七台河精煤集团新建二矿1.8Mta新井设计.doc

摘 要 本设计矿井为七台河矿业集团有限责任公司新建二矿1.80Mt/a新井设计，共有5层可采煤层，煤层平均厚度为1.5m，煤层工业牌号为1/3焦煤。设计井田的可采储量为177.37Mt，服务年限为70.4年。 本设计矿井采用双立井开拓方式，划分两个开采水平。采用集中大巷布置，大巷采用10吨蓄电池式电机车牵引3.0t底卸式矿车运输，采煤方法为走向长壁采煤法，采煤工艺为普通机械化采煤工艺，采空区处理方法为全部垮落法。 提升设备为主井采用箕斗提升，副井采用罐笼提升。 由于井田倾斜长度较大，且为缓倾斜煤层，以及煤层地质条件等因素影响，决定本井田内全部采用倾斜长壁采煤法开采。 关键词：开采水平;可采煤层;开拓方式;走向长壁;可采储量 Abstract This design mineral well as the Qi taihe mineral industry group limited liability company almond flower coal mine a new well designs, having five layers can adopt the coal seam, average and total thickness is 5 metres.The coal seam industry card number is a zhace spirit coal, designing the well farmland can adopt to keep the177.37 Mts of deal, the service time limit is70.4years. This mineral well design adoption a upright well expands the way, dividing the line two mine the level.Adoption cent the set concentrates the big lane arranges, the big lane adopts a storage battery type electrical engineering car leads a bottom unload type mineral car transports, adopting coal method as the alignment long the wall adopts the coal method, adopting coal craft as to synthesize the mechanization adopt the coal craft, adopting empty the area handles method as all falls the method. The main well adoption many rope rub the box promotes, the vice- well adopts the rigid combination a cage promotes. Because the well farmland slant length is bigger, and incline the coal seam for the , and coal seam geology condition etc. factor effects, deciding this well farmland inside the complete adoption slant. key words：the level;workablecoalseam;developmentmethod;;alignment long wall;useable rederves 摘 要 I Abstract II 第 1 章 井田概况及地质特征 1 1.1 井田概况 1 1.1.1 交通位置 1 1.1.2 地形 地势 2 1.1.3 气象 地震 2 1.1.4 水源及电源 2 1.2 地质特征 2 1.2.1 矿区内的地层情况 2 1.2.2 地质构造 3 1.2.3 煤层赋存状况及可采煤层特征 3 1.2.4 岩石性质 厚度特征 5 1.2.6 沼气 煤尘及煤的自燃性 6 1.2.7 煤质 牌号及用途 7 1.3 勘探程度及可靠性 8 第 2 章 井田境界及储量 11 2.1 井田境界 11 2.1.1 井田周边情况 11 2.1.2 确定井田的依据 11 2.1.3 井田境界 11 2.1.4
