三間房礦3.0Mta新井設計【含CAD圖紙+文檔】,含CAD圖紙+文檔,三間,mta,設計,cad,圖紙,文檔 摘要 三間房礦位于遼寧省鐵嶺市康平縣西北，交通便利。井田走向（東西）長約3.35km，煤層傾向（南北）長約5.1km，井田總面積為17.07km2。主采煤層為1#煤、2#煤，平均傾角為5°，煤層總厚為16m。井田地質條件較為簡單。 井田工業(yè)資源儲量為3.62億噸，礦井可采儲量2.40億噸。礦井設計生產(chǎn)能力為3Mt/a，礦井服務年限為61.6a，涌水量不大，礦井正常涌水量為40m3/h，最大涌水量為55m3/h。礦井瓦斯涌出量不高，為低瓦斯礦井。 井田為立井單水平開拓。大巷采用膠帶輸送機運煤，輔助運輸采用礦車設備。礦井通風為中央并列式通風。 礦井年工作日為330d，工作制度為“四六”制。 一共包括10章：1.井田概況及地質特征；2.井田境界及儲量；3.礦井設計生產(chǎn)能力及服務年限、一般工作制度；4.井田開拓；5.帶區(qū)巷道布置；6.采煤方法；7.建井工期及開采計劃；8.礦井通風；9.礦井運輸與提升；10.礦井排水；11.技術經(jīng)濟指標。 關鍵詞：立井；帶區(qū)；中央并列式；長壁放頂煤采煤法 Abstract Sanjianfang mine lies in, Northwest of Kangping, Tieling City, Liaoning Province, and convenient transportation. The run of the minefield is 3.35km, the width is about 5.1km, well farmland total area of 17.07km2.No.1 and No.2 is the main coal sean, and its dip angle is 5°,total coal seam thickness is 16m.Minefield geological conditions is relatively simple. The proved reserve of minefield is 362 million tons, recoveraThe recoverable reserves is 240 million tons. Mine design production capacity of 3Mt / a,and mine service life of 61.6a.The normal water flow of the mine is 40m3/h and the max flow of the mine is 55m3 / h. The mineral well gas gushes the deal lower ,for low gas mineral well. The well farmland is a single level in vertical shaft development.The coal is transported by the belt conveyer in the main roadway and auxiliary transport tramcar equipment. Mine ventilation for the central parallel ventilation. The working system “four-six” is used in Sanjianfang mine.It produced 300d/year. Including a total of 10 chapters:1.An outline of the mine field geology ;2.Boundary and the reserves of mine; 3.The service life and working system of mine; 4.Development engineering of coalfield;5.The layout of panels ;6.The methed used in coal mining;7. Well construction period and mining plan;8.The ventilation of the mine;9. Mine transportation and ascension 10. Coal mine drainage .11.The economic and technical norms.
