1、河南理工大學采礦工程專業(yè)2011屆畢業(yè)設計義馬煤業(yè)****煤礦120萬噸采礦專項初步設計摘要：****煤礦位于三門峽市內，井田地質條件中等，開采的2-3煤層賦存穩(wěn)定，傾斜角度為9-13゜，井田劃分為四個盤區(qū)，礦井的生產能力為1.20Mt/a，服務年限為59.6a。本礦井設計采用立井單水平上下山的開拓方式，井底車場為立井梭式車場，由于本礦井型為大型礦井，對連續(xù)運輸要求較高，主要采用膠帶輸送機運輸，礦井工作制度為“四六制”，采用走向長壁采煤，綜合機械化放頂煤開采工藝。關鍵詞：采礦專項初步設計；立井；單水平開拓；盤區(qū)式準備；走向長壁；綜合機械化；放頂煤I河南理工大學采礦工程專業(yè)2
