1、摘 要本设计包括三个部分：一般部分、专题部分和翻译部分。一般部分针对姚桥矿井进行了井型为1.5Mt/a的新井设计。全篇共分为十个部分：1.矿井概况及井田地质特征；2.井田境界和储量；3.矿井生产能力、服务年限及工作制度；4.井田开拓；5.准备方式采区巷道布置；6.采煤方法；7.井下运输；8.矿井提升；9.矿井通风与安全技术；10.矿井基本技术经济指标。姚桥矿井位于江苏省徐州市境内，井田走向长约7.5km，倾向长约3.6km，面积约27km2。主采煤层为7#煤层，平均倾角8.6，平均厚度4.86m。井田工业储量为178.89Mt，可采储量125.28Mt，矿井服务年限为59.66a。矿井正常涌水
2、量为325m3/h，最大涌水量为465m3/h；矿井相对瓦斯涌出量为0.0054m3/t，属低瓦斯矿井,煤尘有爆炸性危险。有自燃发火倾向。根据井田地质条件，设计采用双立井单水平开拓方式，水平标高为-600m。井田采用全带区式布置方式，共划分为5个带区，轨道大巷、胶带机大巷皆为岩石大巷，布置在7#煤层底板岩层中。考虑到本矿井面积较大，矿井通风方式采用两翼对角式通风。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0.6m，每天六个循环，循环进尺3.6m，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
3、采用两套带平衡锤的16t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。专题部分题目为采空区煤炭自燃注浆灭火技术。翻译部分题目为应力波穿越节理时的透反射研究。关键词：姚桥矿井；双立井；带区布置；综采大采高；两翼对角式；煤炭自燃；注浆ABSTRACTThis design contains three parts: the general，the special subject and the translation.The general design is about a 1.50 Mt/a new underground mine desi
4、gn of Yaoqiao coal mine. The whole article is divided into ten parts: 1.An outline of the mine field geology; 2.Boundary and the reserves of mine; 3.The designed productive capacity, service life and working system of mine; 4.development engineering of coalfield; 5.The layout of panels; 6. The explo
5、rer method used in coal mining; 7. Transportation of the underground; 8.The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical norms.Yaoqiao coal mine is located in Xuzhou, Jiangsu province. Its about 7.5 km on the strike and 36 km on th
6、e dip, with the 27 km2 total horizontal area. The minable coal seam is 7# with an average thickness of 4.86 m and an average dip of 8.6. The proved reserves of this coal mine are 178.89 Mt and the minable reserves are 125.28 Mt, with a mine life of 59.66 a. The normal mine inflow is 325 m3/h and the
7、 maximum mine inflow is 465 m3/h. The mine gas emission rate is 0.0054 m3/t which can be recognized as lower gas mine. The coal dust has explosion hazard as well as the self-combustion tendency. Based on the geological condition of the mine, this design uses a duel-vertical shaft single-level develo
8、pment method, The development level is located at the -600m.The coal mine use full strip preparation ,which divided into six bands, track roadway and belt conveyor roadway are all rock roadways, arranged in the floor rock of 7# coal seam. Taking into account of the big area, mine ventilation method
9、use two diagonal wings ventilation,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 0.6 m with six working cyc
10、les per day, and the advance of a working cycle is 3.6 m and the advance is 108 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
11、 shaft 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 title of special subject is “Spontaneous combustion of coal in goaf grouting extinguishing technology”.
