永明煤礦根(gen)據集團公司(si)“提(ti)速減面、連續生(sheng)(sheng)產、單班生(sheng)(sheng)產”工(gong)作要(yao)求(qiu),通過(guo)現(xian)場環環寫實,不斷優(you)化勞動(dong)組織(zhi)、優(you)化洗配比例(li)等手段,研究出一條“打破瓶頸(jing)、提(ti)高管(guan)理(li)、提(ti)升素質、集約高效(xiao)(xiao)”的自我發(fa)展之路(lu),實現(xian)了集約化安全高效(xiao)(xiao)生(sheng)(sheng)產。
一、全系統調優為集約化生產奠定基礎
1.向裝備升級要效率。大力推行“三減三提(ti)”和設備(bei)升(sheng)級,自主(zhu)創(chuang)新改造(zao)單(dan)軌(gui)吊式電纜(lan)滑(hua)車、皮帶自移(yi)機尾、邁步自移(yi)式超前(qian)支架(jia)、支架(jia)增設抬底(di)缸,升(sheng)級安(an)裝了純凈水(shui)處理(li)與恒壓供水(shui)系統,更換采煤機搖臂、液壓支架(jia)元件(jian)等一系列設備(bei)升(sheng)級改造(zao)項目,皮帶負荷率(lv)由54.56%提(ti)高到(dao)66.54%,設備(bei)開機率(lv)由70.1%提(ti)高到(dao)80%。
2.向業務素質提升要效益。針對(dui)綜采(cai)工(gong)(gong)區(qu)職工(gong)(gong)混合編制且(qie)對(dui)綜采(cai)工(gong)(gong)藝(yi)生疏的實(shi)(shi)際,重新(xin)進(jin)行組合優化,充分利(li)用(yong)“師帶徒(tu)”“點帶面”“技術(shu)比(bi)武”“生產會(hui)戰”等(deng)正面激勵(li)手(shou)段,將區(qu)長(chang)(chang)(chang)當隊長(chang)(chang)(chang)用(yong),隊長(chang)(chang)(chang)當班長(chang)(chang)(chang)用(yong),現場實(shi)(shi)踐(jian)與理論相結(jie)合,不斷提(ti)高作(zuo)業人員(yuan)的操(cao)作(zuo)技能和技術(shu)力量(liang),達到了(le)“減人員(yuan)、減班次、不減產量(liang)”的新(xin)格局。
3.向集中化檢修要保障。設備的(de)(de)正常(chang)運行是實(shi)現(xian)(xian)高效采(cai)(cai)煤的(de)(de)重要(yao)保障,實(shi)現(xian)(xian)集(ji)約(yue)化生產(chan)后,及時(shi)對檢(jian)修(xiu)時(shi)間做出(chu)調整(zheng),將(jiang)夜班作為集(ji)中(zhong)檢(jian)修(xiu)班。同時(shi)加強對機電(dian)修(xiu)人(ren)員的(de)(de)培養力度,采(cai)(cai)用提高工資待遇和“師帶(dai)徒”等激勵(li)政策(ce),通過請廠家(jia)人(ren)員到礦現(xian)(xian)場指(zhi)導、外(wai)出(chu)培訓(xun)學習(xi)、制定詳(xiang)細(xi)的(de)(de)培訓(xun)學習(xi)計劃等,切實(shi)提高機電(dian)修(xiu)人(ren)員的(de)(de)操作技能、檢(jian)修(xiu)質量和故障判斷能力。
4.采掘設計調優穩接續。對采掘工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)(mian)(mian)(mian)設(she)計進(jin)(jin)行優(you)化,積極探索沿(yan)空留(liu)巷(xiang)新(xin)模式(shi)(shi),采用產氣(qi)具非爆破預裂切頂(ding)沿(yan)空留(liu)巷(xiang)技術,留(liu)巷(xiang)效(xiao)果(guo)顯著,真正從技術上達到(dao)降本提效(xiao)、緩解(jie)接續緊張問(wen)題;通過工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)(mian)(mian)(mian)成功留(liu)巷(xiang),3號煤(mei)可全部實現“一面(mian)(mian)(mian)(mian)(mian)一巷(xiang)”模式(shi)(shi),每(mei)個工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)(mian)(mian)(mian)可減少(shao)(shao)掘進(jin)(jin)進(jin)(jin)尺約900米(mi)(mi),減少(shao)(shao)施工(gong)(gong)(gong)時間2.2個月(yue),增(zeng)加(jia)(jia)單個工