备方式的初步设计，该矿井决定采用立井家暗斜井二水平开采，设计采用爆破采煤一次采全高回采工艺，走向长壁采煤法，用全部跨落法处理采空区。并对矿井运输、矿井提升、矿井排水和矿井通风等各个生产系统的设备选型计算，以及对矿井安全技术措施和环境保护提出要求，完成整个矿井的初步设计。矿井全部实现机械化，采用先进技术和借鉴已实现高产高效现代化矿井的经验，实现一矿一面高产高效矿井从而达到良好的经济效益和社会效益。
关键词：立井、倾斜长壁、一次采全高、爆破采煤、高产高效

Abstract

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
