采礦工程畢業設計論文-龍煤集團鶴崗分公司興山礦12mta新井設計(已修改)

　

【正文】 I 摘 要 本設計新井為鶴崗興山煤礦 ，共有 6層設計可采煤層，平均總厚度為 14m，煤的工業片牌號為 1/3 焦煤。設計井田的可采儲量為 。服務年限為 62a。劃分兩個水平開采。 本設計礦井采用雙立井的開拓方式，集中大巷及采區石門的大巷布置方式。共劃分 12個采區，其中首采區為 1個，投產工作面 1 個，本設計采區為一采區，工作面年工作日為 330 天，采用“三、八”工作制，工作面長為 190m，滾筒截深 ，日進刀數為 6刀。 提升設備為主井采用箕斗提升，副井采用罐籠提升。 關鍵詞 可采 儲量 立井開拓方案 “三、八”工作制 全套圖紙，加 153893706 II III Abstract The task of this design is to construct a tons new shaft for Hegang Xingshan mine has six minable coal seams, and its average thickness is 14 meters, the types of the coal seam is 1/3 coking coal. Designed field of minable capacity is million tons. It can adapt for 62 years, and is divided into two levels. This mine shaft is applied to double indined shaft development method, layout of gathing gallergand mining district cross heading, the level is divided into 6 mining districts and 1 worked faces. This worked face is 1 worked face, works 330 days every year and adapts ―thereeeight‖ work situation, the work face is 190 meters, the length of circle is meters, and the time is 6 one day. Key words Can adopt to keep the quantisty The shaft project expand thereeeight‖ work situation IV 目 錄 摘 要 ............................................................................................................................
