古书院矿井1.2Mta新井设计.docx

1、摘 要一般部分针对山西古书院矿井进行了井型为1.2Mt/a的新井设计。古书院矿井位于安山西晋城市境内，面积约24km2。主采煤层为15#煤层，平均倾角4，平均厚度3.50m。井田工业储量为105.42Mt，可采储量81.05Mt，矿井服务年限为51.96a。矿井正常涌水量为333.3m3/h，最大涌水量为375m3/h；矿井相对瓦斯涌出量为5m3/t，属低瓦斯矿井。根据井田地质条件，设计采用双立井单水平开拓方式，井田采用全带区式布置方式，共划分为六个带区，轨道大巷布置在岩层中、胶带机大巷和回风大巷皆为煤层大巷。矿井通风方式采用两翼对角式通风。 针对西二带区进行了带区准备方式设计，进行了运煤、通

2、风、运料、排矸、供电系统设计。针对15201工作面进行了采煤工艺设计。该工作面煤层平均厚度为3.50m，平均倾角4，直接顶为泥岩，老顶为砂岩。工作面采用一次采全高综采采煤法。采用双滚筒采煤机割煤，往返一次割两刀。采用“四六制”工作制度，截深0.6m，每天六个循环，循环进尺3.6m，月推进度108m。大巷采用胶带输送机运煤，辅助运输采用无轨胶轮车。主井采用一对12 t双箕斗提煤，副井采用一对3 t矿车双层单车罐笼运料和升降人员。专题部分题目为大采高一次采全高的上覆岩层特性分析，研究了厚煤层大采高综采工作面的采动覆岩活动规律，并对所设计液压支架的适应性进行评价，分析了大采高工作面的上覆岩层关键层结

3、构效应，并进行了上覆岩层破坏特征数值模拟，为工作面顶板控制提供依据。翻译部分题目为Main parameters calculation and structures of pipe belt conveyor，主要介绍了管状带式输送机的参数计算和结构设计。关键词：古书院矿井；带区布置；一次采全高；两翼对角式；关键层；管状带式输送机。ABSTRACTThe general design is a 1.20 Mt/a new underground mine design of Gushuyuan coal mine. Gushuyuan coal mine is located in Jinc

4、heng, Shanxi province. It has a 24 km2 total horizontal area. The minable coal seam is 15# with an average thickness of 3.50 m and an average dip of 4. The proved reserves of this coal mine are 105.42 Mt and the minable reserves are 81.05 Mt, with a mine life of51.96 year. The normal mine inflow is

5、333 m3/h and the maximum mine inflow is 375 m3/h. The mine gas emission rate is 5 m3/t which can be recognized as low gas mine. Based on the geological condition of the mine, this design uses a duel-vertical shaft single-level development method, and full strip preparation ,which divided into 6 band

6、s and track roadway, belt conveyor roadway and return airway are all coal roadways, arranged in the 3# coal seam. mine ventilation method use two diagonal wings ventilation.The design applies strip preparation against the first band of WEST TWO. It conducted coal conveyance, ventilation, gangue conv

7、eyance and electricity designing.The design conducted coal mining technology design against the 15201 face. The coal seam average thickness of this working face is 3.50 m and the average dip is 4, the immediate roof is mud stone and the main roof is sand stone. The working face applies fully mechani

8、zed longwall sublevel caving method, and uses double drum shearer cutting coal which cuts twice each working cycle. Four-six working system has been used in this design and the depth-web is 0.6 m with six working cycles per day, and the advance of a working cycle is 3.6 m and the advance is 118 m pe

9、r month.Main roadway makes use of belt conveyor to transport coal resource, and no track glue wheel car to be assistant transport. The main shaft uses double 12 t skips to lift coal and the auxiliary shaft uses a twins narrow 3 t one-car double-deck cage to lift material and personnel transportation
