山(shan)能訊 近日，地處延安的(de)臨礦集(ji)(ji)團永明礦通過(guo)現場環環寫實，找準制約高效采煤的(de)難點和癥(zheng)結，打破原有思維定式，在5煤工作(zuo)面(mian)率先實現單班單面(mian)生(sheng)產，人均工效42.06噸/工，同比提高41%，人員減(jian)少(shao)19人左右，創效過(guo)千(qian)萬(wan)元(yuan)，實現了集(ji)(ji)約化安全高效生(sheng)產。
他們大力推行“三減三提”和設(she)(she)備(bei)升(sheng)級(ji)，自(zi)(zi)主(zhu)創(chuang)新改造(zao)單軌吊式電纜滑車、皮帶自(zi)(zi)移機(ji)尾、邁步自(zi)(zi)移式超前支架、支架增設(she)(she)抬(tai)底缸(gang)，升(sheng)級(ji)安裝了純凈水處理(li)與恒壓供(gong)水系統，完(wan)成了采煤機(ji)更換搖臂、液(ye)壓支架更換液(ye)壓元件等一系列設(she)(she)備(bei)升(sheng)級(ji)改造(zao)項目(mu)。皮帶負荷率(lv)(lv)由54.56%提高66.54%，設(she)(she)備(bei)開機(ji)率(lv)(lv)由70.1提高80%。
采(cai)掘(jue)先行，設計(ji)(ji)為(wei)(wei)本。他(ta)們對(dui)采(cai)掘(jue)工(gong)(gong)作面(mian)設計(ji)(ji)進(jin)(jin)(jin)(jin)行優化(hua)，積極探索(suo)沿空留(liu)(liu)巷新模式(shi)，采(cai)用產(chan)氣具(ju)非爆(bao)破預裂切頂沿空留(liu)(liu)巷技(ji)術，由年初4個掘(jue)進(jin)(jin)(jin)(jin)頭降(jiang)為(wei)(wei)2個掘(jue)進(jin)(jin)(jin)(jin)頭，每個工(gong)(gong)作面(mian)可減少掘(jue)進(jin)(jin)(jin)(jin)進(jin)(jin)(jin)(jin)尺約900米，減少施工(gong)(gong)時間(jian)2.2個月(yue)，增加(jia)(jia)單個工(gong)(gong)作面(mian)儲(chu)量4.83萬(wan)噸(dun)(dun)(dun)，多回收煤炭0.31萬(wan)噸(dun)(dun)(dun)。同(tong)時，延長(chang)工(gong)(gong)作面(mian)服務時間(jian)2.1月(yue)，每年減少工(gong)(gong)作面(mian)搬家1次，萬(wan)噸(dun)(dun)(dun)掘(jue)進(jin)(jin)(jin)(jin)率由164.4m/wt降(jiang)低(di)為(wei)(wei)82.9m/wt。按照當前煤炭價(jia)格計(ji)(ji)算(suan)，預計(ji)(ji)單個工(gong)(gong)作面(mian)可增加(jia)(jia)直接收益406.3萬(wan)元。通過采(cai)掘(jue)設計(ji)(ji)調優與沿空留(liu)(liu)巷新技(ji)術應(ying)用等(deng)一系列(lie)舉措，保障了(le)礦(kuang)井安全穩定發展。
