High Productivity —A Question of Shearer Loader Cutting Sequences
K. Nienhaus, A. K. Bayer & H. Haut, Aachen University of Technology, GER
1 Abstract
Recently, the focus in underground longwall coal mining has been on increasing the installed motor power of shearer loaders and armoured face conveyors (AFC), more sophisticated support control systems and longer face length, in order to reduce costs and achieve higher productivity. These efforts have resulted in higher output and previously unseen face advance rates. The trend towards “bigger and better” equipment and layout schemes, however, is rapidly nearing the limitations of technical and economical feasibility. To realise further productivity increases, organisational changes of longwall mining procedures looks like the only reasonable answer. The benefits of opti-mised shearer loader cutting sequences, leading to better performance, are discussed in this paper.中文譯文
高效生產 — 一個關于采煤機截割的次序的問題
1 摘要
目前, 地面下長壁采煤法致力于增加安裝在采煤機和甲板輸送機的電機功率, 以及更先進的支架控制系統和增加工作面長度,以達到減少費用和取得較高的生產效率的目的。這種努力已經造成較高的開支和先前未見過的設備費用增長速度。現在趨向于 "更大和更好" 的儀器和裝備，然而這種趨勢在技術上和費用上的可行性已經達到極限。為了要實現進一步促進生產力的增加，合理、有機地規范長臂采煤法的工序應該是解決提高生產效率問題的唯一的合理答案。在本文中論述了通過合理安排采煤機的截割次序以實現提高采煤工作效率。
2 簡介
傳統上，在地面下長壁采煤法操作方面，采煤機挖掘過程中，使用以下截割次序之一:反方向的或雙方向的循環。除了這兩種主要...
