山能訊 近日，地處(chu)延安(an)的(de)臨礦(kuang)集團永(yong)明礦(kuang)通過(guo)現場環(huan)環(huan)寫實，找準制(zhi)約高效(xiao)采煤(mei)的(de)難點(dian)和(he)癥結，打破原(yuan)有(you)思維定式，在5煤(mei)工作面(mian)(mian)率先實現單(dan)班單(dan)面(mian)(mian)生(sheng)產，人均工效(xiao)42.06噸(dun)/工，同比提高41%，人員(yuan)減少(shao)19人左(zuo)右，創效(xiao)過(guo)千萬元，實現了集約化(hua)安(an)全高效(xiao)生(sheng)產。
他們大力(li)推行“三(san)減三(san)提(ti)”和(he)設(she)備(bei)升級(ji)，自(zi)主創(chuang)新改造(zao)單(dan)軌(gui)吊式電纜滑車、皮(pi)(pi)帶(dai)自(zi)移(yi)(yi)機(ji)尾、邁步(bu)自(zi)移(yi)(yi)式超前(qian)支(zhi)架(jia)、支(zhi)架(jia)增設(she)抬(tai)底缸，升級(ji)安裝了純凈(jing)水(shui)(shui)處理(li)與(yu)恒(heng)壓供水(shui)(shui)系統(tong)，完成了采煤(mei)機(ji)更換(huan)搖臂、液(ye)壓支(zhi)架(jia)更換(huan)液(ye)壓元件(jian)等一系列設(she)備(bei)升級(ji)改造(zao)項目。皮(pi)(pi)帶(dai)負荷率由54.56%提(ti)高66.54%，設(she)備(bei)開機(ji)率由70.1提(ti)高80%。
采(cai)掘(jue)(jue)先行，設計為(wei)(wei)本。他們對采(cai)掘(jue)(jue)工作(zuo)(zuo)面(mian)設計進(jin)行優(you)化，積極探索沿空留巷(xiang)新(xin)模式，采(cai)用產氣具非爆破預(yu)裂切頂(ding)沿空留巷(xiang)技(ji)術(shu)，由(you)(you)年(nian)初4個掘(jue)(jue)進(jin)頭降(jiang)為(wei)(wei)2個掘(jue)(jue)進(jin)頭，每個工作(zuo)(zuo)面(mian)可(ke)減少掘(jue)(jue)進(jin)進(jin)尺約900米，減少施工時(shi)(shi)間2.2個月，增(zeng)加單(dan)個工作(zuo)(zuo)面(mian)儲量(liang)4.83萬噸(dun)，多回收煤炭(tan)0.31萬噸(dun)。同時(shi)(shi)，延長工作(zuo)(zuo)面(mian)服務時(shi)(shi)間2.1月，每年(nian)減少工作(zuo)(zuo)面(mian)搬家1次(ci)，萬噸(dun)掘(jue)(jue)進(jin)率由(you)(you)164.4m/wt降(jiang)低(di)為(wei)(wei)82.9m/wt。按照當(dang)前煤炭(tan)價格計算，預(yu)計單(dan)個工作(zuo)(zuo)面(mian)可(ke)增(zeng)加直接(jie)收益406.3萬元。通過(guo)采(cai)掘(jue)(jue)設計調優(you)與沿空留巷(xiang)新(xin)技(ji)術(shu)應用等一系列舉措，保(bao)障了礦井安全穩定發展(zhan)。
針對(dui)綜(zong)采工(gong)(gong)(gong)(gong)(gong)(gong)(gong)區職工(gong)(gong)(gong)(gong)(gong)(gong)(gong)混合編制(zhi)且對(dui)綜(zong)采工(gong)(gong)(gong)(gong)(gong)(gong)(gong)藝生(sheng)疏的(de)(de)(de)實(shi)際，該(gai)(gai)礦重新進(jin)行(xing)組合優化(hua)，充分利用(yong)(yong)“師帶徒”“點帶面”“技術比(bi)武”“生(sheng)產會(hui)戰”等(deng)正面激(ji)勵手段(duan)，將區長當隊長用(yong)(yong)，隊長當班(ban)長用(yong)(yong)，不(bu)斷提(ti)高(gao)作(zuo)(zuo)業人(ren)員的(de)(de)(de)操作(zuo)(zuo)技能(neng)和技術力(li)量，達(da)到了減(jian)人(ren)員、減(jian)班(ban)次、不(bu)減(jian)產量的(de)(de)(de)新格(ge)局。實(shi)現集約化(hua)生(sheng)產后，他們抽調15人(ren)組建專業化(hua)隊伍，負責(ze)礦井工(gong)(gong)(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)面的(de)(de)(de)安(an)裝回(hui)撤(che)和安(an)全生(sheng)產標準(zhun)化(hua)的(de)(de)(de)整改工(gong)(gong)(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)，廢除了工(gong)(gong)(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)面安(an)撤(che)由外(wai)委隊伍施工(gong)(gong)(gong)(gong)(gong)(gong)(gong)的(de)(de)(de)狀況，還創造了16天圓滿(man)完(wan)成(cheng)安(an)撤(che)任務，比(bi)預期提(ti)前4天和日(ri)回(hui)撤(che)20架、安(an)裝19架的(de)(de)(de)紀錄(lu)。截至目(mu)前，該(gai)(gai)專業化(hua)隊伍已安(an)全高(gao)質量完(wan)成(cheng)礦井工(gong)(gong)(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)面安(an)裝5個(ge)、回(hui)撤(che)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)面3個(ge)的(de)(de)(de)任務，較原外(wai)委安(an)撤(che)施工(gong)(gong)(gong)(gong)(gong)(gong)(gong)隊伍8個(ge)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)面，可(ke)創效(xiao)近(jin)400萬(wan)元(yuan)。2021年(nian)5煤(mei)人(ren)均(jun)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)效(xiao)42.06噸/工(gong)(gong)(gong)(gong)(gong)(gong)(gong)，同比(bi)2020年(nian)29.8噸/工(gong)(gong)(gong)(gong)(gong)(gong)(gong)，提(ti)高(gao)了41%，人(ren)員減(jian)少了19人(ren)左右。
通過“三減三提(ti)”,各項(xiang)目實(shi)施和安(an)全(quan)(quan)生(sheng)產工作(zuo)寫實(shi)制度，大力(li)推動“機(ji)械化(hua)換人、自動化(hua)減人、提(ti)效減人”戰(zhan)略，預計全(quan)(quan)年減員37人，實(shi)現全(quan)(quan)礦井400人目標。
