他(ta)們大力推行(xing)“三減(jian)三提”和設備(bei)(bei)升(sheng)級，自(zi)(zi)主創新改造(zao)單軌吊(diao)式電纜滑車、皮帶自(zi)(zi)移機(ji)尾、邁步自(zi)(zi)移式超前支(zhi)(zhi)架、支(zhi)(zhi)架增設抬底缸，升(sheng)級安(an)裝了(le)純凈水處(chu)理與恒壓供水系統，完成(cheng)了(le)采煤機(ji)更換搖臂、液壓支(zhi)(zhi)架更換液壓元件等一(yi)系列設備(bei)(bei)升(sheng)級改造(zao)項目。皮帶負荷率由(you)54.56%提高(gao)66.54%，設備(bei)(bei)開機(ji)率由(you)70.1提高(gao)80%。
采掘先(xian)行，設(she)(she)計(ji)(ji)為(wei)(wei)本。他們(men)對(dui)采掘工(gong)(gong)作(zuo)面(mian)設(she)(she)計(ji)(ji)進(jin)(jin)行優化，積極(ji)探索沿空(kong)留(liu)(liu)巷(xiang)新模式(shi)，采用(yong)產氣具非爆(bao)破預裂切頂(ding)沿空(kong)留(liu)(liu)巷(xiang)技(ji)術，由年初4個掘進(jin)(jin)頭(tou)降為(wei)(wei)2個掘進(jin)(jin)頭(tou)，每個工(gong)(gong)作(zuo)面(mian)可減少(shao)掘進(jin)(jin)進(jin)(jin)尺(chi)約900米，減少(shao)施工(gong)(gong)時間(jian)(jian)2.2個月，增(zeng)加單個工(gong)(gong)作(zuo)面(mian)儲量4.83萬噸(dun)，多(duo)回收煤炭0.31萬噸(dun)。同時，延(yan)長(chang)工(gong)(gong)作(zuo)面(mian)服務(wu)時間(jian)(jian)2.1月，每年減少(shao)工(gong)(gong)作(zuo)面(mian)搬家1次(ci)，萬噸(dun)掘進(jin)(jin)率由164.4m/wt降低為(wei)(wei)82.9m/wt。按(an)照當前煤炭價格計(ji)(ji)算，預計(ji)(ji)單個工(gong)(gong)作(zuo)面(mian)可增(zeng)加直接收益406.3萬元。通(tong)過采掘設(she)(she)計(ji)(ji)調優與沿空(kong)留(liu)(liu)巷(xiang)新技(ji)術應用(yong)等一系列舉(ju)措，保障(zhang)了礦井安全穩定發展。
針對綜采工(gong)(gong)區(qu)職工(gong)(gong)混合(he)編(bian)制(zhi)且對綜采工(gong)(gong)藝生(sheng)疏的(de)實際，該礦(kuang)重新(xin)(xin)進(jin)行組(zu)(zu)合(he)優化，充(chong)分利用“師帶(dai)徒”“點(dian)帶(dai)面(mian)”“技術比(bi)(bi)武(wu)”“生(sheng)產會戰”等正面(mian)激(ji)勵手段(duan)，將區(qu)長(chang)當隊(dui)(dui)長(chang)用，隊(dui)(dui)長(chang)當班(ban)長(chang)用，不斷提(ti)高(gao)作(zuo)(zuo)(zuo)業(ye)(ye)人員的(de)操作(zuo)(zuo)(zuo)技能和技術力量(liang)，達到了減人員、減班(ban)次、不減產量(liang)的(de)新(xin)(xin)格局。實現集(ji)約化生(sheng)產后，他們抽調15人組(zu)(zu)建專業(ye)(ye)化隊(dui)(dui)伍(wu)，負責礦(kuang)井工(gong)(gong)作(zuo)(zuo)(zuo)面(mian)的(de)安(an)(an)裝回撤(che)和安(an)(an)全生(sheng)產標(biao)準化的(de)整改工(gong)(gong)作(zuo)(zuo)(zuo)，廢除了工(gong)(gong)作(zuo)(zuo)(zuo)面(mian)安(an)(an)撤(che)由外(wai)委(wei)(wei)隊(dui)(dui)伍(wu)施工(gong)(gong)的(de)狀況，還創(chuang)造(zao)了16天(tian)圓滿完成(cheng)安(an)(an)撤(che)任(ren)務，比(bi)(bi)預期提(ti)前4天(tian)和日(ri)回撤(che)20架、安(an)(an)裝19架的(de)紀(ji)錄。截至目前，該專業(ye)(ye)化隊(dui)(dui)伍(wu)已安(an)(an)全高(gao)質量(liang)完成(cheng)礦(kuang)井工(gong)(gong)作(zuo)(zuo)(zuo)面(mian)安(an)(an)裝5個、回撤(che)工(gong)(gong)作(zuo)(zuo)(zuo)面(mian)3個的(de)任(ren)務，較原外(wai)委(wei)(wei)安(an)(an)撤(che)施工(gong)(gong)隊(dui)(dui)伍(wu)8個工(gong)(gong)作(zuo)(zuo)(zuo)面(mian)，可(ke)創(chuang)效(xiao)近400萬元。2021年(nian)(nian)5煤(mei)人均(jun)工(gong)(gong)效(xiao)42.06噸/工(gong)(gong)，同比(bi)(bi)2020年(nian)(nian)29.8噸/工(gong)(gong)，提(ti)高(gao)了41%，人員減少了19人左右(you)。
通過“三(san)減(jian)三(san)提”,各項目(mu)實(shi)(shi)施和(he)安全生產工作(zuo)寫實(shi)(shi)制度，大力(li)推(tui)動“機械化(hua)換(huan)人、自動化(hua)減(jian)人、提效減(jian)人”戰略，預(yu)計全年減(jian)員37人，實(shi)(shi)現(xian)全礦井400人目(mu)標。
