大型缓冲沉淀池优化设计分析 大型缓冲沉淀池优化设计分析 -煤矿论文摘要:文章介绍了余吾矿采区排水系统现状，并就利用废旧巷道改造为采区水仓的大型缓冲沉淀池，进行了方案对比和优化设计分析，认为利用废旧巷道临近采区水仓的位置优势，进行采区排水系统的升级改造，技术上可行，经济效益可观。 关键词:废旧巷道;缓冲沉淀池;排水系统;优化设计 目前余吾矿西翼采区水仓主要采用人工清淤方式，清挖时需先将淤煤人工装车，通过绞车将矿车拉到水仓斜巷上口，之后人工推车或者背运淤煤至主运输胶带溜煤眼处，存在工人劳动强度大、清挖周期长、清挖效率低下等问题［1］。近一年来随着东西翼采区开采强度的增加，使得排水系统接近满负荷运行，过快的淤煤速度，导致内外水仓倒换更加紧张，原有的人力清挖方式已不足以满足要求。为了彻底解决以上问题，须尽快对采区排水系统进行优化设计。 1采区排水系统现状 余吾矿西翼采区水仓布置于采区上山下口，其内水仓长59，外水仓长119，水仓总容积19723。采区水泵房内配备5个吸水小井，每个吸水小井分别安装1台155－3×40型卧式离心吸水泵，扬程120，排水量1553。采区5条上山均布置有排水管路，其中主排水管路布置于1号、2号回风大巷中，主要用于相邻一侧采煤工作面排水;胶带上山排水管路接受巷道沿线各掘进工作面大部分排水及冲巷水，辅运上山及进风上山用于沿线低洼点及沉淀池排水;采区所有排水最终汇流至西翼2号回风大巷并进入水仓排水巷。随着采区大巷的延伸以及采掘工作面的增加，多条在掘巷道顶板进入富水区，工作面涌水增多，比如西翼采区1101胶带巷、1105胶带巷及1105回风巷等掘进工作面;同时，部分巷道临近采空区，掘进过程中需对老空区进行探放水，比如1101回风巷及2203回风巷掘进工作面。以上各种因素均导致水仓淤煤过快，给现有排水系统带来考验。 2采区排水方案优化 daily morning exercises or class-break setting-up exercise and discipline inspection and appraisal of public signs;2, daily cleaning and inspection;3, the daily student school appearance, dress, wearing school card check;4, the daily duty guide to the leadership class discipline three rounds.Weekly moral education work:L, the flag raising ceremony and the national flag speech under the flag raising ceremony held on Monday;2, every week a class meeting, the meeting;3, every week two exercises, cleaning and hygiene, behavior norms, attendance situation published cloth appraisal, and the issue of the code of conduct;;4, weekly work week.Monthly moral education work:1, at least once a month, the theme of education activities, to patriotism education, behavior norms of education as the focus, combined with major retreat day.2, the monthly class quantization assessment and class teacher assessment, selection of behavior for the standard model class.Moral education in each term:1, at the end of each semester to form three good student, outstanding student cadres, civilized student.2, at least once a semester, parents will be.,Student etiquette conventionA, the school leavers1, dress neatly to wear sch
