朱集煤矿45万吨新井设计.doc

1、 第X页摘 要一般部分为朱集煤矿矿45万吨新井初步设计。朱集矿井位于安徽省淮南市境内，井田走向长约7.0km，倾向长约3.0km，面积约21km2。主采煤层为11-2#煤层，平均倾角25，平均厚度1.32m。井田工业储量为37.3Mt，可采储量33.1Mt，矿井服务年限为49.0a。矿井正常涌水量为342m3/h，最大涌水量为462m3/h；矿井相对瓦斯涌出量为10.3m3/t，属高瓦斯矿井。根据井田地质条件，设计采用双立井单水平开拓方式，共划分为五个带区，四个盘区，轨道大巷、胶带机大巷和回风大巷皆为岩石大巷，布置在11-2#煤层底板岩层中。考虑到本矿井为高瓦斯矿井，矿井通风方式采用两翼对角式

2、通风，并在开采前预掘底板瓦斯抽排巷进行瓦斯提前卸压抽放。 针对中央一带区采用了带区准备方式，共划分8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11101工作面进行了采煤工艺设计。该工作面煤层平均厚度为1.32m，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0.6m，每天六个循环，循环进尺3.6m，月推进度108m。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4t箕斗提煤，副井采用一对1.0t矿车单层双车车窄罐笼运料和升降人员。专题

3、部分题目为煤矿冲击地压的预测与防治现状综述，主要研究分析了国内外煤矿的冲击地压分类、发生机理、预测与防治方法现状。翻译部分题目为A method for the design of longwall gateroad roof support，主要介绍了长壁工作面区段平巷顶板支护设计方法。关键词：朱集矿井；双立井；带区布置；两翼对角式；综采采全高AbstractThe general design is about a 0.45 Mt/a new underground mine design of Zhuji coal mine.
