朱集煤矿1.2Mta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1.2 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11-2煤层和13-1煤层，平均倾角25，平均厚度分别为1.32 m和4 m。井田工业储量为144.83 Mt，可采储量118.03 Mt，矿井服务年限为75.66 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，设计采用双立井开拓暗斜井延伸两水平开拓方式，井田采用带区式和盘区式联合布置方式，共划分为四个带区，一个盘区，轨道大巷

2、、胶带机大巷和回风大巷皆为岩石大巷，分别布置在两层煤底板岩层中。考虑到本矿井为高瓦斯矿井，矿井通风方式采用混合式通风，并在开采前预掘底板瓦斯抽排巷进行瓦斯提前卸压抽放。针对北一带区采用了带区准备方式，共划分6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2.5，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0.6 m，每天五个循环，循环进尺3.0 m，月推进度90 m。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。专题部分题目为朱集矿沿空留巷“Y”型通风技术应用，以朱集矿1111（1）运输顺槽底抽巷为例，进行了详实的瓦斯观测数据收集与处理，给出了高瓦斯矿井瓦斯分布和运移规律，对矿井生产实践具有显著的指导意义。翻译部分题目为UNDERGROUND LIGH TING IN COAL mINES，主要介绍了井下照明存在的问题和井下照明工具种类及其发展。关键词：朱集矿井；立井开拓；带区；综采；沿空掘巷；Y型通风ABSTRACTThe general d

4、esign is about a 1.20 Mt/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 3.0 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 11-2#

5、 with an average thickness of 1.32 m. And the average dip of the coal seam is 2.5. The proved reserves of this coal mine are 144.83 Mtandthe , minable reserves are 118.03 Mtandthe, with a mine life of 75.66 a. The normal mine inflow is 342 m3/h, and the maximum mine inflow is 462 m3/h. The mine gas

6、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 and blind incline shaft two-level development method, and full strip preparation ,which divided into four bandsands , one district, and track roa

7、dway, belt conveyor roadway and return airway are all rock roadways, arranged in the floor rock of the two coal seams. Taking into account of the high gas emission, mine ventilation method use combined ventilation ventilation, and excaves bottom gas drainage roadway before mining to relief gas press

8、ure inadvance.The design applies strip preparation against the first band of North One which divided into 6 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

9、 average thickness of this working face is 4.0 m and the average dip is 2.5, 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 drumshearer cutting coal which cuts twice each working cycle

10、. Three-Eight working system has been used in this design and the depth-web is 0.6 m with five working cycles perday,and the advance of a wor king cycle is 3.0 m and the advance is 90 m permonth.Main roadway makes use of belt conveyor to transport coal resource, and battery locomotive to be assistan

11、t transport. The main shaft uses double 16t s kips to lift coal with a balance hammerand. The auxiliary shaft uses a twins narrow 1.5t four-car double-deckcage and a wide 1.5t four-car double-deckcage to lift material and personnel transportation.The monographic study entitled Application of technol

12、ogy about Y type ventilation with roadway along goaf in Zhuji coal mine , the study took 1111(1) bottom gas drainage Roadway of Zhuji mine as an example, conducted a detailed collection and processing to gas observation data, this paper presents the gas distribution and migration rule in a high gas

13、mine, which had significant guidance for practical mine production.The title of the translated academic paper is Underground lighting in coal mines.Keywords: Zhuji coal mine; vertical shaft development; band mode; The full mechanized coal mining; driving roadwayalong goaf; “Y”type ventilation目 录一般部分
