1、 I 摘 要 本设计矿井为双鸭山矿业集团东荣一矿4.0Mt/a 新井设计，井田内一共有 6 层可采煤层。平均厚度 4.5m，平均倾角 17 ，东荣一矿的工业储量 645.24Mt， 服务年限为 68.5a。 本矿井设计采用双斜井方案开拓，划分两个水平，一个工作面达产。采 用集中大巷布置，大巷采用胶带输送机运输。通风方式采用分区对角式。采 煤方法为走向长壁采煤法，采煤工艺为综合机械化采煤工艺，采空区处理方 法为全部垮落法。采用“四、六”制作业，三班生产，一班检修。 关键词： 新井设计 双斜井开拓 开采水平 综合机械化 全部垮落 法 II Abstract This is a new design

2、 for the mine of Shuangyashan, output per year is4.0Mt/a. There are six workable coal seams in this mining area.The average angle of coal seams is 17 and the average thickness reached 4.5m. The industrial reserves of the mine are645.24 Mt. The length of service is 68.5years. Double inclined shaft de

3、velopment method is used in the degsined, dividing into two mining levels; a work face reaches to the turnout. The big lane in concentration in adoption arranges, the laneway uses therubber belt conveyer, Ventilation manner is divide area ventilation.The working face adopts longwall coal mining meth

4、od and the coal winning technology is full-mechanized mining.Disposition of mined-out areas is all collapsing. The working days in the mine is 330, every day is divided into four classes. Three classes for produce, one class for overhaul. Key Words: Mine design Double inclined shaft development mining level Full-mechanized all collapsing III 目 录 摘 要 I Abstract .
