山能訊 近日，地處延安(an)的臨礦集團永明礦通過現場環環寫實，找準制(zhi)約高效(xiao)(xiao)采煤的難(nan)點(dian)和(he)癥結，打破原有思維定式，在5煤工(gong)作面(mian)率(lv)先實現單班(ban)單面(mian)生產(chan)，人均工(gong)效(xiao)(xiao)42.06噸(dun)/工(gong)，同比提高41%，人員減(jian)少(shao)19人左(zuo)右，創效(xiao)(xiao)過千萬元(yuan)，實現了集約化安(an)全高效(xiao)(xiao)生產(chan)。
他們大(da)力推行“三(san)減(jian)三(san)提”和設(she)(she)備升級(ji)，自(zi)主創(chuang)新改造(zao)(zao)單軌吊式電纜滑(hua)車、皮(pi)帶自(zi)移(yi)機尾、邁步自(zi)移(yi)式超前支架、支架增設(she)(she)抬底缸(gang)，升級(ji)安裝了純凈水(shui)處(chu)理與(yu)恒壓(ya)供水(shui)系(xi)(xi)統，完成(cheng)了采煤機更換(huan)搖(yao)臂、液壓(ya)支架更換(huan)液壓(ya)元件等一系(xi)(xi)列設(she)(she)備升級(ji)改造(zao)(zao)項目。皮(pi)帶負荷率由54.56%提高66.54%，設(she)(she)備開機率由70.1提高80%。
采掘(jue)(jue)先行，設(she)計(ji)為本(ben)。他(ta)們對采掘(jue)(jue)工(gong)(gong)作面(mian)(mian)設(she)計(ji)進(jin)(jin)(jin)行優化，積極探索沿空留巷(xiang)新(xin)模式，采用(yong)產氣具非爆破預裂切頂沿空留巷(xiang)技術，由年(nian)初(chu)4個(ge)(ge)掘(jue)(jue)進(jin)(jin)(jin)頭(tou)降(jiang)為2個(ge)(ge)掘(jue)(jue)進(jin)(jin)(jin)頭(tou)，每個(ge)(ge)工(gong)(gong)作面(mian)(mian)可減(jian)少掘(jue)(jue)進(jin)(jin)(jin)進(jin)(jin)(jin)尺約900米，減(jian)少施(shi)工(gong)(gong)時(shi)間2.2個(ge)(ge)月，增加單個(ge)(ge)工(gong)(gong)作面(mian)(mian)儲量4.83萬噸(dun)，多回收煤(mei)炭0.31萬噸(dun)。同(tong)時(shi)，延長工(gong)(gong)作面(mian)(mian)服務時(shi)間2.1月，每年(nian)減(jian)少工(gong)(gong)作面(mian)(mian)搬(ban)家(jia)1次，萬噸(dun)掘(jue)(jue)進(jin)(jin)(jin)率由164.4m/wt降(jiang)低為82.9m/wt。按照(zhao)當(dang)前(qian)煤(mei)炭價格計(ji)算，預計(ji)單個(ge)(ge)工(gong)(gong)作面(mian)(mian)可增加直接收益(yi)406.3萬元。通過采掘(jue)(jue)設(she)計(ji)調優與(yu)沿空留巷(xiang)新(xin)技術應用(yong)等一系(xi)列舉(ju)措，保障了礦(kuang)井(jing)安全穩定發展(zhan)。
針對綜采工(gong)(gong)(gong)(gong)(gong)區(qu)職工(gong)(gong)(gong)(gong)(gong)混合編制且對綜采工(gong)(gong)(gong)(gong)(gong)藝生疏的(de)(de)(de)實際，該礦重(zhong)新進行組合優化(hua)，充分(fen)利用(yong)“師帶(dai)徒”“點帶(dai)面(mian)(mian)”“技術(shu)(shu)比武(wu)”“生產(chan)(chan)會戰”等正面(mian)(mian)激勵(li)手段(duan)，將區(qu)長(chang)當隊(dui)長(chang)用(yong)，隊(dui)長(chang)當班長(chang)用(yong)，不斷提(ti)高作(zuo)(zuo)業人(ren)員(yuan)(yuan)的(de)(de)(de)操作(zuo)(zuo)技能和技術(shu)(shu)力量，達(da)到(dao)了減(jian)(jian)人(ren)員(yuan)(yuan)、減(jian)(jian)班次、不減(jian)(jian)產(chan)(chan)量的(de)(de)(de)新格局。實現集(ji)約(yue)化(hua)生產(chan)(chan)后，他(ta)們抽(chou)調15人(ren)組建專業化(hua)隊(dui)伍(wu)，負責礦井工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)面(mian)(mian)的(de)(de)(de)安(an)(an)(an)(an)(an)裝回撤(che)(che)(che)和安(an)(an)(an)(an)(an)全生產(chan)(chan)標準化(hua)的(de)(de)(de)整改工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)，廢除了工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)面(mian)(mian)安(an)(an)(an)(an)(an)撤(che)(che)(che)由外委(wei)隊(dui)伍(wu)施(shi)工(gong)(gong)(gong)(gong)(gong)的(de)(de)(de)狀況，還創造了16天圓滿完(wan)成安(an)(an)(an)(an)(an)撤(che)(che)(che)任(ren)務，比預期提(ti)前4天和日回撤(che)(che)(che)20架(jia)、安(an)(an)(an)(an)(an)裝19架(jia)的(de)(de)(de)紀錄。截至目前，該專業化(hua)隊(dui)伍(wu)已安(an)(an)(an)(an)(an)全高質量完(wan)成礦井工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)面(mian)(mian)安(an)(an)(an)(an)(an)裝5個(ge)、回撤(che)(che)(che)工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)面(mian)(mian)3個(ge)的(de)(de)(de)任(ren)務，較原(yuan)外委(wei)安(an)(an)(an)(an)(an)撤(che)(che)(che)施(shi)工(gong)(gong)(gong)(gong)(gong)隊(dui)伍(wu)8個(ge)工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)面(mian)(mian)，可(ke)創效近400萬元(yuan)。2021年5煤人(ren)均(jun)工(gong)(gong)(gong)(gong)(gong)效42.06噸/工(gong)(gong)(gong)(gong)(gong)，同比2020年29.8噸/工(gong)(gong)(gong)(gong)(gong)，提(ti)高了41%，人(ren)員(yuan)(yuan)減(jian)(jian)少了19人(ren)左右。
通(tong)過“三(san)減(jian)三(san)提”,各項(xiang)目(mu)實施和安全(quan)生產工作(zuo)寫實制(zhi)度，大力推動(dong)“機械化換(huan)人、自(zi)動(dong)化減(jian)人、提效減(jian)人”戰略(lve)，預(yu)計全(quan)年減(jian)員37人，實現全(quan)礦井400人目(mu)標。
