1、本科（函授）毕业设计说明书 I 忻州窑矿忻州窑矿 1414 # #层 层矿井矿井毕业设计毕业设计 摘摘 要要: :本次设计是大同矿区忻州窑矿 14 #煤层。该矿位于大同煤田东北端，距 大同市 17.5Km，距口泉站 5.3Km。井田内有五九公路贯穿，交通方便。 据井田地质资料：该井田煤层厚度为 4.47m，经鉴定为低瓦斯矿井，瓦斯相对 涌出量平均为 2.04m 3/t。煤层有爆炸危险性。煤的自然倾向等级为易自燃。根据 矿井涌水量预测，该矿井正常涌水量为 2300m 3/d。 设计采用斜井煤门单水平开拓方式，共开掘有两个进风井（主斜井、副斜井） 和一个回风井（井田中央石岩庄北回风立井） 。井田共

2、划分有两个盘区，开采煤层 为 14 。 矿井采煤方法为综合机械化开采方式， 综合机械化掘进， 生产区队设置有： 一个综采队和两个机掘队。 矿井达产时的首采工作面位于东带区，该带区划分为 19 个条带，工作面长度 为 150m，推进长度为 2060m，回采顺序采用后退式、回采工艺大采高一次采全厚 综合机械化采煤法，采用“四六制”作业制度。采空区采用全部跨落法管理顶 板。 关键词：矿井开拓、采煤方法、综合机械化采煤 本科（函授）毕业设计说明书 II AbstractAbstract The design is mine in Datong Coal Mining Area Xinzhouyao 1

3、4 # coal seam. Datong Coal mine located in north-east side, from the City 17.5Km, away from the station I Stephen 5.3Km. Mine Highway 59 runs through there and convenient. According to geological data mine: the mine seam thickness of 4.47m, was identified as the low-gas coal mine, coal gas emission

4、on the group average of 2.04m 3/t. The danger of coal explosion. Level of the natural tendency of coal to spontaneous combustion. Mine discharge in accordance with the forecast, the mine water for normal Chung 2300m 3/d. Design uses a single level of Shihmen inclined to open up the way of opening in

5、to the ventilation shaft there are two (main slope, the Deputy inclined) and a return air shaft (Shi Yan Zhuang central return air shaft). Mine were set into two areas, the exploitation of coal for 14 #. Mine mining method for the comprehensive mechanization caving mining methods, mechanized tunneli

6、ng, the production team set up are: a mechanized caving team and two local excavation team. Mine production mining face at the time of the first panel at the East, the plate is divided into 19 bands, face length of 150m, to promote the length of 2060m, the order of the use of retreat mining-type, in single pass coal mining technology of mechanized top coal caving mining Coal Act, the “system 4 6“ operating system. Goaf method make use of all cross-loading roof management. Key wordsKey w
