他(ta)們大(da)力推行“三減三提(ti)”和設(she)備(bei)升(sheng)級，自(zi)主(zhu)創新改造(zao)(zao)單軌吊式(shi)(shi)電(dian)纜滑車、皮(pi)(pi)帶(dai)自(zi)移機(ji)(ji)尾、邁步自(zi)移式(shi)(shi)超前支架、支架增設(she)抬底缸，升(sheng)級安裝(zhuang)了純凈水處理與恒壓供水系統，完(wan)成了采煤機(ji)(ji)更換搖臂、液(ye)(ye)壓支架更換液(ye)(ye)壓元件等一(yi)系列設(she)備(bei)升(sheng)級改造(zao)(zao)項目。皮(pi)(pi)帶(dai)負荷(he)率由(you)54.56%提(ti)高(gao)66.54%，設(she)備(bei)開機(ji)(ji)率由(you)70.1提(ti)高(gao)80%。
采(cai)掘(jue)(jue)先行，設(she)計為本(ben)。他們對(dui)采(cai)掘(jue)(jue)工(gong)(gong)(gong)作面(mian)設(she)計進(jin)行優化(hua)，積極(ji)探索沿(yan)空留巷新模式，采(cai)用產氣具非爆破預裂切頂(ding)沿(yan)空留巷技術，由(you)年(nian)初4個(ge)掘(jue)(jue)進(jin)頭降為2個(ge)掘(jue)(jue)進(jin)頭，每個(ge)工(gong)(gong)(gong)作面(mian)可減(jian)(jian)(jian)少掘(jue)(jue)進(jin)進(jin)尺約900米，減(jian)(jian)(jian)少施工(gong)(gong)(gong)時(shi)間2.2個(ge)月，增(zeng)加單個(ge)工(gong)(gong)(gong)作面(mian)儲(chu)量4.83萬(wan)噸(dun)，多(duo)回收煤炭(tan)0.31萬(wan)噸(dun)。同時(shi)，延長工(gong)(gong)(gong)作面(mian)服務(wu)時(shi)間2.1月，每年(nian)減(jian)(jian)(jian)少工(gong)(gong)(gong)作面(mian)搬家1次，萬(wan)噸(dun)掘(jue)(jue)進(jin)率由(you)164.4m/wt降低為82.9m/wt。按照當前煤炭(tan)價格計算，預計單個(ge)工(gong)(gong)(gong)作面(mian)可增(zeng)加直接(jie)收益(yi)406.3萬(wan)元。通過采(cai)掘(jue)(jue)設(she)計調優與沿(yan)空留巷新技術應用等一系列舉措，保障了礦井安全穩定發展。
