1、山西大同大學(xué)煤炭工程學(xué)院2014屆本科生畢業(yè)設(shè)計(jì)摘要本次設(shè)計(jì)是開采楊千堡煤礦8-1號煤層,煤層厚度為2.4m。據(jù)井田外圍資料調(diào)查該井田為低瓦斯礦井,煤層均有爆炸危險(xiǎn)性。煤的自然傾向?yàn)樽匀济簩?。楊千堡煤礦位于山西省大同市。無論公路還是鐵路,交通運(yùn)輸均較方便。地理坐標(biāo)為北緯:40°00′40″~40°02′34″;東經(jīng):112°49′45″~112°53′30″。工業(yè)廣場的位置位于井田中部,采用斜井立井混合開拓方式,主斜井、副立井及風(fēng)井的斷面分別為14m2、14m2、28m2。開拓方案一為主斜井副立井的開拓方案。方案二為雙斜井的開拓方案。經(jīng)過掘進(jìn)量和經(jīng)濟(jì)的比較,所以選擇開拓方案一。開拓方案一劃
2、分為三個采區(qū),礦井達(dá)產(chǎn)時的首采區(qū)定為一采區(qū),工作面長度為200m,推進(jìn)長度為1010m,回采工藝采用后退式、綜合機(jī)械化采煤法,采空區(qū)采用全部跨落法管理頂板。礦井通風(fēng)采用抽出式通風(fēng),礦井總風(fēng)量為72m3/s,通風(fēng)困難時期和容易時期的風(fēng)阻分別為1808.74Pa、657.99pa。通風(fēng)機(jī)的型號為2K56軸流式通風(fēng)機(jī),風(fēng)量范圍為50-200m3/s,風(fēng)壓范圍為400-3000pa。關(guān)鍵詞:礦井開拓;采煤方法;綜合機(jī)械化采煤。52山西大同大學(xué)煤炭工程學(xué)院2014屆本科生畢業(yè)設(shè)計(jì)ABSTRACTThisdesignisforYangqianbaocoal8-1#seam.Thethicknessof
