七台河精煤集团公司龙湖三矿1.8Mta新井设计.doc

摘 要 本设计为七台河精煤集团有限公司龙湖三矿1.8Mt/a的新井设计，共有6层设计可采煤层，分别为58#、59#、62C#、63#、65B#、67上#，平均总厚度为15.2m，煤的工业牌号为1/3焦煤。设计井田的可采储量为170.814Mt。服务年限为67a。划分两个水平开采，一水平采用倾斜长壁开采，二水平采用走向长壁开采。井田走向长4.5km，平均倾斜宽5.0km，井田面积22.5km2。 本设计矿井采用双立井的开拓方式，集中大巷及带区石门的大巷布置方式。共划分8个带区，投产工作面1个。大巷运输采用SSI1200/2×315胶带运输机运输，采煤工艺为综合机械化采煤工艺，顶板处理方法为沿空留巷法。工作面年工作日为330d，采用“四、六”工作制，工作面长为180m，循环进度为0.8m。 关键词：可采储量 倾斜长壁 采煤工艺 Abstract This is LongHu No3 coal mine of QiTaiHe coal group limited company 1.8Mt/a new mine design. It altogether have 6 coal seams,they are 58#、59#、62C#、63#、65B#、67#,the average total thickness is 15.2m,the coal industry trademark is 1/3 coking coal. The design mine field recoverable reserves is 170.814Mt. It service life is 67a. It have two mine levels. The first level uses long wall mining method along dip, the second uses long wall mining method along strike.The longth of the mine field is 4.5Km, The dipth of the mine field is 5.0 Km, the square meter is 22.5 Km2 . This design mine adopts double vertical shaft and adopt gathering main roadway and strip district cross-cut fashions. It have 8 districts,1 working face goes into production.The main roadway transportation uses SSI1200/2×315 adhesive transport aircraft.The coal mining technology adopt compositive mechanize fashions. Apical plate adopt gob-side entry retaining. The working days of the working face is 330 days every year, Using “four, six”working system.The length of the working face is 180m and the advance of working cycle is 0.8m。 Key words：recoverable reserves long wall mining method along dip Coal minning technology 目 录 摘 要 I Abstract II 绪 论 1 第1章 井田概况及地质特征 2 1.1 井田概况 2 1.1.1 交通位置 2 1.1.2 地形地势 3 1.1.3 河流 气候 温度 雨量 风向 风速 3 1.1.4 地震史 3 1.1.5 现有生产和在建矿井及小窑生产情况 3 1.1.6 水源和电源 4 1.2 地质特征 4 1.2.1 矿区范围内的地层情况 4 1.2.2 井田范围内和附近的主要地质构造 5 1.2.3 煤层赋存状况及可采煤层特征 6 1.2.4 岩石性质及厚度特征 7 1.2.5 井田内的水文地质情况 8 1.2.6 瓦斯和煤尘的爆炸性及煤的自然性 8 1.2.7 煤质 牌号及用途 9 1.3 地质勘探程度及可靠性 10 第2章 井田境界 储量 服务年限 11 2.1 井田境界 11 2.1.1 井田周边状况 11 2.1.2 井田境界确定的依据 11 2
