山能訊 近日，地處延(yan)安(an)(an)的臨礦(kuang)集團永(yong)明(ming)礦(kuang)通過現場環(huan)環(huan)寫實，找準制約高(gao)效采煤的難點和癥結(jie)，打破原(yuan)有思維定(ding)式，在5煤工作面(mian)率(lv)先實現單(dan)班單(dan)面(mian)生產，人均(jun)工效42.06噸/工，同比提(ti)高(gao)41%，人員(yuan)減少19人左右，創(chuang)效過千(qian)萬(wan)元，實現了集約化安(an)(an)全高(gao)效生產。
他們大力推(tui)行“三(san)(san)減三(san)(san)提(ti)(ti)”和設備(bei)(bei)升級，自主創新改造(zao)單軌(gui)吊式(shi)(shi)電纜滑車、皮帶(dai)自移機尾、邁步(bu)自移式(shi)(shi)超(chao)前支(zhi)架(jia)、支(zhi)架(jia)增設抬底缸(gang)，升級安裝了純(chun)凈水處理(li)與恒壓供水系統，完成了采(cai)煤機更換搖臂、液壓支(zhi)架(jia)更換液壓元件等一系列設備(bei)(bei)升級改造(zao)項目。皮帶(dai)負荷率(lv)由54.56%提(ti)(ti)高(gao)66.54%，設備(bei)(bei)開機率(lv)由70.1提(ti)(ti)高(gao)80%。
采(cai)掘先行(xing)，設(she)計(ji)(ji)(ji)為本(ben)。他們對采(cai)掘工(gong)(gong)作(zuo)面設(she)計(ji)(ji)(ji)進(jin)(jin)行(xing)優(you)化(hua)，積極探索沿(yan)空(kong)留(liu)巷(xiang)(xiang)新(xin)模式，采(cai)用產氣具(ju)非爆破預裂切頂沿(yan)空(kong)留(liu)巷(xiang)(xiang)技術，由年初(chu)4個(ge)(ge)掘進(jin)(jin)頭降(jiang)為2個(ge)(ge)掘進(jin)(jin)頭，每個(ge)(ge)工(gong)(gong)作(zuo)面可(ke)減(jian)少(shao)掘進(jin)(jin)進(jin)(jin)尺約(yue)900米，減(jian)少(shao)施(shi)工(gong)(gong)時(shi)間(jian)(jian)2.2個(ge)(ge)月(yue)，增(zeng)(zeng)加(jia)單個(ge)(ge)工(gong)(gong)作(zuo)面儲量4.83萬噸，多回(hui)收(shou)煤(mei)炭0.31萬噸。同時(shi)，延長工(gong)(gong)作(zuo)面服務時(shi)間(jian)(jian)2.1月(yue)，每年減(jian)少(shao)工(gong)(gong)作(zuo)面搬家1次，萬噸掘進(jin)(jin)率(lv)由164.4m/wt降(jiang)低(di)為82.9m/wt。按照當前煤(mei)炭價格計(ji)(ji)(ji)算，預計(ji)(ji)(ji)單個(ge)(ge)工(gong)(gong)作(zuo)面可(ke)增(zeng)(zeng)加(jia)直接收(shou)益406.3萬元。通(tong)過采(cai)掘設(she)計(ji)(ji)(ji)調優(you)與沿(yan)空(kong)留(liu)巷(xiang)(xiang)新(xin)技術應(ying)用等一(yi)系(xi)列舉措(cuo)，保障了礦(kuang)井安全穩定發展。
針對綜采工(gong)(gong)(gong)(gong)(gong)區職工(gong)(gong)(gong)(gong)(gong)混(hun)合(he)(he)編(bian)制且對綜采工(gong)(gong)(gong)(gong)(gong)藝生(sheng)疏的(de)實際，該(gai)礦重新進行組合(he)(he)優化(hua)，充分利用“師帶徒”“點帶面”“技(ji)(ji)術比(bi)武”“生(sheng)產(chan)會戰”等正面激勵手段，將區長當隊(dui)長用，隊(dui)長當班長用，不(bu)斷提(ti)高(gao)作(zuo)(zuo)業(ye)人(ren)(ren)員的(de)操作(zuo)(zuo)技(ji)(ji)能和(he)技(ji)(ji)術力(li)量(liang)(liang)，達到了(le)(le)減(jian)(jian)(jian)人(ren)(ren)員、減(jian)(jian)(jian)班次、不(bu)減(jian)(jian)(jian)產(chan)量(liang)(liang)的(de)新格局(ju)。實現(xian)集約(yue)化(hua)生(sheng)產(chan)后，他(ta)們抽調15人(ren)(ren)組建(jian)專業(ye)化(hua)隊(dui)伍，負責礦井工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)面的(de)安(an)(an)(an)裝回(hui)撤(che)和(he)安(an)(an)(an)全(quan)(quan)生(sheng)產(chan)標準化(hua)的(de)整改工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)，廢除了(le)(le)工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)面安(an)(an)(an)撤(che)由外委隊(dui)伍施工(gong)(gong)(gong)(gong)(gong)的(de)狀(zhuang)況，還(huan)創造了(le)(le)16天圓滿完(wan)成安(an)(an)(an)撤(che)任(ren)務，比(bi)預(yu)期提(ti)前4天和(he)日回(hui)撤(che)20架(jia)(jia)、安(an)(an)(an)裝19架(jia)(jia)的(de)紀錄。截至(zhi)目前，該(gai)專業(ye)化(hua)隊(dui)伍已安(an)(an)(an)全(quan)(quan)高(gao)質量(liang)(liang)完(wan)成礦井工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)面安(an)(an)(an)裝5個(ge)、回(hui)撤(che)工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)面3個(ge)的(de)任(ren)務，較原外委安(an)(an)(an)撤(che)施工(gong)(gong)(gong)(gong)(gong)隊(dui)伍8個(ge)工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)面，可創效近(jin)400萬元。2021年5煤人(ren)(ren)均工(gong)(gong)(gong)(gong)(gong)效42.06噸/工(gong)(gong)(gong)(gong)(gong)，同(tong)比(bi)2020年29.8噸/工(gong)(gong)(gong)(gong)(gong)，提(ti)高(gao)了(le)(le)41%，人(ren)(ren)員減(jian)(jian)(jian)少了(le)(le)19人(ren)(ren)左右(you)。
通過“三減(jian)三提”,各項目實(shi)(shi)施(shi)和安全生產(chan)工(gong)作寫實(shi)(shi)制度，大(da)力推動(dong)(dong)“機械化(hua)換人(ren)、自動(dong)(dong)化(hua)減(jian)人(ren)、提效減(jian)人(ren)”戰略，預計全年減(jian)員37人(ren)，實(shi)(shi)現全礦井400人(ren)目標。
