摘  要
本設(shè)計(jì)的井田面積為3.9平方千米，年產(chǎn)量45萬噸。井田內(nèi)煤層賦存比較穩(wěn)定，煤層傾角28，平均煤厚3.2m，整體地質(zhì)條件比較簡單，在井田范圍東部和中央均有斷層發(fā)育。沼氣和二氧化碳含量相對(duì)不高，涌水量也不大。根據(jù)實(shí)際的地質(zhì)資料情況進(jìn)行井田開拓和準(zhǔn)備方式的初步設(shè)計(jì)，該礦井決定采用立井家暗斜井二水平開采，設(shè)計(jì)采用爆破采煤一次采全高回采工藝，走向長壁采煤法，用全部跨落法處理采空區(qū)。并對(duì)礦井運(yùn)輸、礦井提升、礦井排水和礦井通風(fēng)等各個(gè)生產(chǎn)系統(tǒng)的設(shè)備選型計(jì)算，以及對(duì)礦井安全技術(shù)措施和環(huán)境保護(hù)提出要求，完成整個(gè)礦井的初步設(shè)計(jì)。礦井全部實(shí)現(xiàn)機(jī)械化，采用先進(jìn)技術(shù)和借鑒已實(shí)現(xiàn)高產(chǎn)高效現(xiàn)代化礦井的經(jīng)驗(yàn)，實(shí)現(xiàn)一礦一面高產(chǎn)高效礦井從而達(dá)到良好的經(jīng)濟(jì)效益和社會(huì)效益。

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
