朱集煤矿0.45Mta新井设计.docx

1、摘 要一般部分针对淮南朱集矿井进行了井型为0.45Mt/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7.0km，倾向长约3.0km，面积约21km2。主采煤层为11-2#煤层，平均倾角25，平均厚度4m。井田工业储量为37.93Mt，可采储量24.8Mt，矿井服务年限为100.2a。矿井正常涌水量为342m3/h，最大涌水量为462m3/h；矿井相对瓦斯涌出量为10.3m3/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11-2#煤层底板岩层中。考虑到本矿井为

2、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。 针对西二带区采用了带区准备方式，共划分5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11201工作面进行了采煤工艺设计。该工作面煤层平均厚度为1.32m，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，截深0.8m，每天六个循环，循环进尺4.8m，月推进度132m。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。主井采用两套带平衡锤的16t箕斗提煤，副井采用一对1.5t矿

Zhuji coal mine is located in Huainan, Anhui province.

4、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 seam is 11-2# with an average thickness of 1.32 m and an average dip of 3. The proved reserves of this coal mine are 37.93 Mt and the minable reserves are 24.8 Mt, with a mine life of 42.4

5、 a. The normal mine inflow is 342 m3/h and the maximum mine inflow is 462 m3/h. The mine gas emission rate is 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 prep

6、aration ,which divided into eight bands and two districts, and track roadway, belt conveyor roadway and return airway are all rock roadways, arranged in the floor rock of 11-2# coal seam. Taking into account of the high gas emission, mine ventilation method use two diagonal wings ventilation, and ex

7、caves bottom gas drainage roadway before mining to relief gas pressure in advance.The design applies strip preparation 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

8、coal mining technology design against the 11201 face. The coal seam average thickness of this working face is 1.32 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

9、double drum shearer cutting coal which cuts twice each working cycle. Three-Eight working system has been used in this design and the depth-web is 0.8 m with six working cycles per day, and the advance of a working cycle is 4.8 m and the advance is 132 m per month.The monographic study entitled Deep
