1、摘 要本设计包括三个部分：一般部分、专题部分和翻译部分。一般部分是潞安矿业集团五阳矿240万t/a新井设计。全篇共分为十个部分：矿区概述及井田地质特征、井田境界和储量、矿井工作制度和设计生产能力及服务年限、井田开拓、准备方式采区巷道布置、采煤方法、井下运输、矿井提升、矿井通风设计和矿井基本经济技术指标。五阳矿位于山西省长治市，矿井总面积约为69.33km2，井田走向平均长8.36km，倾向平均宽8.6km。井田内有3#和15#煤可采，平均厚度为7.4m，煤层赋存稳定，为缓倾斜煤层，倾角515，平均12。井田内工业储量为197.5Mt，可采储量为142.51Mt。矿井正常涌水量400 m3/h，

2、属于低瓦斯矿井，煤尘有爆炸危险，没有自燃发火现象。五阳矿设计年生产能力为240万t/a，服务年限为74.44年。工作制度为“四六”制。矿井的采煤方法为倾向长壁综合机械化放顶煤开采。矿井为两水平开拓。矿井有一对立井：主井主要用于提煤，副井用于提升材料、人员和矸石。开拓水平设置在+580m和+230m。矿井一个工作面达产，采用综放工作面，年生产能力为240万t/a。工作面长度为280m，煤的运输采用轨道运输，辅助运输也采用矿车。矿井通风方式为区域式通风。专题是一篇论文，文章主要阐述了煤巷锚杆支护技术及其在煤矿中的具体应用。翻译部分是将一篇有关煤炭科技的英文翻译成汉语。英文题目是“Why Longw

5、Xi province, The total area of the mine is 69.33 km2. The boundary of the mine field runs 8.36km on north south and 8.6km on west east on average. There is two exploring layer: No.2 and No.15 and the average thickness of the seam is7.4m. It is stable and fluty inclined. It s dip angle is from 5 degr

6、ee to 15 degree, and is 12 degree on average. The normal flow of the mine is 400m3/h. The coal dust has explosion hazard, and the seam hast self-combustion tendency.The productive capacity ofWuYang Mine is 2.4 million tons per year, and its service life is 74.44 years. Only one working system is use

7、d in the mine. The mine has two level. It gets two vertical shafts: the main shaft is for lift coal and the subsidiary is for lift material and personals. The designed development level should be located at the level of +580m and +230mThere is only one working area in the mine. It is used comprehens
