山能訊 近日，地(di)處延安的臨礦(kuang)集(ji)團永明礦(kuang)通過現場(chang)環環寫(xie)實，找準制(zhi)約高效采(cai)煤的難(nan)點和癥結，打破原有(you)思維定式(shi)，在5煤工(gong)作面率先實現單班單面生(sheng)產，人(ren)均工(gong)效42.06噸/工(gong)，同比提高41%，人(ren)員減少19人(ren)左右，創(chuang)效過千萬元，實現了集(ji)約化安全高效生(sheng)產。
他們大力推(tui)行“三減三提(ti)”和(he)設備升(sheng)級(ji)，自主創新改造單(dan)軌(gui)吊式電纜(lan)滑(hua)車(che)、皮帶自移機尾、邁(mai)步自移式超前支(zhi)架、支(zhi)架增設抬底缸，升(sheng)級(ji)安裝(zhuang)了純凈(jing)水(shui)處(chu)理與恒壓供水(shui)系(xi)統，完成了采煤機更換搖(yao)臂、液(ye)壓支(zhi)架更換液(ye)壓元(yuan)件等(deng)一系(xi)列設備升(sheng)級(ji)改造項目。皮帶負荷率(lv)由54.56%提(ti)高(gao)66.54%，設備開機率(lv)由70.1提(ti)高(gao)80%。
采掘(jue)(jue)(jue)先行(xing)，設計為(wei)本。他(ta)們(men)對采掘(jue)(jue)(jue)工(gong)作(zuo)(zuo)(zuo)面(mian)設計進(jin)(jin)行(xing)優化，積極探索沿(yan)空留巷新模式(shi)，采用(yong)產氣(qi)具非爆破(po)預裂切頂沿(yan)空留巷技術，由年初4個(ge)掘(jue)(jue)(jue)進(jin)(jin)頭降為(wei)2個(ge)掘(jue)(jue)(jue)進(jin)(jin)頭，每個(ge)工(gong)作(zuo)(zuo)(zuo)面(mian)可(ke)減少(shao)掘(jue)(jue)(jue)進(jin)(jin)進(jin)(jin)尺約900米，減少(shao)施工(gong)時(shi)間2.2個(ge)月，增(zeng)加單(dan)個(ge)工(gong)作(zuo)(zuo)(zuo)面(mian)儲(chu)量4.83萬(wan)(wan)噸，多回收煤(mei)炭(tan)0.31萬(wan)(wan)噸。同時(shi)，延(yan)長工(gong)作(zuo)(zuo)(zuo)面(mian)服務時(shi)間2.1月，每年減少(shao)工(gong)作(zuo)(zuo)(zuo)面(mian)搬家1次，萬(wan)(wan)噸掘(jue)(jue)(jue)進(jin)(jin)率由164.4m/wt降低為(wei)82.9m/wt。按照當(dang)前(qian)煤(mei)炭(tan)價格計算，預計單(dan)個(ge)工(gong)作(zuo)(zuo)(zuo)面(mian)可(ke)增(zeng)加直接收益406.3萬(wan)(wan)元。通過采掘(jue)(jue)(jue)設計調優與沿(yan)空留巷新技術應用(yong)等一(yi)系列舉措，保障了礦井安全(quan)穩定發展。
針對綜采工(gong)(gong)(gong)區職工(gong)(gong)(gong)混合(he)編制(zhi)且對綜采工(gong)(gong)(gong)藝生(sheng)疏(shu)的(de)實(shi)際，該礦(kuang)重新進(jin)行(xing)組(zu)(zu)合(he)優化(hua)，充分(fen)利用(yong)“師帶徒(tu)”“點帶面”“技(ji)術比武”“生(sheng)產(chan)會戰”等正面激(ji)勵手段，將區長當(dang)(dang)隊(dui)(dui)(dui)長用(yong)，隊(dui)(dui)(dui)長當(dang)(dang)班長用(yong)，不斷提高(gao)作(zuo)(zuo)業人員的(de)操作(zuo)(zuo)技(ji)能和(he)技(ji)術力量，達(da)到了減人員、減班次(ci)、不減產(chan)量的(de)新格局(ju)。實(shi)現(xian)集(ji)約(yue)化(hua)生(sheng)產(chan)后，他們抽(chou)調15人組(zu)(zu)建專業化(hua)隊(dui)(dui)(dui)伍(wu)，負責礦(kuang)井工(gong)(gong)(gong)作(zuo)(zuo)面的(de)安(an)(an)(an)(an)(an)裝回(hui)撤(che)(che)和(he)安(an)(an)(an)(an)(an)全(quan)生(sheng)產(chan)標準化(hua)的(de)整改(gai)工(gong)(gong)(gong)作(zuo)(zuo)，廢除(chu)了工(gong)(gong)(gong)作(zuo)(zuo)面安(an)(an)(an)(an)(an)撤(che)(che)由外委隊(dui)(dui)(dui)伍(wu)施工(gong)(gong)(gong)的(de)狀況，還創造了16天(tian)圓(yuan)滿(man)完(wan)成(cheng)安(an)(an)(an)(an)(an)撤(che)(che)任(ren)務(wu)，比預期提前4天(tian)和(he)日回(hui)撤(che)(che)20架、安(an)(an)(an)(an)(an)裝19架的(de)紀(ji)錄。截(jie)至目前，該專業化(hua)隊(dui)(dui)(dui)伍(wu)已安(an)(an)(an)(an)(an)全(quan)高(gao)質量完(wan)成(cheng)礦(kuang)井工(gong)(gong)(gong)作(zuo)(zuo)面安(an)(an)(an)(an)(an)裝5個(ge)、回(hui)撤(che)(che)工(gong)(gong)(gong)作(zuo)(zuo)面3個(ge)的(de)任(ren)務(wu)，較原外委安(an)(an)(an)(an)(an)撤(che)(che)施工(gong)(gong)(gong)隊(dui)(dui)(dui)伍(wu)8個(ge)工(gong)(gong)(gong)作(zuo)(zuo)面，可創效近400萬元。2021年5煤人均(jun)工(gong)(gong)(gong)效42.06噸(dun)/工(gong)(gong)(gong)，同比2020年29.8噸(dun)/工(gong)(gong)(gong)，提高(gao)了41%，人員減少了19人左右。
通(tong)過“三減(jian)三提”,各(ge)項目實施(shi)和安全生產工作(zuo)寫實制度，大(da)力推動(dong)“機械化換(huan)人(ren)(ren)、自動(dong)化減(jian)人(ren)(ren)、提效減(jian)人(ren)(ren)”戰略，預計全年減(jian)員(yuan)37人(ren)(ren)，實現全礦井400人(ren)(ren)目標。
