山能(neng)訊 近日，地處延安的臨礦集團(tuan)永明礦通過(guo)現場環(huan)環(huan)寫實(shi)，找準制約高效采煤(mei)的難點和癥結，打破原有(you)思維定式，在(zai)5煤(mei)工作面率(lv)先實(shi)現單班單面生產(chan)，人均工效42.06噸/工，同比(bi)提高41%，人員(yuan)減(jian)少19人左右，創效過(guo)千萬(wan)元，實(shi)現了集約化安全(quan)高效生產(chan)。
他(ta)們大力推行“三減(jian)三提”和(he)設(she)備升(sheng)級(ji)，自主創新改(gai)造單軌吊式(shi)電纜(lan)滑車(che)、皮帶自移(yi)機(ji)(ji)尾、邁步自移(yi)式(shi)超(chao)前支(zhi)架(jia)、支(zhi)架(jia)增(zeng)設(she)抬底缸，升(sheng)級(ji)安裝了(le)純凈水處理與恒壓(ya)供水系統(tong)，完成了(le)采(cai)煤(mei)機(ji)(ji)更換搖臂、液(ye)壓(ya)支(zhi)架(jia)更換液(ye)壓(ya)元(yuan)件等一系列(lie)設(she)備升(sheng)級(ji)改(gai)造項目。皮帶負荷率由(you)54.56%提高66.54%，設(she)備開機(ji)(ji)率由(you)70.1提高80%。
采(cai)掘(jue)(jue)(jue)先行(xing)，設計為本。他們(men)對采(cai)掘(jue)(jue)(jue)工(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)(mian)設計進(jin)行(xing)優化，積極(ji)探索沿空(kong)留(liu)巷(xiang)新模式，采(cai)用產氣具非爆(bao)破預裂切頂(ding)沿空(kong)留(liu)巷(xiang)技術，由年(nian)初4個(ge)掘(jue)(jue)(jue)進(jin)頭(tou)降(jiang)為2個(ge)掘(jue)(jue)(jue)進(jin)頭(tou)，每個(ge)工(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)(mian)可(ke)減(jian)(jian)少(shao)掘(jue)(jue)(jue)進(jin)進(jin)尺約900米，減(jian)(jian)少(shao)施工(gong)(gong)時(shi)間2.2個(ge)月(yue)，增加單個(ge)工(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)(mian)儲量4.83萬(wan)(wan)噸(dun)，多回收(shou)(shou)煤炭0.31萬(wan)(wan)噸(dun)。同時(shi)，延長工(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)(mian)服務時(shi)間2.1月(yue)，每年(nian)減(jian)(jian)少(shao)工(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)(mian)搬家1次，萬(wan)(wan)噸(dun)掘(jue)(jue)(jue)進(jin)率由164.4m/wt降(jiang)低(di)為82.9m/wt。按照當前(qian)煤炭價(jia)格(ge)計算，預計單個(ge)工(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)(mian)可(ke)增加直接收(shou)(shou)益406.3萬(wan)(wan)元。通過采(cai)掘(jue)(jue)(jue)設計調優與沿空(kong)留(liu)巷(xiang)新技術應(ying)用等一系(xi)列舉(ju)措(cuo)，保(bao)障(zhang)了礦井安全穩定發展(zhan)。
針對(dui)綜采(cai)工(gong)(gong)區(qu)職(zhi)工(gong)(gong)混合(he)編制且(qie)對(dui)綜采(cai)工(gong)(gong)藝生疏的(de)(de)(de)實(shi)際，該礦重(zhong)新進行組合(he)優化，充(chong)分利用“師帶徒”“點(dian)帶面(mian)”“技術比武”“生產(chan)會戰”等正面(mian)激勵手段，將(jiang)區(qu)長(chang)當隊(dui)長(chang)用，隊(dui)長(chang)當班長(chang)用，不斷(duan)提高(gao)作業人(ren)(ren)員(yuan)(yuan)的(de)(de)(de)操作技能和技術力量，達到了減(jian)人(ren)(ren)員(yuan)(yuan)、減(jian)班次、不減(jian)產(chan)量的(de)(de)(de)新格(ge)局(ju)。實(shi)現集約化生產(chan)后，他(ta)們抽調(diao)15人(ren)(ren)組建(jian)專業化隊(dui)伍(wu)，負責礦井(jing)工(gong)(gong)作面(mian)的(de)(de)(de)安(an)(an)裝(zhuang)回(hui)撤(che)和安(an)(an)全生產(chan)標準化的(de)(de)(de)整改(gai)工(gong)(gong)作，廢除了工(gong)(gong)作面(mian)安(an)(an)撤(che)由(you)外委隊(dui)伍(wu)施(shi)(shi)工(gong)(gong)的(de)(de)(de)狀況，還(huan)創(chuang)造了16天圓(yuan)滿完成(cheng)安(an)(an)撤(che)任(ren)務，比預期提前4天和日回(hui)撤(che)20架(jia)、安(an)(an)裝(zhuang)19架(jia)的(de)(de)(de)紀(ji)錄。截至目前，該專業化隊(dui)伍(wu)已安(an)(an)全高(gao)質(zhi)量完成(cheng)礦井(jing)工(gong)(gong)作面(mian)安(an)(an)裝(zhuang)5個(ge)、回(hui)撤(che)工(gong)(gong)作面(mian)3個(ge)的(de)(de)(de)任(ren)務，較原外委安(an)(an)撤(che)施(shi)(shi)工(gong)(gong)隊(dui)伍(wu)8個(ge)工(gong)(gong)作面(mian)，可創(chuang)效近400萬(wan)元。2021年5煤人(ren)(ren)均工(gong)(gong)效42.06噸/工(gong)(gong)，同比2020年29.8噸/工(gong)(gong)，提高(gao)了41%，人(ren)(ren)員(yuan)(yuan)減(jian)少了19人(ren)(ren)左右。
通過“三減(jian)三提(ti)”,各項目實(shi)施和(he)安(an)全生(sheng)產工作(zuo)寫實(shi)制(zhi)度，大(da)力推動“機(ji)械化換人、自動化減(jian)人、提(ti)效減(jian)人”戰略，預(yu)計(ji)全年(nian)減(jian)員37人，實(shi)現全礦井400人目標。
