山阳煤矿3.0Mta新井设计.doc

1、摘 要一般部分针对澄合山阳矿井进行了井型为3.0Mt/a的新井设计。山阳煤矿位于陕西省合阳县境内，井田走向长约12.8km，倾向长约5.5km，面积约70.4km2。主采煤层为5号煤层，倾角315，平均倾角7，平均厚度4.52m。井田工业储量为456.25Mt，可采储量316.98Mt，矿井服务年限为75.5a。矿井正常涌水量为380.60m3/h，最大涌水量为436.69m3/h；矿井相对瓦斯涌出量为2.256m3/t，属低瓦斯矿井。根据井田地质条件，设计采用双立井单水平开拓方式，井田采用带、盘（采）区式布置方式，共划分为六个块段，一个带区，五个采（盘）区，轨道大巷和胶带大巷皆为岩石大巷，布

2、置在五号煤层底板岩层中。 针对西四带区采用了带区准备方式，共划分19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5401工作面进行了采煤工艺设计。该工作面煤层平均厚度为4.52m，平均倾角3，直接顶为泥岩，老顶为细砂岩。工作面采用长壁综采一次采全高采煤法。采用双滚筒采煤机割煤，往返一次割两刀。采用“三八制”工作制度，截深0.8m，每天八个循环，循环进尺0.8m，月推进度192m。大巷采用胶带输送机运煤，辅助运输采用架线电机车牵引固定箱式矿车。主井采用两套带平衡锤的22t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。

3、专题部分题目为采场底板突水机理分析及预测，主要分析了关于采场底板突水的一般机理及影响因素，并总结了如何预测底板突水的方法。翻译部分题目为 Physical simulation of rock burst induced by stress waves，主要介绍了通过仿真模拟应力波对于岩爆的影响。关键词：山阳煤矿；双立井；带区布置；综采大采高；中央并列式ABSTRACTThe general design is about a 3.0 Mt/a new underground mine design of Shanyang coal mine.
