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。一般部分为凉水井煤矿4.0Mt/a新井设计。凉水井煤矿位于陕西省榆林市神木县锦界镇,交通较为便利。井田走向长度约为6.990km,倾向长度约为9.35km,面积约为63.04km2。主采煤层4-2煤的平均厚度为6m,平均倾角为1,地质条件简单。井田工业储量为487.93Mt,可采储量为353.8Mt。矿井设计年生产能力为4.0Mt/a,服务年限为68a。矿井涌水量不大,瓦斯涌出量小,为低瓦斯矿井。井田为斜井单水平开拓。大巷运输采用胶带运输机运煤,辅助运输采用无轨胶轮车设备。矿井通风方式为中央并列式通风。矿井年工作日为330d,工作制度为“
2、三八”制。一般部分共包括10章:1.矿区概述及井田地质特征;2.井田境界和储量;3.矿井工作制度及设计生产能力、服务年限;4.井田开拓;5.准备方式-盘区巷道布置;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。专题部分题目是大采高一次采全高的上覆岩层特性分析。翻译部分主要内容为锚索支护在深井条件下的应用实践,英文题目为:Effects of frequency and grouted length on the behavior of guided ultrasonic waves in rock bolts.ABSTRACTThis desig
3、n includes three parts: the general part, special subject part and translated part. The general part is a 4.0Mt/a new design of Liangshuijing Mine. Liangshuijing Mine lines in Jingjie Town of YuLin City in ShanXi.The traffic of road and railway is very convenience to the mine. The length of the mine
4、field is about 9.35 km ,the width is about 6.99 km,the total area is 63.04km2.The main coal seam is 4-2 coal seam, and its average thickness is 6m.The average angle of the mine is 1 degree.So the geology condition of mining is simple.The industrial reserves of the minefield are 487.93 million tons.
5、The recoverable reserves are 353.8million tons. The designed productive capacity is 4 million tons percent year, and the service life of the mine is 68 years. The inflow of the mine is not large. The amount of gas emission is low and it is a low gas mine.The development form of the mine field is a d
6、ouble level in an inclined well to expand.The belt conveyors transport coal and Auxiliary Transportation is done by Trackless Tyred Vehicle. Ventilation mode is separation regional ventilation.The working system “three-eight” is used in the liangshuijing Mine. It produced 330d/a.The general part inc
7、ludes ten chapters: 1.An outline of the mine field geology; 2.Boundary and the reserves of mine; 3.The service life and working system of mine; 4.development engineering of coalfield; 5.The layout of panels; 6. The method used in coal mining; 7. Transportation of the underground; 8.The lifting of th
