Finally, the optimal mine laying operational plan is chosen after the plan candidates being ranked by comparing the degrees of identities.(最后通過比較同一度大小，對備選方案進行排序，選取最優的布雷作戰方案。)

To improve operational performance, Qiu set mine to firmly establish a leading cost management awareness, "four serious," the cost of overall strengthening of budget management.(為提高經營實績，邱集礦牢固樹立成本管理領先意識，突出“四嚴”，全面加強成本預算管理。)

It has merit of operational reliability and convenient use, can better realize the visual and intelligent integrated management of mine safety information, and insures mines operate on the safe side.(該系統具有工作可靠，使用方便的優點，能較好地實現煤礦安全信息的可視化和智能化集成管理，為礦井安全可靠運營提供保障。)

The application results show that this system in line with actual production operational requirements of mine hoist, and also have a good practical value.(應用結果表明，該系統符合礦井提升機實際生產運行要求，具有很好的實用價值。)

The paper summarises the operational performance of the interlock System in pit-head equipment at No. 8 shaft of Ping-Ding-Shan Mine Bureau, Henan Province.(本文總結了作者根據河南省平頂山礦務局八礦井口實際情況所設計的一套井口設施聯動閉鎖系統。)
