毕业论文专题题目：岩巷快速施工技术现状与支护趋势

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7.5 km，倾向长约3.5km，面积约27.1km2。主采煤层为13-1和11-2煤层，平均厚度分别为4.8 m和3.2 m，平均倾角都为6°。井田工业储量为318.01 Mt，可采储量188.72 Mt，矿井服务年限为96.8a。矿井正常涌水量为194 m3/h，最大涌水量为230 m3/h；矿井相对瓦斯涌出量为13.215 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，3个采区，水平标高-780 m。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。考虑到本矿井为高瓦斯矿井，故前期采用中央边界式通风方式，后期采用混合式通风方式，并在开采前预掘底板瓦斯抽排巷进行瓦斯提前卸压抽放。
针对一带区进行了准备方式设计。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。带区服务年限7.9年。
对110101工作面进行了采煤工艺设计。该工作面煤层平均厚度为3.2m，平均倾角6°，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的采煤方法。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0.8 m，每天六个循环，循环进尺4.8 m，月推进度144 m。
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16 t箕斗提煤，副井采用一对1.5 t矿车双层四车宽罐笼运料和升降人员。
专题部分题目是《岩巷快速施工技术现状与支护趋势》，经过查阅大量资料和结合国内外现场应用分析，认为发展快速掘进技术对煤矿经济持续增长有着非常大的意义。
翻译部分题目为《Effects of frequency and grouted length on the behavior of guided ultrasonic waves in rock bolts》，实验结果显示其超声导波在锚杆中的衰减和群速度随着频率和锚固长度的变化而变化。

ABSTRACT
The general design is about a 1.5Mt/a new underground mine design of Guqiao coal mine. Guqiao coal mine is located in Huainan, Anhui province. It’s about 7.5 km on the strike and 3.5 km on the dip, with the 22.1 km2 total horizontal area. The minable coal seam are 13-1 and 11-2 with an average thickness of 4.8 m and 3.2m ，the average dip is 6°. The proved reserves of this coal mine are 318.01 Mt and the minable reserves are 188.72 Mt, with a mine life of96.8 a. The normal mine inflow is 194 m3/h and the maximum mine inflow is 230 m3/h. The mine gas emission rate is 13.215 m3/t which can be recognized as high gas mine.
Based on the geological condition of the mine, this design uses vertical shaft single-level development method, both district and strip preparation ,which divided into 6 strips and 3 distrits totally, The level is at -780 m .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 central boundary ventilation in earlier stage and combined ventilation, excaves bottom gas drainage roadway before mining to relief gas pressure in advance.
The design apply strip preparation against the first band of One which divided into 7 stirps totally, and conducted coal conveyance, ventilation, gangue conveyance and electricity designing. It’s life is 7.9 a.
The design conducted coal mining technology design against the 110101 working face. The coal seam average thickness of this working face is 3.2 m and the average dip is 6°, the immediate roof is day sandstone and the main roof is sand stone. The working face apply fully-mechanized long-wall full-height coal caving method, and using double drum shearer cutting coal which cutting 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 working cycles is 4.8 m per day and 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 uses a twins wide 1.5t four-car double-deck cage to lift material and personnel transportation.
Special section entitled 《Rapid Construction of Rock situation and support trends》;, after the access to large amounts of data and analysis of field application at home and abroad, the development of rapid excavation techniques that sustained economic growth in coal mines has a very large significance.
Translation of part of the topic 《Effects of frequency and grouted length on the behavior of guided ultrasonic waves in rock bolts》, Experimental results show that the guided wave attenuation in the Anchorage and the group velocity with frequency, and the anchorage length changes.
