采矿工程(井工)毕业设计(综采放顶煤)摘要由刀豆文库小编整理，希望给你工作、学习、生活带来方便，猜你可能喜欢“综采放顶煤毕业论文”。

摘要

本设计是*****矿2.40Mt/a新井设计。*****矿位于辽宁省沈阳市康平县境内，交通便利。井田走向约为5.664km，倾向约为3.813km，矿井总面积18.9855km2；井田内有1#、2#两层可采煤层，厚度分别为9m、3.5m，煤层平均倾角8°；井田工业储量为316.17Mt，可采储量为220.20Mt，服务年限为66年；矿井正常涌水量为63.9m3/h，瓦斯相对涌出量为1.17 m3/t，属于低瓦斯矿井。

本设计采用立井单水平开拓。主井和副井、风井均位于井田储量中心处，全矿井采用中央并列式通风。采煤方法主要是倾斜长壁综合机械化采煤，采煤工艺采用综采放顶煤。根据煤层的赋存情况，采用集中大巷的布置方式，两条大巷布置在最下煤层的底板岩层中。主井采用箕斗提升，副井采用罐笼提升，运煤采用皮带运输，实现了全矿井的连续运输。全矿划分为五个采区，采区采用后退式开采。

在设计说明书中，系统地阐述了本次设计中的开拓方案，采煤方法的选择以及设备的配置情况，并对不同的方案作了技术经济比较，各项技术决策均有可行的依据，并且附有一定的数据和资料，最终在老师的指导下，并运用平时及课堂上积累的知识，查找有关资料和文献，确保设计出一个安全高效的现代化矿井。

ABSTRACT

The design is the coal mine of *****矿 2.40Mt /a new well.The coal mine of *****矿 located in Fu Xin City, Liaoning Province Fu Xin territory and transportation is convenient.Ida toward approximately is 5.664km and tendency is about 3.813km, the total area of mine is 18.9855km2;Ida can have a two-tier coal layer which thickne, respectively, for the 9m and

3.5m, average coal seam inclination of 8 degrees;Ida reserves for 316.17Mt，recoverable reserves for 220.20Mt, the service life of 66 years;the normal inflow of mine is 63.9m3 / h, relative gas emiion is 1.17 m3 / t and belong to the low gas mine.This design uses a vertical shaft single-level down to open up.The main shaft and auxiliary shaft, air shaft in the Ida reserves at the center of the whole mine, and the mine uses the central parallel ventilation.Mining method is to inclined long-wall mining technology using mechanized coal caving.According to the occurrence of coal seams, using the central roadway layout, two roadways arranged in the bottom seam floor strata.The main shaft skip hoisting the auxiliary shaft cage hoisting coal belt transport, and continuous transport of the whole mine.The whole mine is divided into five mining areas, mining area uses retreat mining.In the design specification, the system described the design of the pioneering program, the choice of mining method and device configuration, and different scenarios were made the basis of technical and economic comparison of the technical decisions are feasible, and accompanied by a certain amount of data and information, and ultimately, under the guidance of teachers, rational use of the knowledge accumulated in the usual cla, find relevant information and documentation to ensure a safe and efficient modern mine.Keywords: single-level vertical shaft development;central parallel;inclined longwall

mining method;Comprehensive Caving
