采礦工程畢業設計論文-雞西礦業集團小恒山煤礦24mta新井設計(已修改)

　

【正文】 I 摘要 本設計礦井為雞西礦業集團小恒山煤礦 ，本井田內共有可采煤層 5 層 ,分別為 1 18和 23。煤層總厚度為 ，平均厚度 左右。均為１ /３焦煤，主要用于煉焦和工業用煤。井田平均走向長 5000m，平均傾斜長 6300m，煤層賦存深度 +150m～ 700m，主要地質構造為單斜和斷層，煤層平均傾角 10176。，屬緩傾斜煤層。 本設計礦井工業儲量 ，可采儲量 ，服務年限 。由于井田傾斜長度較大，且為緩傾斜煤層，確定采用傾斜長壁后退式 開采，分為3個開采水平，水平標高分別為 20m、 450m 和 600m。均采用上下山開采，工作面全部采用綜合機械化采煤。 關鍵詞 可采儲量 傾斜長壁 綜合機械化采煤 全套圖紙，加 153893706 II Abstract ThisDesign mine pit for Jixi small Mt. Hengshan ore mine pit design. productivity is , in the well field have 5 to be possible to mine well field moves towards long 6300m equally, medium bank long 5000m, the coal bed average inclination angle 10176。, is the easy gradient coal well field is situated at within the boundaries of the Heilongjiang Province Jixi Mt. Hengshan this ore and the Erdao River subore border, west is neighboring with the Mt. Hengshan ore, southwest the Jixi coal field in the reason permanent mountain village, south is apart from Jixi transportation is convenient, has the forest dense railroad to the north, the recent station is the chicken west station, the railroad may lead to each place by way of Jixi to Mudanjiang, the road may lead to the mishan, Jixi and Mudanjiang. Because the well field incline length is big, also is the easy gradient coal bed, as well as factor influences and so on coal bed geological condition, decided in this well field uses pletely inclines long wall mining coal law surface for ordinary mechanized and synthesis mechanization mining coal.
