1、河北理工大學(xué)畢業(yè)設(shè)計摘要摘要本設(shè)計為張雙樓礦1.8Mt/a的礦井設(shè)計。井田走向（東西）長平均約8.23km，傾向（南北）長平均約3.88km，井田水平面積為31.93km2。主采煤層一層，即7號煤層，平均傾角8.9°，厚約5.0m。井田工業(yè)儲量為226.69Mt，可采儲量172.53Mt，礦井服務(wù)年限為73.7a。礦井正常涌水量為320m3/h，最大涌水量為340m3/h；礦井絕對瓦斯涌出量為1.84m3/min，屬低瓦斯礦井；煤層有自燃發(fā)火傾向，發(fā)火期3~6個月，煤塵具有爆炸危險性。開拓方案為立井兩水平開采，暗斜井延深至-700m水平。
2、大巷采用膠帶輸送機(jī)運(yùn)煤，輔助運(yùn)輸采用1.5t固定箱式礦車。設(shè)計首采區(qū)采用采區(qū)準(zhǔn)備方式，采用一次采全高采煤法，全部跨落法處理采空區(qū)。礦井采用中央并列式通風(fēng)。通風(fēng)容易時期礦井總需風(fēng)量4608m3/min，礦井通風(fēng)總阻力2096Pa，風(fēng)阻0.35N·s2/m8，等積孔2.03m2，礦井通風(fēng)容易。礦井通風(fēng)困難時期礦井總風(fēng)量4608m3/min，礦井通風(fēng)總阻力2746Pa，風(fēng)阻0.46N·s2/m8，等積孔1.77m2，礦井通風(fēng)中等困難。關(guān)鍵詞：立井；上下山開采；大采高；中央并列式I河北理工大學(xué)畢業(yè)設(shè)計摘要ABSTRACTThegeneraldes
