朱集煤矿0.6Mta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0.6Mt/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13-1#煤层，平均倾角25，平均厚度4m。井田工业储量为114.55Mt，可采储量69.47Mt，矿井服务年限为77.1a。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，井田采用井田东翼带区式布置方式，井田西翼盘区式布置方式，共划分为四个带区，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#

2、煤层底板岩层中。考虑到本矿井为高瓦斯矿井，而且为了尽早出煤，矿井通风方式采用混合式通风，前期中央并列式通风，后期两翼对角式通风，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8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4.0m，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，每天四个循环，循环进尺3.2m，月推进度96m。大巷采用胶带输送机运煤，辅助运输采用蓄电池式电机

3、车牵引固定箱式矿车。主井采用两套带平衡锤的8t箕斗提煤，副井采用一对1t矿车双层四车窄罐笼和一个带平衡锤的1t矿车双层四车宽罐笼运料和升降人员。专题部分题目为瓦斯管理的关键技术研究，主要的工作就是研究瓦斯管理的方法，以及改技术的研究。翻译部分题目为NAVIGATION AND CONTROL OF CONTINUOUS MINING SYSTEMS FOR COAL MINING，主要介绍了连续开采系统的远程控制在煤炭开采中的应用。关键词：朱集矿井；双立井；带区布置；综采大采高；中央并列式 ；瓦斯管理。 ABSTRACTThe general design is about a 0.6 Mt/

4、a new underground mine design of Zhuji coal mine. Zhuji coal mine is located in Huainan, Anhui province. 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 13-1# with an average thickness of 4.0 m and an average dip of 3. The prove

5、d reserves of this coal mine are 114.55 Mt and the minable reserves are 69.47 Mt, with a mine life of 77.1 a. The normal mine inflow is 342 m3/h and the maximum mine inflow is 462 m3/h. The mine gas emission rate is 10.3 m3/t which can be recognized as high gas mine. Based on the geological conditio

6、n of the mine, this design uses a duel-vertical shaft single-level development method, and strip preparation in the east ,and Panel preparation in the west which divided into four bands and two districts, and track roadway, belt conveyor roadway and return airway are all rock roadways, arranged in t

7、he floor rock of 13-1# coal seam. Taking into account of the high gas emission, mine ventilation method use mix two ventilationcentral parallel ventilation in the front，diagonal wings ventilation in the late stage, and excaves bottom gas drainage roadway before mining to relief gas pressure in advan

8、ce.The design applies strip preparation against the first band of East One which divided into 8 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 thi

9、ckness of this working face is 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-Eigh

10、t working system has been used in this design and the depth-web is 0.8 m with four working cycles per day, and the advance of a working cycle is 3.2 m and the advance is 96 m per month.Main roadway makes use of belt conveyor to transport coal resource, and battery locomotive to be assistant transpor

11、t. The main shaft uses double 8 t skips to lift coal with a balance hammer and the auxiliary shaft uses a twins narrow 1t four-car double-deck cage and a wide 1t four-car double-deck cage to lift material and personnel transportation.The monographic study entitled Case Study and Research of Deep Sof

12、t Rock Pressure Observation, the study took 1111(1) bottom gas drainage Roadway of Zhuji Mine as an example, conducted a detailed pressure observation data collection and processing, gave the deformation and convergence law of soft rock roadway, which had significant guidance for practical mine prod
