1、摘 要本毕业设计分为三部分：一般部分针对庞庄煤矿张小楼井进行了井型为2.4Mt/a的新井设计。张小楼矿井位于江苏徐州市境内，井田走向长约4.8km，倾向长约3.53km，面积约16.94km2。主采煤层为7号和9号煤层，上部煤层平均倾角25，下部煤层平均倾角4。7号煤层平均厚度10m，9号煤层平均厚度3m。矿井正常涌水量为140m3/h，最大涌水量为160m3/h；矿井相对瓦斯涌出量为6m3/t，绝对瓦斯涌出量为11.32m3/t，属低瓦斯矿井。张小楼井田工业储量为303.42Mt，可采储量220.73Mt，矿井设计生产能力为2.4Mt/a，矿井服务年限为65.7a。根据井田地质条件，设计采用
2、双立井加暗斜井延伸两水平开拓方式，第一水平标高-600m，采用上下山开采，下上采到-900m，第二水平标高为-1130m，-1100m标高以上采用上山开采，此标高以下采用带区开采。井田共划分为六个采区，两个带区，轨道大巷和胶带机大巷皆为岩石大巷，布置在9号煤层底板岩层中。考虑到本矿井为低瓦斯矿井，矿井通风方式采用中央并列式通风。 针对北一采区采用了采区准备方式，共划分5个工作面，并进行了运煤、通风、运料、排矸、供电系统设计。针对7101工作面进行了采煤工艺设计。该工作面煤层平均厚度为10.0m，平均倾角25，直接顶为砂页岩，老顶为砂岩。工作面采用综放。采用双滚筒采煤机割煤，往返一次割两刀。采用
3、“三八制”工作制度，截深0.8m，每天四个循环，循环进尺3.2m，月推进度96m。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。主井采用两对12t长形箕斗提煤，副井采用一对1.5t矿车双层四车加宽罐笼运料和升降人员。专题部分题目为张小楼微震规律分析研究，以张小楼95206工作面和下山区域为背景，进行了详实的微震监测和数据收集与处理，得出了张小楼微震活动规律，对矿井生产实践和防治矿井冲击地压具有显著的指导意义。翻译部分题目为WAVEFORM EFFECT ON PRE-AND POST-FATIGUE PROPERTIES OF SANDSTONE，主要介绍了不同的波形对砂
