摘 要:由于礦井下綜采工作面的生產環境極其惡劣,且空間局限,大部分礦井工作面溫度高、濕度大、煤灰重、大功率設備多、且工況復雜。工人在工作面近距離操作,遇緊急情況時,人員沒有躲避空間。另外,現場噪音、粉塵等對會工人身體健康帶來損害,迫切需要將工人從高危的生產環境解放出來。因此進行綜采工作面裝備遠程控制技術的研究對于實現煤礦安全高效生產、改善工人勞動環境、降低勞動強度都有著十分重要的現實意義。本課題研究了綜采工作面裝備遠程控制技術,該技術的研究成功實現了煤礦綜采工作面的無人跟機操作、少人值守自動化安全高效生產,實現了綜采成套裝備智能化控制系統核心技術的突破。該技術通過位于井下設備列車或地面調度指揮中心的監控主機及操作臺,結合綜采設備運行數據及工作面視頻系統,對綜采工作面的設備進行遠程啟停控制、自動化生產控制以及人工遠程干預,實現在采煤生產過程中:以采煤機記憶割煤為主,人工遠程干預為輔;以液壓支架跟隨采煤機自動動作為主,人工遠程干預為輔;以綜采運輸設備集中自動化控制為主,就地控制為輔;以綜采設備智能感知為主,視頻監控為輔;即“以工作面自動控制為主,監控中心遠程干預控制為輔”的工作自動化生產模式,實現“無人跟機作業,有人安全值守”的開采理念,在采煤過程中做到工作面少人甚至無人。該技術的研究成功將工人從操作工變成巡檢工,由設備的自動化替代人工勞動,大大降低了工人的勞動強度,將工人從危險的工作面采場解放到相對安全的順槽監控中心(或地面調度指揮中心),在監控中心對設備進行遠程操控,提高了工人的安全系數,提高了原煤產量和煤炭資源回收率,可完全替代進口技術和產品,對我國煤礦裝備制造業有著重要的現實意義。綜采工作面裝備遠程控制技術大幅提升了綜采成套裝備的智能化水平,帶動了我國在煤機裝備自動化、智能化方面的整體技術進步,為建設大型現代化礦井提供了保障,有力的推動了我國煤炭工業的轉型升級。

Equipment remote control technology of Longwall mine face
Abstract:Because of the harsh environment and limited space in the fully mechanized work face of the coal mine, and the operator working in close distance to equipment, there isnt refuge space,in case of emergencies. In addition, the on-site noise and dust also affect workers health. There is an urgent need to freeing workers from the production environment of the high risk. It is of great practical significance to study on remote control technology of fully mechanized equipment for coal mine safety, high efficiency production, labor environment improvement and the labor intensity of workers reduction.In this project, remote control technology of fully mechanized equipment is studied. The successful implementation of the unmanned operation technology of fully mechanized coal make the fewer people attended safe and efficient automation production realized. The breakthrough of core technologies of intelligent control system for fully mechanized coal mining equipment are reached. The monitoring hosts and the console located in underground equipment train or ground scheduling command center can remotely control the work face equipment start-stop, automation production and artificial intervention, combining fully mining equipment run data and the face video system. It is achieved that in normal production process mining machine memory cut coal is mainly performed, artificial remote intervention supplemented;the supporter following mining machine automatically action is mainly performed, artificial remote intervention supplemented.The automation control is mainly performed, local control supplemented; the mechanized equipment IntelliSense is mainly performed, video surveillance supplemented The concept of unmanned following machine operation, man on duty for safe" is achieved, the work face is few man or unmanned in the coal mining process. The success of the technology make workers from operation workers into patrol workers, by equipment of automation alternative artificial labor, greatly reduced has workers of intensity, will workers from dangerous of face mining field liberation to relative security of Shun slot monitoring Center (or ground scheduling command center), in monitoring center on equipment for remote manipulation, improve has workers of safety, improve has coal production and coal resources recovery, effective to reduced resources waste, created has domestic sets equipment mining field unmanned of of precedent.
Key words:Longwall face, remote control, intelligent mining, intelligent sensing, video monitoring, the underground monitoring center
