1、摘 要一般部分针对淮南顾桥矿井进行了井型为1.5 Mt/a的新井设计。顾桥矿井位于安徽省淮南市境内，井田走向长约7.84km，倾向长约3.52km，面积约27.1km2。主采煤层为13-1和11-2煤层，平均厚度分别为4.65 m和3.1 m，平均倾角都为7。井田工业储量为296.97 Mt，可采储量175.13Mt，矿井服务年限为83.4 a。矿井正常涌水量为420 m3/h，最大涌水量为520 m3/h；矿井相对瓦斯涌出量为10.55 m3/t，属高瓦斯矿井。根据井田地质条件，设计采用立井单水平开拓方式，采区带区式布置方式，共划分为6个带区，2个采区，水平标高-790 m。轨道大巷、胶带机
2、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。考虑到本矿井为高瓦斯矿井，故采用中央分列式通风方式。 针对西二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11204工作面进行了采煤工艺设计。该工作面煤层平均厚度为3.1m，平均倾角7，直接顶为粘土砂岩，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144m。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
3、采用一对1t矿车双层四车窄罐笼和一个带平衡锤的1矿车双层四车宽罐笼运料和升降人员。专题部分题目为三软煤巷锚杆支护技术及应用，主要是研究了三软煤巷的一些巷道特征机理分析和锚杆支护技术理论的陈述，并进行了工程实例应用。翻译部分题目为The Development and Application of Electronic Technology to Increase Health, Safety, and Productivity in the South African Coal Mining Industry，主要介绍了南非在煤矿应用电子技术，以及给煤矿的发展带来的好处。关键词：顾桥矿；立井单

Its about 7.84 km on the strike and 3.52 km on the dip, with the 27 km2 total horizontal area. The minable coal seam are
5、 13-1 and 11-2 with an average thickness of 4.65 m and 3.1 m ，the average dip is 7. The proved reserves of this coal mine are 296.97Mt and the minable reserves are 175.13 Mt, with a mine life of 83.4 a. The normal mine inflow is 420 m3/h and the maximum mine inflow is 520 m3/h. The mine gas emission
6、 rate is 10.55 m3/t which can be recognized as high gas mine. Based on the geological condition of the mine, this design uses a vertical shaft single-level development method, then mining district and strip district preparation ,which divided into six bands and two districts, and track roadway, belt
7、 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 center unattached.The design applies strip preparation against the first band of West Two which divided into 7 stirps to
8、tally, and conducted coal conveyance, ventilation, gangue conveyance and electricity designing.The design conducted coal mining technology design against the 11204 face. The coal seam average thickness of this working face is 3.1 m and the average dip is 7, the immediate roof is clay sand stone and
9、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 in this design and the depth-web is 0.8 m with six working cycles pe
10、r day, and the advance of a working cycle is 4.8 m and the advance is 144 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 16 t skips to lift coal with a balance hammer and the auxiliary shaft
11、 uses a twins narrow1 t four-car double-deck cage and a wide 1t four-car double-deck cage to lift material and personnel transportation.The monographic study entitled Three Soft Coal Bed Roadway Bolt Support Technology and Application , It mainly studies some charactors of the Three Soft Coal Bed Ro
12、adway and the presentation of Bolt Support Technique Theory, then conducts the application of the engineering examples.The title of the translated academic paper is The Development and Application of Electronic Technology to Increase Health, Safety, and Productivity in the South African Coal Mining
13、Industry . It mainly Introduces the application of electronic technology in the coal mine in South Africa, as well as to the benefits of the development of coal mines.Keywords: Guqiao coal mine; single-level shaft; band mode; full-height coal caving; center unattached; three soft coal bed roadway; E