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)(mian)(mian)(mian)儲量4.83萬(wan)(wan)噸,多回收(shou)煤(mei)炭(tan)0.31萬(wan)(wan)噸,延長工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)(mian)(mian)(mian)服務時間2.1月(yue),每(mei)年減少(shao)(shao)工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)(mian)(mian)(mian)搬家1次、萬(wan)(wan)噸掘進(jin)(jin)率(lv)由164.4米(mi)(mi)/萬(wan)(wan)噸降低為82.9米(mi)(mi)/萬(wan)(wan)噸。按照當前煤(mei)炭(tan)價(jia)格計算(suan),預計單個工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)(mian)(mian)(mian)可增(zeng)加(jia)(jia)收(shou)益406.3萬(wan)(wan)元(yuan)。采用放(fang)大面(mian)(mian)(mian)(mian)(mian)、放(fang)長面(mian)(mian)(mian)(mian)(mian)方式(shi)(shi),工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)(mian)(mian)(mian)長度由原來128米(mi)(mi)優(you)化為190米(mi)(mi),保證(zheng)了“三量”平衡和礦井安(an)全穩定發展(zhan)。
二、集約化生產推進礦井高產高效
1.專業化隊伍創高效。實現(xian)集約化生(sheng)產后,抽(chou)調(diao)15人(ren)組建專業化隊伍(wu),負責工(gong)作面安(an)裝(zhuang)回撤(che)和安(an)全生(sheng)產標準化整改工(gong)作,結束了工(gong)作面安(an)撤(che)由外委隊伍(wu)施工(gong)的現(xian)狀,還創造(zao)了16天(tian)圓滿完成(cheng)安(an)撤(che)任(ren)務、比預期提(ti)前4天(tian)和日回撤(che)20架、安(an)裝(zhuang)19架的紀(ji)錄。截止目前,該專業化隊伍(wu)已安(an)全高(gao)質完成(cheng)礦(kuang)井工(gong)作面安(an)裝(zhuang)5個、回撤(che)工(gong)作面3個,創效近400萬元(yuan)。
2.綜采班組創高效。由于3號(hao)、5號(hao)原煤(mei)(mei)(mei)(mei)不同的煤(mei)(mei)(mei)(mei)質(zhi)特性,只有配(pei)比(bi)趨于穩定(ding),才(cai)能(neng)保證經(jing)濟(ji)效(xiao)益(yi)最大化和穩定(ding)的產(chan)品指標(biao)。通(tong)過在洗煤(mei)(mei)(mei)(mei)廠不斷試驗和寫實,得出了(le)3號(hao)煤(mei)(mei)(mei)(mei)與5號(hao)煤(mei)(mei)(mei)(mei)在1:1——1:1.2配(pei)比(bi)下才(cai)能(neng)實現(xian)效(xiao)益(yi)最大化的經(jing)驗。由此溯源(yuan)到采(cai)場,優化綜采(cai)生產(chan)布局,將原有5號(hao)煤(mei)(mei)(mei)(mei)2個班(ban)(ban)生產(chan)、3號(hao)煤(mei)(mei)(mei)(mei)3個班(ban)(ban)生產(chan)逐步(bu)向5號(hao)煤(mei)(mei)(mei)(mei)單班(ban)(ban)生產(chan)、3號(hao)煤(mei)(mei)(mei)(mei)兩班(ban)(ban)生產(chan)模式邁進,實現(xian)集約化安全高(gao)效(xiao)生產(chan)。
集約化生產前后對比
自2020年5月份(fen)實現(xian)集(ji)約(yue)化生產以來,5煤人均工(gong)效42.06噸/工(gong)同比提高41%,減少用工(gong)19人。
3.向集約化洗煤要效益。自井下(xia)實(shi)現集(ji)約化生產后,洗(xi)煤(mei)廠(chang)也(ye)隨之改變洗(xi)煤(mei)和(he)檢修(xiu)時間(jian),在智能監控、在線監測、三質體復合(he)高頻電磁(ci)脫泥篩、轉彎(wan)皮帶“三合(he)一(yi)”等(deng)一(yi)系列升級改造項目的前提下(xia),將原來兩班洗(xi)煤(mei)改成夜班集(ji)中(zhong)洗(xi)煤(mei),實(shi)現了集(ji)中(zhong)檢修(xiu)和(he)集(ji)中(zhong)洗(xi)煤(mei)“雙豐收(shou)”。
