【正文】 r 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 Beipang 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. 1 目 錄 第一章 礦區(qū)概述及井田特征
