山能訊(xun) 近日，地處延安的臨(lin)礦集(ji)(ji)團永明礦通(tong)過(guo)現場環環寫實，找(zhao)準制約(yue)高(gao)(gao)效采(cai)煤的難點和癥(zheng)結，打破原有(you)思維定式，在5煤工作面率先(xian)實現單(dan)班(ban)單(dan)面生產，人(ren)均(jun)工效42.06噸/工，同比提高(gao)(gao)41%，人(ren)員減少19人(ren)左右(you)，創效過(guo)千萬元，實現了集(ji)(ji)約(yue)化安全高(gao)(gao)效生產。
他(ta)們大力推(tui)行“三減三提(ti)”和設(she)備升(sheng)級(ji)，自(zi)主創新改(gai)(gai)造單軌吊式(shi)電(dian)纜滑車(che)、皮帶自(zi)移(yi)機(ji)尾、邁(mai)步自(zi)移(yi)式(shi)超前支(zhi)架(jia)、支(zhi)架(jia)增設(she)抬底缸，升(sheng)級(ji)安裝了純凈水處(chu)理(li)與(yu)恒壓(ya)(ya)供水系統，完(wan)成(cheng)了采煤機(ji)更換搖臂、液壓(ya)(ya)支(zhi)架(jia)更換液壓(ya)(ya)元件等一系列設(she)備升(sheng)級(ji)改(gai)(gai)造項目。皮帶負荷率由54.56%提(ti)高(gao)66.54%，設(she)備開機(ji)率由70.1提(ti)高(gao)80%。
采(cai)掘(jue)(jue)先行，設(she)計(ji)為本(ben)。他們對(dui)采(cai)掘(jue)(jue)工(gong)(gong)作面(mian)(mian)(mian)設(she)計(ji)進(jin)(jin)(jin)行優化(hua)，積(ji)極探索沿空(kong)留(liu)巷新模式(shi)，采(cai)用產氣(qi)具(ju)非(fei)爆破預裂切頂沿空(kong)留(liu)巷技(ji)術(shu)，由年(nian)初(chu)4個(ge)(ge)(ge)掘(jue)(jue)進(jin)(jin)(jin)頭降為2個(ge)(ge)(ge)掘(jue)(jue)進(jin)(jin)(jin)頭，每個(ge)(ge)(ge)工(gong)(gong)作面(mian)(mian)(mian)可減(jian)少掘(jue)(jue)進(jin)(jin)(jin)進(jin)(jin)(jin)尺約(yue)900米，減(jian)少施工(gong)(gong)時(shi)間(jian)2.2個(ge)(ge)(ge)月，增加單個(ge)(ge)(ge)工(gong)(gong)作面(mian)(mian)(mian)儲量4.83萬噸(dun)，多(duo)回收煤(mei)炭0.31萬噸(dun)。同時(shi)，延長工(gong)(gong)作面(mian)(mian)(mian)服務時(shi)間(jian)2.1月，每年(nian)減(jian)少工(gong)(gong)作面(mian)(mian)(mian)搬家1次，萬噸(dun)掘(jue)(jue)進(jin)(jin)(jin)率由164.4m/wt降低為82.9m/wt。按(an)照當前煤(mei)炭價格計(ji)算，預計(ji)單個(ge)(ge)(ge)工(gong)(gong)作面(mian)(mian)(mian)可增加直接收益406.3萬元。通過采(cai)掘(jue)(jue)設(she)計(ji)調優與沿空(kong)留(liu)巷新技(ji)術(shu)應用等一(yi)系(xi)列舉措，保障了礦井安全穩定發(fa)展。
針對綜(zong)(zong)采(cai)工(gong)(gong)區職工(gong)(gong)混合(he)編制(zhi)且(qie)對綜(zong)(zong)采(cai)工(gong)(gong)藝生疏的(de)實(shi)(shi)際，該礦(kuang)重(zhong)新進行組合(he)優化(hua)(hua)，充分(fen)利用“師帶徒”“點帶面(mian)”“技(ji)術(shu)比(bi)武”“生產(chan)會(hui)戰(zhan)”等正面(mian)激(ji)勵手(shou)段，將區長(chang)當隊(dui)長(chang)用，隊(dui)長(chang)當班長(chang)用，不斷(duan)提高作業(ye)人員的(de)操作技(ji)能和技(ji)術(shu)力(li)量(liang)(liang)，達到了減人員、減班次(ci)、不減產(chan)量(liang)(liang)的(de)新格局(ju)。實(shi)(shi)現集約化(hua)(hua)生產(chan)后，他們抽(chou)調15人組建專業(ye)化(hua)(hua)隊(dui)伍(wu)，負(fu)責礦(kuang)井(jing)工(gong)(gong)作面(mian)的(de)安裝(zhuang)回(hui)撤和安全生產(chan)標準化(hua)(hua)的(de)整改工(gong)(gong)作，廢除了工(gong)(gong)作面(mian)安撤由外委隊(dui)伍(wu)施工(gong)(gong)的(de)狀況，還創造了16天(tian)(tian)圓滿完成(cheng)(cheng)安撤任務(wu)，比(bi)預期提前4天(tian)(tian)和日(ri)回(hui)撤20架、安裝(zhuang)19架的(de)紀錄。截至目前，該專業(ye)化(hua)(hua)隊(dui)伍(wu)已安全高質量(liang)(liang)完成(cheng)(cheng)礦(kuang)井(jing)工(gong)(gong)作面(mian)安裝(zhuang)5個、回(hui)撤工(gong)(gong)作面(mian)3個的(de)任務(wu)，較原外委安撤施工(gong)(gong)隊(dui)伍(wu)8個工(gong)(gong)作面(mian)，可(ke)創效(xiao)近400萬元。2021年5煤人均工(gong)(gong)效(xiao)42.06噸/工(gong)(gong)，同比(bi)2020年29.8噸/工(gong)(gong)，提高了41%，人員減少了19人左右。
通過“三減(jian)(jian)三提(ti)”,各項(xiang)目實施和安(an)全(quan)生產工作寫實制度，大力推動“機(ji)械(xie)化換(huan)人(ren)(ren)、自動化減(jian)(jian)人(ren)(ren)、提(ti)效減(jian)(jian)人(ren)(ren)”戰略(lve)，預(yu)計全(quan)年(nian)減(jian)(jian)員(yuan)37人(ren)(ren)，實現全(quan)礦井400人(ren)(ren)目標。
