【正文】 I 摘 要 本設(shè)計(jì)礦井為雞西礦業(yè)集團(tuán)公司 平崗 礦 ,一共有 3 層可采煤層 ,分別為 2 2 38煤層 .煤層總厚度為 米 ,全區(qū)走向長(zhǎng) ,寬 面積 1/3 焦煤 .設(shè)計(jì)井田的可采儲(chǔ)量為。 本礦井設(shè)計(jì)采用雙立井開拓 ,劃分為兩個(gè)水平， 9 個(gè)采區(qū)， 2 個(gè)工作面達(dá)產(chǎn)，達(dá)產(chǎn)采區(qū)個(gè)數(shù)為 2 個(gè)。大巷運(yùn)輸采用 5 噸底卸式礦車運(yùn)輸 ,采煤方法為走向長(zhǎng)壁采煤法 ,采煤工藝為綜合機(jī)械化采煤工藝。頂板處理方法為全部跨落法。 關(guān)鍵詞 ：礦井設(shè)計(jì) 單一走向長(zhǎng)壁 可采儲(chǔ)量 全套圖紙，加 153893706 II Abstract This is a new design has workable coal seams,they are 2 2 38Total thicknes of coal seam mine is long and mine area is coal seam industry trademark is 1/3 coking mine field recoverable resources . This mine pit design uses take the double vertical shalt development the division as two levels,eight pick working face can achieve big lane transporation uses 5tons Bottomdump mine cars to transport,uses long wall mining on the strike to mine coal wining technology is full mechanized coal wining technology, use the caving method for all working faces.
