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。一般部分为姚桥矿井5Mt/a新井初步设计，共分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、设计生产能力及服务年限；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。一般部分针对徐州姚桥煤矿矿井进行了井型为5Mt/a的新井设计。姚桥矿井位于江苏省徐州市境内，井田走向长约13.70km，倾向长约4.65km，面积约63.7581 km2。主采煤层为7号煤层，平均倾角9，平均厚度9.8m。井田工业储量为654.7Mt，可采储量457
2、.43Mt，矿井服务年限为70.37a。矿井正常涌水量为325m3/h，最大涌水量为465m3/h；瓦斯相对涌出量远远小于10 m3/t，属低瓦斯矿井。根据井田地质条件，设计采用立井单水平开拓方式，井田采用东翼带区西翼采区式布置方式，共划分为4个带区，2个采区，轨道大巷、运输大巷皆为岩石大巷，布置在7号煤层底板岩层中。本矿井为低瓦斯矿井，矿井通风方式采用中央并列式通风。 针对东三带区采用了带区准备方式，共划分13个分带工作面，并进行了运煤、通风、运料、排矸、供电系统设计。针对13101工作面进行了采煤工艺设计。该工作面煤层平均厚度为9.8m，平均倾角9。工作面采用综采放顶煤采煤法。采用双滚筒采
3、煤机割煤，往返一次割两刀。采用“三八制”工作制度，截深0.8m，每天六个循环，循环进尺4.8m，月推进度132m。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32t箕斗提煤，副井采用一对1.5t矿车双层四车窄罐笼和一个带平衡锤的1.5t矿车双层四车宽罐笼运料和升降人员。专题部分题目是浅析深井巷道支护技术。翻译部分题目为sequence optimization in longwall coal mining，主要介绍了Blaso技术在长壁工作面开采数序时候的应用。关键词：姚桥矿井；立井；带区布置；综采放顶煤；中央并列式； ABSTRACTThis

6、n is about a 5 Mt/a new underground mine design of yaoqiao coal mine. yaoqiao coal mine is located in xuzhou, jiangsu province. Its about 13.70 km on the strike and 4.65 km on the dip, with the 63.7581 km2 total horizontal area. The minable coal seam is 7# with an average thickness of 9.8 m and an a
7、verage dip of 9. The proved reserves of this coal mine are 654.7 Mt and the minable reserves are 457.43 Mt, with a mine life of 70.37a. The normal mine inflow is 325 m3/h and the maximum mine inflow is 465 m3/h. gas relative emission in far less than 10 m3 / t, is a low-gas coal mine.Based on to Ida
