潘三矿2.4Mta的新井设计.docx

1、摘 要一般部分针对潘三矿进行了井型为2.4Mt/a的新井设计。潘三矿位于安徽省淮南市境内，井田走向长约9.37km，倾向长约5.92km，面积约55.4km2。主采煤层为13-1#煤层，平均倾角58，平均厚度4m。井田工业储量为307.5Mt，可采储量193.4Mt，矿井服务年限为61.9a。矿井正常涌水量为405m3/h，最大涌水量为420m3/h；矿井相对瓦斯涌出量为12.78m3/t，属高瓦斯矿井。根据井田地质条件，设计采用双立井两水平开拓方式，井田采用全采盘区式布置方式，共划分为两个采区，四个盘区，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#煤层底板岩层中。考虑到本矿井

2、为高瓦斯矿井，矿井通风方式采用分区域式通风。 针对东一带区采用了采区准备方式，共划分14个区段工作面，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10，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7个循环，循环进尺5.6m，月推进度168m。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12t箕斗提煤，副井采用一对1.5t矿车双层四车窄罐笼和一个带平衡锤的1.5t矿车双层

3、四车宽罐笼运料和升降人员。专题部分题目为极松散“三软”煤层采场顶板控制技术研究，给出了深井软岩巷道的变形收敛规律，对矿井生产实践具有显著的指导意义。翻译部分题目为Detection of Gases and Collapses in Underground Mines using WSN，主要介绍了现行井工矿中瓦斯和岩层垮落探测的WSN法应用。关键词：潘三矿；双立井；采盘区布置；综采大采高；分区域式；软岩巷道；矿压观测ABSTRACTThe general design is about a 2.4 Mt/a new underground mine design of Pansan coal

4、 mine. Pansan coal mine is located in Huainan, Anhui province. Its about 9.37 km on the strike and 5.92 km on the dip, with the 55.4 km2 total horizontal area. The minable coal seam is 13-1# with an average thickness of 4.0 m and an average dip of 58. The proved reserves of this coal mine are 307.5M

5、t and the minable reserves are 193.4 Mt, with a mine life of 61.9a. The normal mine inflow is 305 m3/h and the maximum mine inflow is 420m3/h. The mine gas emission rate is 12.78m3/t which can be recognized as high gas mine. Based on the geological condition of the mine, this design uses a duel-vert

6、ical 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 airway are all rock roadways, arranged in the floor rock of 13-1# coal seam. Taking into account of the high gas emission, min

7、e 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 preparation against the first band of East One which divided into 14 districts totally, and conducted coal conveyance, ventilation

8、, 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 4.0 m and the average dip is10, the immediate roof is mud stone and the main roof is sand stone. The working face applies f

9、ully 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 in this design and the depth-web is 0.8 m with 7working cycles per day, and the advance of a working cycle is 5.6m and the

10、advance is 168 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 12 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 w

11、ide 1.5t four-car double-deck cage to lift material and personnel transportation.The monographic study entitled Case Study and Research of Deep Soft Rock Pressure Observation, gave the deformation and convergence law of soft rock roadway, which had significant guidance for practical mine production.
