山能訊 近(jin)日，地處延安的(de)(de)臨礦集(ji)團永明(ming)礦通過現場環環寫實(shi)，找準制約(yue)高效(xiao)采煤的(de)(de)難點和(he)癥結(jie)，打破原有思維定式，在(zai)5煤工(gong)作面率(lv)先(xian)實(shi)現單(dan)班單(dan)面生(sheng)產(chan)，人均工(gong)效(xiao)42.06噸(dun)/工(gong)，同比(bi)提(ti)高41%，人員減少19人左(zuo)右，創效(xiao)過千萬元(yuan)，實(shi)現了(le)集(ji)約(yue)化安全高效(xiao)生(sheng)產(chan)。
他們大力推行“三減三提”和(he)設備(bei)升(sheng)級(ji)，自(zi)(zi)主創新改造(zao)單軌(gui)吊式電纜滑車(che)、皮帶自(zi)(zi)移(yi)機(ji)尾、邁步自(zi)(zi)移(yi)式超前支架、支架增(zeng)設抬底缸，升(sheng)級(ji)安裝(zhuang)了純(chun)凈水(shui)處(chu)理與(yu)恒壓(ya)供水(shui)系(xi)統，完成了采煤(mei)機(ji)更換搖(yao)臂、液壓(ya)支架更換液壓(ya)元件等一系(xi)列設備(bei)升(sheng)級(ji)改造(zao)項目。皮帶負荷(he)率(lv)由54.56%提高66.54%，設備(bei)開機(ji)率(lv)由70.1提高80%。
采掘先行(xing)，設(she)計(ji)為本。他們對采掘工(gong)(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)設(she)計(ji)進(jin)行(xing)優(you)化，積極探索沿(yan)空留(liu)巷(xiang)新(xin)模式，采用產(chan)氣具非(fei)爆破預(yu)裂(lie)切頂(ding)沿(yan)空留(liu)巷(xiang)技術，由年(nian)初4個掘進(jin)頭降(jiang)為2個掘進(jin)頭，每個工(gong)(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)可減(jian)少(shao)掘進(jin)進(jin)尺(chi)約900米，減(jian)少(shao)施工(gong)(gong)(gong)(gong)時(shi)間2.2個月，增(zeng)加單個工(gong)(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)儲量(liang)4.83萬(wan)(wan)噸(dun)，多回收煤炭0.31萬(wan)(wan)噸(dun)。同(tong)時(shi)，延長工(gong)(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)服(fu)務時(shi)間2.1月，每年(nian)減(jian)少(shao)工(gong)(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)搬家1次(ci)，萬(wan)(wan)噸(dun)掘進(jin)率由164.4m/wt降(jiang)低為82.9m/wt。按照當前煤炭價格計(ji)算，預(yu)計(ji)單個工(gong)(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)可增(zeng)加直接收益(yi)406.3萬(wan)(wan)元。通過采掘設(she)計(ji)調優(you)與沿(yan)空留(liu)巷(xiang)新(xin)技術應用等一系列舉措，保障了礦井安全(quan)穩定發展(zhan)。
針(zhen)對綜采(cai)工(gong)(gong)(gong)(gong)(gong)區職(zhi)工(gong)(gong)(gong)(gong)(gong)混(hun)合編制且對綜采(cai)工(gong)(gong)(gong)(gong)(gong)藝(yi)生疏的(de)(de)(de)(de)(de)實際，該礦(kuang)重新(xin)進行組合優化(hua)(hua)，充(chong)分利用“師帶徒”“點帶面”“技術(shu)比武”“生產(chan)會戰”等正面激勵(li)手段，將區長(chang)當隊(dui)長(chang)用，隊(dui)長(chang)當班長(chang)用，不斷提高(gao)作業(ye)人員的(de)(de)(de)(de)(de)操(cao)作技能和(he)技術(shu)力量，達(da)到了減(jian)(jian)人員、減(jian)(jian)班次(ci)、不減(jian)(jian)產(chan)量的(de)(de)(de)(de)(de)新(xin)格局。實現集約化(hua)(hua)生產(chan)后，他們抽調15人組建專業(ye)化(hua)(hua)隊(dui)伍，負責礦(kuang)井工(gong)(gong)(gong)(gong)(gong)作面的(de)(de)(de)(de)(de)安(an)(an)(an)裝(zhuang)(zhuang)回撤(che)和(he)安(an)(an)(an)全生產(chan)標準(zhun)化(hua)(hua)的(de)(de)(de)(de)(de)整改工(gong)(gong)(gong)(gong)(gong)作，廢除了工(gong)(gong)(gong)(gong)(gong)作面安(an)(an)(an)撤(che)由(you)外委隊(dui)伍施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)的(de)(de)(de)(de)(de)狀況，還創(chuang)造了16天圓滿完(wan)成安(an)(an)(an)撤(che)任務，比預期(qi)提前4天和(he)日回撤(che)20架、安(an)(an)(an)裝(zhuang)(zhuang)19架的(de)(de)(de)(de)(de)紀(ji)錄。截至(zhi)目前，該專業(ye)化(hua)(hua)隊(dui)伍已安(an)(an)(an)全高(gao)質量完(wan)成礦(kuang)井工(gong)(gong)(gong)(gong)(gong)作面安(an)(an)(an)裝(zhuang)(zhuang)5個、回撤(che)工(gong)(gong)(gong)(gong)(gong)作面3個的(de)(de)(de)(de)(de)任務，較原外委安(an)(an)(an)撤(che)施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)隊(dui)伍8個工(gong)(gong)(gong)(gong)(gong)作面，可創(chuang)效近400萬元。2021年5煤人均工(gong)(gong)(gong)(gong)(gong)效42.06噸(dun)/工(gong)(gong)(gong)(gong)(gong)，同比2020年29.8噸(dun)/工(gong)(gong)(gong)(gong)(gong)，提高(gao)了41%，人員減(jian)(jian)少了19人左右。
通過“三減三提”,各項(xiang)目實(shi)(shi)施和安全生產工作寫(xie)實(shi)(shi)制度，大力推動“機械(xie)化換人、自動化減人、提效減人”戰略，預計全年減員37人，實(shi)(shi)現全礦井400人目標。
