采礦工程畢業設計論文-雞西礦業集團平崗煤礦240mta新井設計(已修改)

　

【正文】 I 摘 要 本設計礦井為雞西礦業集團平崗煤礦 ，共有 3層可采煤層，分別為 2 2 33，煤層總厚度為 米。本設計井田的可采儲量，設計服務年限為 62 年。本設計采用雙立井開拓方式，劃分為三個水平， 27個采區。首采區為雙翼開采， 2 個工作面達產，達產時采區個數為兩個。采用聯合布置， 2 2 33層單獨開采。大巷運輸采用 5 噸底卸式礦車運輸，采用的采煤方法為走向長壁采煤法，采煤工藝為綜合機械化采煤工藝。頂板處理方法為全部垮落法。 關鍵詞 ：礦井設計； 立井開拓； 走向長壁采煤法 全套圖紙，加 153893706 II III Abstract This is a new design of workable coal seams,they are22, 24, 33.Total thickness of coal seam is meters. this mine field recoverable resource is ,this mine`s life is 62 mine pit design uses take the double vertical shaft development. The dicision is three pick areas,the first pick area is biplane wing working face can achieve ,two pick areas can achieve , 22, 24, 33coal are lonely,.The big lane transportation uses 5 tons Bottomdump min cars to long wall minning on the soriketo minning technology is full mechanisn winning ues the caving method for all working faces. Keyword: The mine pit design。 Vertical shaft development。 The long wall mining on the strike IV 目 錄 摘 要 ..........................................................................................................................
