山能訊 近日(ri)，地處延安(an)的臨礦(kuang)集(ji)團永明礦(kuang)通(tong)過現場環環寫實(shi)，找準制(zhi)約高效采煤的難點和癥結(jie)，打破原有(you)思(si)維定式，在5煤工(gong)(gong)(gong)作(zuo)面率(lv)先實(shi)現單(dan)班單(dan)面生產(chan)，人(ren)(ren)均工(gong)(gong)(gong)效42.06噸(dun)/工(gong)(gong)(gong)，同比提高41%，人(ren)(ren)員(yuan)減少19人(ren)(ren)左右，創效過千(qian)萬元，實(shi)現了集(ji)約化安(an)全高效生產(chan)。
他(ta)們大(da)力推行“三減三提”和設(she)備升級(ji)，自主(zhu)創(chuang)新改造單軌吊式電(dian)纜滑車、皮帶自移機尾(wei)、邁步自移式超前支架、支架增設(she)抬底(di)缸，升級(ji)安裝了純凈水處理與恒(heng)壓供水系統，完成了采煤機更換搖臂、液(ye)壓支架更換液(ye)壓元件等一系列設(she)備升級(ji)改造項(xiang)目(mu)。皮帶負荷率由(you)54.56%提高66.54%，設(she)備開機率由(you)70.1提高80%。
采(cai)掘(jue)先行，設(she)計(ji)(ji)為(wei)本。他(ta)們(men)對采(cai)掘(jue)工(gong)作(zuo)面(mian)設(she)計(ji)(ji)進(jin)(jin)行優(you)化，積極探索沿(yan)空(kong)留巷(xiang)新模式，采(cai)用產(chan)氣具非爆破預(yu)裂切頂沿(yan)空(kong)留巷(xiang)技術(shu)，由(you)年(nian)初4個(ge)掘(jue)進(jin)(jin)頭降為(wei)2個(ge)掘(jue)進(jin)(jin)頭，每個(ge)工(gong)作(zuo)面(mian)可減少掘(jue)進(jin)(jin)進(jin)(jin)尺(chi)約900米，減少施(shi)工(gong)時(shi)(shi)間(jian)2.2個(ge)月(yue)(yue)，增加單個(ge)工(gong)作(zuo)面(mian)儲量4.83萬(wan)噸(dun)，多(duo)回(hui)收(shou)煤(mei)炭0.31萬(wan)噸(dun)。同時(shi)(shi)，延長工(gong)作(zuo)面(mian)服(fu)務時(shi)(shi)間(jian)2.1月(yue)(yue)，每年(nian)減少工(gong)作(zuo)面(mian)搬家1次(ci)，萬(wan)噸(dun)掘(jue)進(jin)(jin)率由(you)164.4m/wt降低(di)為(wei)82.9m/wt。按照當前煤(mei)炭價格計(ji)(ji)算，預(yu)計(ji)(ji)單個(ge)工(gong)作(zuo)面(mian)可增加直(zhi)接收(shou)益406.3萬(wan)元。通過(guo)采(cai)掘(jue)設(she)計(ji)(ji)調(diao)優(you)與沿(yan)空(kong)留巷(xiang)新技術(shu)應用等一(yi)系列舉措，保障了礦井安全穩定(ding)發展。
