我的毕业设计说明书 矿务局林南仓矿90万吨新井设计.doc

设计总说明 本设计包括两个部分：一般部分和专题部分。 一般部分为开滦矿务局林南仓矿90万吨新井设计，全篇共分为十个部分：矿井概括及井田地质特征、井田境界及储量、矿井工作制度和设计生产能力及服务年限、井田开拓、采区巷道布置、采煤方法、井下运输、矿井提升、矿井通风与安全和矿井主要经济技术指标。 林南仓矿位于河北省唐山市境内。矿井东西长约为5150m，南北宽约为3000m，面积为1.54×107m2。井田内的主要可采煤层为9煤，该煤层赋存稳定，平均厚度4.5米。倾角平均为27°，为缓斜厚煤层。井田内工业储量9.13×107吨，可采储量8.35×107吨。矿井平均涌水量为380m3/h，相对瓦斯涌出量2.0256m3/t，属于低瓦斯矿井，煤层具有爆炸危险性，有自然发火现象。 林南仓矿年设计生产能力90万t/y，服务年限92年。采用立井两水平开拓，第一水平标高-600m，第二水平标高-900m，。矿井采用单一走向长壁综合机械化采煤法。 矿井布置1个综采工作面保证全矿井的产量，长度170m，煤的运输采用架线式电机车牵引3吨侧卸式矿车运输。矿井的通风方式采用中央分列式通风。 专题部分为薄煤层开采技术的研究，薄煤层开采对我国煤炭事业的影响和提高薄煤层开采率的方法，以及我国薄煤层开采的优秀案例。 This design includes two parts:General part and special subject part . The general part is a new design of Linnancang Mine in Kailuan coal department. The whole article is divided into ten parts totally: the outline of the mine and the mine filed geology, boundary and reserves, the mine work system、 the designed productive capacity and service life , mine exploition,mine methed, transportation of underground, mine lifting, mine ventilation and safety, and the economic and technologic index of the mine. The Linnancang mine filed lies in the Tangshan city of Hebei province. The boundary of the mine filed runs 5.15 km from west to east and 3km from north to south on average. The total area of the mine is about 15.54km2.there are three main available seams:9#, and the total thickness of the seams is4.5m. It is stable belong to fluty inclined, with the average angle 26 degree. The industry reserves of the mine filed are 91.3million tons and the useable reserves are 83.2 million tons. The average flow of the mine is from 380m3/h. It is a low gassy mine. The coal dust have explosion hazard, and the seam has combustion tendency. The productive capacity of Lingnancang mine is 0.9 million tons per year, and it’s service life is 92 years. There are 2 levels in the mine. The fist development level is located at the level of -600m ,the second is –900m .The coal minning method is fully mechanized mining to the strike with sublevel caving
