山能訊(xun) 近日，地處延安的臨(lin)礦集團永明礦通過現場環環寫實，找準制約高(gao)(gao)效(xiao)采煤的難點(dian)和癥結(jie)，打(da)破原有思維定式，在5煤工作面(mian)(mian)率(lv)先實現單班單面(mian)(mian)生產(chan)，人均(jun)工效(xiao)42.06噸(dun)/工，同比提(ti)高(gao)(gao)41%，人員減少19人左右，創效(xiao)過千(qian)萬元，實現了(le)集約化安全高(gao)(gao)效(xiao)生產(chan)。
他們(men)大力推行“三(san)減三(san)提”和設備(bei)升級，自(zi)(zi)(zi)主創(chuang)新(xin)改造單軌吊式(shi)電(dian)纜(lan)滑車(che)、皮帶自(zi)(zi)(zi)移機尾、邁步自(zi)(zi)(zi)移式(shi)超(chao)前(qian)支架(jia)(jia)、支架(jia)(jia)增設抬底缸，升級安(an)裝了(le)純凈水處理與恒壓供(gong)水系統(tong)，完成(cheng)了(le)采煤機更換搖臂、液(ye)壓支架(jia)(jia)更換液(ye)壓元件等一(yi)系列(lie)設備(bei)升級改造項目(mu)。皮帶負荷率由54.56%提高(gao)66.54%，設備(bei)開機率由70.1提高(gao)80%。
采(cai)掘(jue)(jue)先行，設(she)計(ji)為本。他們對(dui)采(cai)掘(jue)(jue)工(gong)作(zuo)(zuo)(zuo)面設(she)計(ji)進(jin)行優(you)化(hua)，積極探索(suo)沿空留巷新模式，采(cai)用產氣具(ju)非爆(bao)破預裂(lie)切頂沿空留巷技(ji)術(shu)，由年(nian)初4個掘(jue)(jue)進(jin)頭降為2個掘(jue)(jue)進(jin)頭，每(mei)個工(gong)作(zuo)(zuo)(zuo)面可(ke)減少掘(jue)(jue)進(jin)進(jin)尺(chi)約900米，減少施工(gong)時間(jian)2.2個月，增(zeng)加(jia)單個工(gong)作(zuo)(zuo)(zuo)面儲量4.83萬噸(dun)，多回收煤(mei)炭0.31萬噸(dun)。同時，延長工(gong)作(zuo)(zuo)(zuo)面服(fu)務(wu)時間(jian)2.1月，每(mei)年(nian)減少工(gong)作(zuo)(zuo)(zuo)面搬家1次，萬噸(dun)掘(jue)(jue)進(jin)率由164.4m/wt降低為82.9m/wt。按照當前煤(mei)炭價(jia)格計(ji)算(suan)，預計(ji)單個工(gong)作(zuo)(zuo)(zuo)面可(ke)增(zeng)加(jia)直接收益406.3萬元。通過采(cai)掘(jue)(jue)設(she)計(ji)調優(you)與沿空留巷新技(ji)術(shu)應用等一系列舉措(cuo)，保障了礦井安全(quan)穩定發(fa)展。
針對綜(zong)采(cai)工(gong)(gong)(gong)(gong)區職工(gong)(gong)(gong)(gong)混(hun)合編制且對綜(zong)采(cai)工(gong)(gong)(gong)(gong)藝生(sheng)疏的實際，該礦(kuang)重(zhong)新(xin)進行組合優化(hua)，充(chong)分利用(yong)(yong)“師帶(dai)徒(tu)”“點帶(dai)面(mian)”“技術比(bi)武”“生(sheng)產(chan)(chan)會戰”等正面(mian)激勵(li)手段，將區長(chang)當隊(dui)長(chang)用(yong)(yong)，隊(dui)長(chang)當班(ban)長(chang)用(yong)(yong)，不斷提高作(zuo)(zuo)業(ye)人(ren)員的操作(zuo)(zuo)技能和技術力(li)量，達到(dao)了減(jian)(jian)人(ren)員、減(jian)(jian)班(ban)次、不減(jian)(jian)產(chan)(chan)量的新(xin)格局。實現集約(yue)化(hua)生(sheng)產(chan)(chan)后，他(ta)們抽(chou)調15人(ren)組建專業(ye)化(hua)隊(dui)伍(wu)(wu)(wu)，負(fu)責礦(kuang)井(jing)工(gong)(gong)(gong)(gong)作(zuo)(zuo)面(mian)的安(an)裝回(hui)撤(che)(che)和安(an)全生(sheng)產(chan)(chan)標準化(hua)的整改工(gong)(gong)(gong)(gong)作(zuo)(zuo)，廢(fei)除(chu)了工(gong)(gong)(gong)(gong)作(zuo)(zuo)面(mian)安(an)撤(che)(che)由外委隊(dui)伍(wu)(wu)(wu)施(shi)工(gong)(gong)(gong)(gong)的狀況，還創(chuang)造了16天(tian)圓(yuan)滿完成安(an)撤(che)(che)任務，比(bi)預(yu)期(qi)提前4天(tian)和日回(hui)撤(che)(che)20架、安(an)裝19架的紀錄。截至目(mu)前，該專業(ye)化(hua)隊(dui)伍(wu)(wu)(wu)已(yi)安(an)全高質量完成礦(kuang)井(jing)工(gong)(gong)(gong)(gong)作(zuo)(zuo)面(mian)安(an)裝5個(ge)(ge)、回(hui)撤(che)(che)工(gong)(gong)(gong)(gong)作(zuo)(zuo)面(mian)3個(ge)(ge)的任務，較原外委安(an)撤(che)(che)施(shi)工(gong)(gong)(gong)(gong)隊(dui)伍(wu)(wu)(wu)8個(ge)(ge)工(gong)(gong)(gong)(gong)作(zuo)(zuo)面(mian)，可創(chuang)效(xiao)近400萬元。2021年(nian)5煤(mei)人(ren)均(jun)工(gong)(gong)(gong)(gong)效(xiao)42.06噸/工(gong)(gong)(gong)(gong)，同比(bi)2020年(nian)29.8噸/工(gong)(gong)(gong)(gong)，提高了41%，人(ren)員減(jian)(jian)少了19人(ren)左右。
通過“三減三提(ti)”,各項目實施和安全生產工作寫實制(zhi)度(du)，大力推動“機械化換人(ren)、自動化減人(ren)、提(ti)效減人(ren)”戰略，預計全年(nian)減員(yuan)37人(ren)，實現全礦井400人(ren)目標。
