【正文】 I / 88摘 要本設計為七臺河新建二礦 Mt/a 的新井設計，共有 3 層設計可采煤層，平均總厚度為 ，煤的工業(yè)片牌號為褐煤。服務年限為 51a，劃分二個水平開采。本設計礦井采用雙立井的開拓方式，分組集中大巷及采區(qū)石門的大巷布置方式。共劃分 4 采區(qū)， ，投產(chǎn)工作面 2 個。本設計采區(qū)為一采區(qū)，石門裝車式下部車場，采用分區(qū)式通風，高檔普采采煤。年工作日為 330 天，采用“四、六”式工作制，工作面長為 150m，每刀進度為 ，每日割六刀。提升設備為主井采用箕斗提升，副井采用罐籠提升。關(guān)鍵詞：可采儲量 采煤工藝 走向長壁 II / 88AbstractThe task of this design is to construct a 60 million tons for dayan three Ming mine has three minable Coal Seam, and its average thickness is meters, types of coal seam is coking coal. It can adapt for 66years, and is divided into two level.This mine shaft is applied to double indined shaft development method。 Layout of gathing gallergand mining district eross heading。 This level is divided into 8 mining districts and 2 worked faces. This worked fece is middle 2 worked face, ords 330 days every year. Adapt “foursix” work situation, work face is 150 meters length of circle is meters, and times is 6 one day.key words：Recoverable reserves The technology of coal miningTrend grows arm III / 88目 錄摘 要
