采礦工程畢業設計論文-大雁礦業集團一礦15mta新井設計(已修改)

　

【正文】 I摘 要本設計礦井為大雁礦業集團大雁一礦 ，共有可采煤層 4 層，分別為 118 、19 、25 ，煤層總厚度為 米。設計井田的可采儲量 ，服務年限為 年，由于煤層傾角為 9176。屬緩傾斜煤層，所以本礦井設計采用小傾角煤層群反傾斜開拓方式，劃分為 1 個水平，13 個帶區，一個工作面達產，達產時帶區個數為兩個，一個開采，一個準備。大巷運輸采用 10 噸架線式電機車牽引 3 噸底卸式礦車運輸，采用的采煤方法為傾斜長壁采煤法，采煤工藝為綜合機械化采煤工藝。頂板處理方法為全部跨落法。關鍵詞 礦井設計 傾斜長壁采煤法 全部跨落法全套圖紙，加 153893706II IIIAbstractThe mine design Dayan Mining Group for a spot ore Mt / a new mine design. A total coal seam to four layers, namely, 17,18 ,19 ,25 , Total coal thickness of meters. Mine design recoverable reserves of Mt, design service life of years. As seam inclination of 11 176。 is a gently inclined seam, Adviser of the mine design using small angle seam group develop prehensive antitilt, classified as a level of 13 bands, Face up to a production, production of the district brought the number to two, a mining prepared. Roadway transport 10 tons of used FLine traction motor vehicles three tons dump cars transport, The mining method for inclined longwall mining, coal mining technology for integrated mechanized mining technique. Roof approach for the entire crossloading method.
