朱集煤矿0.9Mta新井设计【专题国内外无轨胶轮车的运用现状及发展趋势】.docx

1、摘 要一般部分针对淮南朱集矿井进行了井型为0.9 Mt/a的新井设计。朱集矿井位于安徽省淮南市境内，井田走向长约7.0 km，倾向长约3.0 km，面积约21 km2。主采煤层为13-1#煤层，平均倾角25，平均厚度4 m。井田工业储量为113.12 Mt，可采储量53.09 Mt，矿井服务年限为42.1 a。矿井正常涌水量为342 m3/h，最大涌水量为462 m3/h；矿井相对瓦斯涌出量为10.3 m3/t，属高瓦斯矿井。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，共划分为八个带区，两个盘区，轨道大巷、胶带机大巷和回风大巷皆为岩石大巷，布置在13-1#煤层底板

2、岩层中。考虑到本矿井为高瓦斯矿井，矿井通风方式采用两翼对角式通风，并在开采前预掘底板瓦斯抽排巷进行瓦斯提前卸压抽放。 针对东一带区采用了带区准备方式，共划分7个分带工作面，并进行了运煤、通风、运料、排矸、供电系统设计。针对13101工作面进行了采煤工艺设计。该工作面煤层平均厚度为4.0 m，平均倾角3，直接顶为泥岩，老顶为细砂岩。工作面采用长壁综采一次采全高采煤法。采用双滚筒采煤机割煤，往返一次割两刀。采用“三八制”工作制度，两班半生产，半班检修，截深0.8 m，每天5个循环，循环进尺4.0 m，月推进度120 m。大巷采用胶带输送机运煤，辅助运输采用蓄电池式电机车牵引固定箱式矿车。主井采用两

3、套带平衡锤的16 t箕斗提煤，副井采用一对1.5 t矿车双层四车窄罐笼和一个带平衡锤的1.5 t矿车双层四车宽罐笼运料和升降人员。专题部分题目为国内外无轨胶轮车的运用现状及发展趋势，结合在神东矿区、济三矿的运用，介绍了无轨胶轮车的性能特点，运用现状，主要车型，以及国产化进程，最后展望无轨胶轮车的发展趋势。翻译部分题目为A new coal pillars design method in order to enhance safety of the retreat mining in room and pillars mines，主要介绍了一种在利用房柱式开采时，可以提高煤柱安全性的煤柱设计方

Its about 7.0 km on the strike and 3.2 km on the dip, with the 21.0 km2 total horizontal area. The minable coal

5、 seam is 13-1# with an average thickness of 4.0 m and an average dip of 3. The proved reserves of this coal mine are 113.12 Mt and the minable reserves are 53.09 Mt, with a mine life of 42.1 a. The normal mine inflow is 342 m3/h and the maximum mine inflow is 462 m3/h. The mine gas emission rate is

6、10.3 m3/t,which can be recognized as high 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 eight bands and two districts, and track roadway, belt conveyor roadway and return

7、airway are all rock roadways, arranged in the floor rock of 13-1# coal seam. Taking into account of the high gas emission, mine ventilation method use two diagonal wings ventilation, and excaves bottom gas drainage roadway before mining to relief gas pressure in advance.The design applies strip prep

8、aration against the first band of East One which divided into 5 stirps totally, and conducted coal conveyance, ventilation, gangue conveyance and electricity designing. The design conducted coal mining technology design against the 13101 face. The coal seam average thickness of this working face is

9、4.0 m and the average dip is 3, the immediate roof is mud stone and the main roof is sand stone. The working face applies fully mechanized longwall full-height coal caving method, and uses double drum shearer cutting coal which cuts twice each working cycle. Three-Eight working system has been used

10、in this design and the depth-web is 0.8 m with five working cycles per day, and the advance of a working cycle is 4.0 m and the advance is 120 m per month.Main roadway makes use of belt conveyor to transport coal resource, and battery locomotive to be assistant transport. The main shaft uses double

11、16 t skips to lift coal with a balance hammer and the auxiliary shaft uses a twins narrow1.5 t four-car double-deck cage and a wide 1.5 t four-car double-deck cage to lift material and personnel transportation.The project section on the use of the trackless rubber_tyred car at home and abroad presen
