采礦工程畢業設計論文-雙鴨山礦業集團東榮三礦09mta新井設計(已修改)

　

【正文】 I 摘 要 本設計為雙鴨山東榮三礦 ，共有 3 層設計可采煤層，總厚度為 ，煤的工業牌號為 1/3 焦煤。設計井田的可采儲量為 ，服務年限為 57a， 劃分兩個水平開采。 本設計礦井采用雙立井的開拓方式，分組集中大巷及采區石門的大巷布置方式。共劃分 8 個采區，其中首采區 1 個，投產工作面 1 個。本設計采區為南一 上 ，大巷裝車式下部車場，采用中央分列式通風，普通機械化采煤。年工作日為 330d，采用“四 178。 六”式工作制，工作面長為 190m，每刀截深為，每日割 6 刀。 關鍵詞：走向長壁采煤 法、分組集中大巷、立井開拓 全套圖紙，加 153893706 II Abstract The task of this design is to construct a tons new shaft for ShuangYashan Ming Administration. This mine has three mixable Coal Seam, and its average thickness is meters, types of coal seam is 1/3 coking coal. Designed field of mixable capacity is million tons， it can adapt for 57 years, and is divided into two levels. This mine shaft is applied to double in dined shaft development method。 Layout of gating allargando mining district Eros heading。 this level is divided into 8 mining districts and one worked faces. This worked face is South 1 up worked face, rods 330 days every year. Adapt “ foursix” work situation, work face is 190 meters length of circle is , and times is 6 one day. Key words: longwall coal mining method gathering main roadway vertical shaft development III 目 錄 摘 要 ..........................................................................................................................
