3、m,因井田走向大断层将井田分为南北两部分,井田南部为一水平服务范围,井田北部为二水平服务范围。设计首采区采用采区准备方式,工作面长度219 m,采用一次采全高采煤法,全部跨落法处理采空区。矿井采用“三八”制作业,两班生产,一班检修。生产班每班3个循环,日进6个循环,循环进尺0.6 m,日产量3386.4 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。主井装备一套12 t双箕斗带平衡锤提煤,副井装备一对3 t矿车双层单车罐笼带平衡锤担负辅助运输任务。矿井采用中央并列式通风。通风容易时期矿井总需风量6100 m3/min,矿井通风总阻力1347Pa,风阻0.118Ns2/m8,等
4、积孔3.31 m2,矿井通风容易。矿井通风困难时期矿井总风量6100 m3/min,矿井通风总阻力2301 Pa,风阻0.178 Ns2/m8,等积孔2.75m2,矿井通风也较容易。设计矿井的吨煤成本84.3 元/t。专题部分题目是浅谈煤矿冲击矿压的预测预防措施。主要内容包括冲击矿压的机理、预测方法、预防措施及应用举例。翻译部分是一篇关于加拿大采矿业中的气体排放问题的论文,英文原文题目为:Atmospheric emissions in the Canadian Mineral industry关键词:立井;上下山开采;暗斜井延伸;双巷掘进;中央并列式;ABSTRACTThis design
5、can be divided into three sections: general design, monographic study and translation of an academic paper.The general design is about a 1.2 Mt/a new underground mine design of Zhangshuanglou coal mine. Zhangshuanglou coal mine lies in Xuzhou, Jiangsu province. As Peitun railway run across the east
6、part of the mining field connect to Longhai railway, the traffic is very convenient. Its about 6.8 km on the strike and 3.88 km on the dip,with the 31.93 km2 total horizontal area. The minable coal seam of this mine is only 9 with an average thickness of 3.3 m and an average dip of 14. The proved re
7、serves of this coal mine are 117.7 Mt and the minable reserves are 89.22 Mt, with a mine life of 57.3a.The geological condition of the mine is relatively simple. The normal mine inflow is 320 m3/h and the maximum mine inflow is 412 m3/h. It is bituminous coal 44 with low mine gas emission rate and c
8、oal spontaneous combustion tendency, and its a coal seam liable to explosion.Based on the geological condition of the mine, I bring forward four available project in technology. The first is vertical shaft development with two mining levels and the extension of inclined shaft go to -900 m; thr secon
9、d is vertical shaft development with two mining levels and the extension of vertical shaft go to -1000 m; the third is vertical shaft development with two mining levels and the extension of inclined shaft go to -1000 m; the last is vertical shaft development with two mining levels and the extension
10、of vertical shaft go to -750 m. The fourth project is the best comparing with other three project in technology and economy. The first level is at -650 m, The second level is at -750 m, Because a major fault lies in the center of mine field, the mine field is divided into the north section and the s
11、outh section, the south section is one level service scope, and the north section is two level service scope.Designed first mining district makes use of the method of preparation in mining area, the length of working face is 219 m, which uses fully-mechanized coal mining technology, and fully caving
12、 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. Advance of working cycle is 0.6 m, and quantity of 3386.4 ton coal is makedeveryday.Main roadway makes use of
13、 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 assistant transport. In the prophase of mining the mine makes use of centralized ventilation method,when in the ev
14、ening of mining the mine makes use of areas ventilation method. At the easy time of mine ventilation, the total air quantity is6100 m3 per minute, the total mine ventilation resistance is 1347 Pa, the coefficient of resistance is 10118Ns2/m8, equivalent orifice is 3.31 m2. At the difficult time of m
