3、.6 m，日产量2626.28 t。大巷采用带式输送机运煤，辅助运输采用1.5 t固定箱式矿车。主井装备一对9 t箕斗带平衡锤提煤，副井装备一对1.5 t矿车双层单车罐笼担负辅助运输任务。矿井采用中央并列式通风。通风容易时期矿井总需风量4693.8 m3/min，矿井通风总阻力1641 Pa，风阻0.268Ns2/m8，等积孔2.3 m2，矿井通风容易。矿井通风困难时期矿井总风量4693.8 m3/min，矿井通风总阻力1908 Pa，风阻0.3118Ns2/m8，等积孔2.13m2，矿井通风容易。 专题部分题目是张小楼煤矿高温热害现状及防治翻译部分是一篇瓦斯的突出控制技术在澳大利亚的应用的论

4、文，英文原文题目为：Gas content based outburst control technology in Australia。关键词：立井开拓；上下山开采；综采；单巷掘进；中央并列式ABSTRACTThis design contains three parts: the general，the special subject and the translation.The general design is about a 0.9 Mt/a new underground mine design of Zhangxiaolou coal mine.The whole articl

5、e 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 explorer method used in coal mining; 7. Transp

6、ortation 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. Zhangxiaolou coal mine lies in Xuzhou, Jiangsu province. This mine has special railway and is connect to Longhai railway, the traffic is very co

7、nvenient.Its about 5.0 km on the strike and 3.4 km on the dip,with the 15.944 km2 total horizontal area.The minable coal seam of this mine is only 7 with an average thickness of 3.2 m and an average dip of 16.The proved reserves of this coal mine are 71.53 Mt and the minable reserves are 47.23Mt, wi

8、th a mine life of 40.38 a.The geological condition of the mine is relatively simple.The average thickness of topsoil is 87 m.The normal mine inflow is 208 m3/h and the maximum mine inflow is 268 m3/h. The absolutely gas discharge quantity is 10.51 m3/t .It is a lower gassy mine.Its a coal seam liabl

9、e to explosion. The productive capacity of Zhangxiaolou Mine is 0.9 million tons per year，and the service life is 40.38 years.The mine pit uses the vertical shaft single level to add the inside slope development way. Designed first mining district makes use of the method of preparation in mining are

10、a, the length of working face is 180 m, which uses fully-mechanized coal mining technology, and fully caving method to deal with goaf. The working system is “three-eight”,with two teams mining, and the other overhauling. Every mining team makes three working cycle, with six working cycle everyday. A

11、dvance of working cycle is 0.6 m, and quantity of 2626.38ton coal is maked every day. Main roadway makes use of belt conveyor to transport coal resource, and mine car to be assistant transport. Main shaft makes use of skip to transport coal resource, when subsidiary shaft makes use of cage to be ass
