摘要
本设计分三部分:
一般部分针对义马常村矿的地质条件进行了井型为2.4Mt/a的新井设计。常村矿井位于河南省义马市境内,井田走向长约5.0km,倾向长约3.5km,面积约14km2。主采煤层为2-1、2-3煤层,平均倾角10°,2-1平均厚度3.05m, 2-3平均厚度10.63m,合并区平均厚12.48m。矿井正常涌水量为145m3/h,最大涌水量为375m3/h;矿井相对瓦斯涌出量为1.31m3/t,属低瓦斯矿井。
井田工业储量为246.1Mt,可采储量175.5Mt,设计年产量为2.4Mt/a,矿井服务年限为56.24a。
根据井田地质条件,设计采用立井两水平(暗斜井延深)开拓方式,一水平布置在+100m,二水平布置在-100m。井田采用带区式跟采区式布置方式,共划分为4个带区,1个采区,轨道大巷、胶带机大巷和回风大巷皆为岩石大巷,布置在2-3煤层底板岩层中。考虑到本矿井为低瓦斯矿井,且矿井面积较小,矿井通风方式采用中央并列式通风。
大巷采用胶带输送机运煤,辅助运输采用直流架线式电机车牵引固定箱式矿车。主井采用两套两对12t箕斗提煤,副井采用一对带双层四车(1.5t)罐笼,一个平衡锤的双层两车(5t)运料和升降人员。
针对东一带区采用了带区准备方式,共划分12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21105工作面进行了采煤工艺设计。该工作面煤层平均厚度为12.48m,平均倾角10°,直接顶为灰黑色泥岩,伪顶为薄层状细砂岩。工作面采用长壁综合机械化放顶煤采煤法。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4个循环,循环进尺3.2m,月推进度96m。
专题部分题目为《常村煤矿矿震时空分布规律分析》,以常村矿2115掘进工作面与2120综采工作面为背景,进行了采掘过程中矿震规律的研究,通过观测数据收集与处理,得出了该矿矿震在时间与空间的分布规律。这为矿井采掘工作面的安全生产提供了技术支撑。
