山能訊 近日，地處延安(an)的臨礦集團永明礦通(tong)過現場環環寫實，找準制約(yue)高效采(cai)煤(mei)的難點(dian)和癥結，打破原有(you)思維定式，在(zai)5煤(mei)工作面(mian)率先實現單(dan)班(ban)單(dan)面(mian)生(sheng)(sheng)產，人(ren)均工效42.06噸/工，同(tong)比提高41%，人(ren)員減少19人(ren)左(zuo)右，創效過千萬元(yuan)，實現了集約(yue)化(hua)安(an)全高效生(sheng)(sheng)產。
他們大力推(tui)行“三(san)減三(san)提(ti)”和設(she)備(bei)升(sheng)級(ji)，自(zi)主創新改造(zao)單(dan)軌吊式電纜(lan)滑車、皮(pi)(pi)帶(dai)自(zi)移機尾、邁步自(zi)移式超前支(zhi)架、支(zhi)架增(zeng)設(she)抬底缸(gang)，升(sheng)級(ji)安裝了純(chun)凈水處理與恒壓(ya)供水系(xi)統，完成了采煤(mei)機更換(huan)搖(yao)臂、液(ye)壓(ya)支(zhi)架更換(huan)液(ye)壓(ya)元(yuan)件等一系(xi)列設(she)備(bei)升(sheng)級(ji)改造(zao)項(xiang)目(mu)。皮(pi)(pi)帶(dai)負荷(he)率由(you)54.56%提(ti)高66.54%，設(she)備(bei)開機率由(you)70.1提(ti)高80%。
采掘(jue)先行(xing)，設計(ji)為(wei)本。他們對(dui)采掘(jue)工(gong)(gong)作(zuo)(zuo)面(mian)(mian)(mian)設計(ji)進(jin)行(xing)優化，積極(ji)探索沿空(kong)留(liu)巷新模式(shi)，采用產氣(qi)具非爆破(po)預裂(lie)切頂沿空(kong)留(liu)巷技術，由(you)(you)年(nian)初(chu)4個(ge)掘(jue)進(jin)頭降(jiang)為(wei)2個(ge)掘(jue)進(jin)頭，每個(ge)工(gong)(gong)作(zuo)(zuo)面(mian)(mian)(mian)可(ke)減少掘(jue)進(jin)進(jin)尺(chi)約900米(mi)，減少施工(gong)(gong)時間2.2個(ge)月，增加(jia)單(dan)個(ge)工(gong)(gong)作(zuo)(zuo)面(mian)(mian)(mian)儲量4.83萬(wan)噸，多回(hui)收(shou)煤炭0.31萬(wan)噸。同時，延長工(gong)(gong)作(zuo)(zuo)面(mian)(mian)(mian)服(fu)務時間2.1月，每年(nian)減少工(gong)(gong)作(zuo)(zuo)面(mian)(mian)(mian)搬家(jia)1次，萬(wan)噸掘(jue)進(jin)率由(you)(you)164.4m/wt降(jiang)低為(wei)82.9m/wt。按照當前(qian)煤炭價格(ge)計(ji)算，預計(ji)單(dan)個(ge)工(gong)(gong)作(zuo)(zuo)面(mian)(mian)(mian)可(ke)增加(jia)直接收(shou)益406.3萬(wan)元(yuan)。通(tong)過采掘(jue)設計(ji)調優與沿空(kong)留(liu)巷新技術應(ying)用等(deng)一系列舉措，保障了礦井安全穩定(ding)發(fa)展(zhan)。
針(zhen)對綜(zong)(zong)采(cai)(cai)工(gong)(gong)(gong)區(qu)職工(gong)(gong)(gong)混合編制(zhi)且對綜(zong)(zong)采(cai)(cai)工(gong)(gong)(gong)藝生疏的(de)(de)實際，該礦重新(xin)進(jin)行(xing)組(zu)合優化，充分利(li)用“師帶(dai)徒”“點(dian)帶(dai)面(mian)(mian)(mian)”“技(ji)術比(bi)武”“生產會戰(zhan)”等正面(mian)(mian)(mian)激勵手(shou)段，將區(qu)長當隊長用，隊長當班長用，不斷提高作(zuo)(zuo)業人員的(de)(de)操作(zuo)(zuo)技(ji)能和(he)技(ji)術力量，達到(dao)了(le)減(jian)人員、減(jian)班次、不減(jian)產量的(de)(de)新(xin)格局。實現(xian)集約(yue)化生產后，他們抽(chou)調(diao)15人組(zu)建專業化隊伍(wu)(wu)，負責礦井工(gong)(gong)(gong)作(zuo)(zuo)面(mian)(mian)(mian)的(de)(de)安(an)裝(zhuang)回(hui)撤(che)和(he)安(an)全生產標準化的(de)(de)整(zheng)改(gai)工(gong)(gong)(gong)作(zuo)(zuo)，廢除了(le)工(gong)(gong)(gong)作(zuo)(zuo)面(mian)(mian)(mian)安(an)撤(che)由外委隊伍(wu)(wu)施工(gong)(gong)(gong)的(de)(de)狀況，還創(chuang)(chuang)造了(le)16天(tian)圓滿完成安(an)撤(che)任務(wu)(wu)，比(bi)預(yu)期提前4天(tian)和(he)日回(hui)撤(che)20架(jia)、安(an)裝(zhuang)19架(jia)的(de)(de)紀錄。截至目(mu)前，該專業化隊伍(wu)(wu)已安(an)全高質量完成礦井工(gong)(gong)(gong)作(zuo)(zuo)面(mian)(mian)(mian)安(an)裝(zhuang)5個(ge)、回(hui)撤(che)工(gong)(gong)(gong)作(zuo)(zuo)面(mian)(mian)(mian)3個(ge)的(de)(de)任務(wu)(wu)，較(jiao)原外委安(an)撤(che)施工(gong)(gong)(gong)隊伍(wu)(wu)8個(ge)工(gong)(gong)(gong)作(zuo)(zuo)面(mian)(mian)(mian)，可創(chuang)(chuang)效近400萬元。2021年5煤人均工(gong)(gong)(gong)效42.06噸(dun)(dun)/工(gong)(gong)(gong)，同比(bi)2020年29.8噸(dun)(dun)/工(gong)(gong)(gong)，提高了(le)41%，人員減(jian)少了(le)19人左(zuo)右(you)。
通過(guo)“三減(jian)(jian)三提(ti)”,各項目實(shi)施和安全(quan)生(sheng)產工(gong)作寫實(shi)制度，大力推動(dong)“機械化換(huan)人、自動(dong)化減(jian)(jian)人、提(ti)效減(jian)(jian)人”戰(zhan)略，預(yu)計全(quan)年減(jian)(jian)員37人，實(shi)現全(quan)礦(kuang)井400人目標。
