1、华北科技学院毕业设计（论文）第 1 页 共 160 页设计总说明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、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。林南仓井田，位于河北省玉田县林南仓附近。矿井东西长约为 7000m，南北宽约为3500m，面积为 19.25km2。井田内的可采煤层为 9 煤、12 煤，其中主采为 9 煤，该煤层赋存稳定，平均厚度 3.50 米。倾角平均为 20，为缓斜厚煤层。井田内工业储量1.76
2、108吨，可采储量 1.33108吨。矿井最大涌水量为 1170m3/h，相对瓦斯涌出量2.02m3/td，属于低瓦斯矿井，煤层有煤尘爆炸危险性和自然发火现象。林南仓矿年设计生产能力 120 万 t/a，服务年限 79.1 年。采用立井三水平开拓，第一水平标高-450m，第二水平标高-750m，第三水平标高-900m。矿井采用单一走向长壁综合机械化采煤法。矿井布置一个综采工作面保证全矿井的产量，长度 180m，煤的运输采用 10t 架线式电机车牵引 3t 固定式矿车运输。矿井的通风方式采用中央边界式通风。专题部分为深部开采矿压与支护技术研究。该文分析了煤矿深井开采矿压控制的几个关键问题，简述了
3、深井矿压特征，防治对策的研究进展。最后指出该领域里令人关注的力学问题。为了适应矿井深部开采入优化巷道布置入手，强化支护技术改革，合理组织施工，进一步提高了单进水平，保证了采区接续，实现了效益最大化。华北科技学院毕业设计（论文）第 2 页 共 160 页The Brief Introduction of the DesignThis design including two parts: general part and special part.The general part is a new design of Lin nan cang Mine in Kailuan Group. It
4、has ten chapters: the outline of the mine and coalfield geology, boundary and reserves, the designed annual production capacity, service life and working area, underground transportation, lifting, ventilation and safety, the economy and technology index of the mine.The Lin nan cang coal field lies i
5、n the YuTian city of Hebei province. The boundary of the mine runs 7.0 km from west to east and 3.5km from north to south on average. The total area of the mine is about 19.25 km2. there are two available seams:9#,12#. They buryed stably and belonging to lesser pitching coal seam, with the average a
6、ngle 20 degree. The industry reserves of the mine are 176 million tons and the useable 133 million tons. The average flow of the mine water is from 1170 m3/h. It is a lower gas mine. The coal dust have explosion hazard, and the seam has self-combustion tendency.The production annual capacity of Lin
7、nancang mine is 1.2 million tons, and its service life is 79.1 years. There are 3 levels in the mine. The first development level located at the -450m, the second is 750m and the third is 900m. The minning method is fully mechanized along the coal bed strike.There is only one working face in the min
8、e. The length of the face is 180m. Coal is transported by the bottomdump mine car which capacity is 3t and dragged by 10 ton accumulator electrical engineering cars. The form of ventilation is the limitrophe to the coalfields center.The main content of the special subject part is Deep pressure and o
9、pen pit miningThis paper analyzes coal mining Wells of pressure control, this paper expounds several key problems of deep pressure characteristic, the research progress of countermeasures. Finally pointed out in this field at mechanical problems. In order to adapt to the mine roadway by deep mining
