1、摘要本次設(shè)計新井為雙鴨山礦業(yè)集團嶺東煤礦0.9Mt/a的新井設(shè)計，共有3層設(shè)計可采煤層，平均總厚度為5.93m。設(shè)計嶺東井田的可采儲量為92.511Mt,服務(wù)年限為58.74a,劃分兩個水平開采。井田平均走向長2500m，平均傾斜長2000m，煤層平均傾角12°，屬于緩傾斜煤層。嶺東煤礦采用雙立井的開拓方式，分組集中大巷布置方式。共劃分八個采區(qū)，其中首采區(qū)為1個，達產(chǎn)工作面1個。首采區(qū)為北一采區(qū)，大巷裝車式下部車場，綜合機械化采煤。年工作日為330天，采用“三·八”式工作制，工作面長為190m，每刀截深為0.8m，每日割七刀。主井采用箕斗提升，副井采用罐籠
2、提升。由于嶺東井田傾斜長度較長，且為緩傾斜煤層，以及煤層地質(zhì)條件等因素影響，決定井田內(nèi)全部采用走向長壁開采。關(guān)鍵詞可采儲量采煤工藝走向長壁全套圖紙，加AbstractTheminedesigningthatthenewmineisShuangYaShanCityminingindustryCorp.LingDongcoalminenewof0.9Mt/atimedesignscapital,common3layerofthemdesigningthataveragegeneralthicknessis5.93tiermaycutcoal.Mtdesigni
