答辯組組長(zhǎng) ( 簽字 ) : 年 月 日 摘 要 這次畢業(yè)設(shè)計(jì)我們所做的是神馬煤礦新井設(shè)計(jì)。主要介紹采區(qū)的設(shè)計(jì)、開(kāi)采的技術(shù)和 技巧、采區(qū)巷道布置及回采系統(tǒng)的構(gòu)成以及采區(qū)各峒室的布置和采區(qū)的工作制度。 1. Summary of the mine, this chapter mainly introduces the position, geology and conditions of the coal seam. 2. Mine development. This chapter extrapolates among other areas, reserve, serving limits, working system, spot of the draft, selection of level, further drift of mine, panel division and underground station. 3. Design of mining districts and retreating technology. This chapter explains the general situation of the mining district, technology and techniques of the working face, roadway layout and operation system in the mining district, the design of the mining district station, cave layout and the schedule for drainage and mining in the main mining district. 4. Operational system of the mine, this chapter states transportation, haulage, ventilation and drainage systems of the mine and the selection of equipment used in the system mentioned above. In order to practice and reinforce the wealth of the knowledge learned in the past four years, I try my best to introduce various stateofthearts when respecting the specific situation of Shenma coal mine. For instance, long wall mine on the inclination, long wall mining on the strike with top coal drawing, and among others, drifting and retaining gateways along goaf are preferred in the design. In addition, the design connects operational situation of a mine with a college student’s ability to elementary scientific research. What’s more, it has been pleted with the aid of AutoCAD20xx, which streamlined the design process dramatically and lessened the hardness of drawing significantly. Thanks for Mr. Gaoyongge giving me so much direction, which let me learn much more. I will try my best to study in order to enrich myself in the future. Thank you!
