本網濟寧(ning)訊 “自從用(yong)上組合可調式(shi)擋煤(mei)(mei)板，皮帶尾(wei)堵塞問(wen)題徹(che)底解(jie)決了，我再也不用(yong)每天清理積煤(mei)(mei)，工(gong)作(zuo)比以前(qian)(qian)輕松多(duo)了。”日前(qian)(qian)，新驛(yi)煤(mei)(mei)礦運搬(ban)工(gong)區皮帶巡檢工(gong)張達偉(wei)正在開心地介紹皮帶精益管理帶來(lai)的變化。
這一(yi)變化得益于該(gai)礦(kuang)實施的“輸送(song)機精致線條管理(li)法(fa)(fa)”。以往(wang)該(gai)礦(kuang)井下(xia)皮帶(dai)轉(zhuan)載(zai)點處(chu)經常發生積(ji)堵現象，需要專人進(jin)行清理(li)，既費時費力，又有安(an)全(quan)(quan)隱患。為此，該(gai)礦(kuang)運(yun)用精益理(li)念和工具方(fang)法(fa)(fa)，以消除浪費和不斷(duan)改善為核心，對井下(xia)全(quan)(quan)部皮帶(dai)轉(zhuan)載(zai)點擋煤板進(jin)行升級改造，同時配合(he)(he)使用皮帶(dai)護網，形成組(zu)合(he)(he)可調式擋煤板，實現皮帶(dai)運(yun)輸封閉轉(zhuan)載(zai)，保證了皮帶(dai)在運(yun)輸過(guo)程中(zhong)不漏一(yi)粒煤，不掉一(yi)塊矸，徹底解決皮帶(dai)尾(wei)積(ji)煤問題，同時降低了工人勞動強度，減(jian)少崗(gang)位工1人。
今年(nian)以(yi)來，該礦(kuang)扎實推進“兩(liang)化融(rong)合”管(guan)(guan)(guan)理(li)(li)工作(zuo)，他們以(yi)精益(yi)管(guan)(guan)(guan)理(li)(li)強化過(guo)程管(guan)(guan)(guan)控，通過(guo)實施“線條精致管(guan)(guan)(guan)理(li)(li)法(fa)”和現場(chang)全過(guo)程寫實，將礦(kuang)井(jing)安全管(guan)(guan)(guan)理(li)(li)、高效(xiao)采煤、快速掘(jue)進、勞動組織、煤質管(guan)(guan)(guan)理(li)(li)、成(cheng)本管(guan)(guan)(guan)控等各(ge)專業，按照“從(cong)(cong)源頭到終端、從(cong)(cong)采購到現場(chang)應用、從(cong)(cong)生產到銷售、從(cong)(cong)隱(yin)患排查(cha)到現場(chang)整改(gai)”的“線條精致管(guan)(guan)(guan)理(li)(li)法(fa)”，進行(xing)直(zhi)線串聯，查(cha)找分析管(guan)(guan)(guan)理(li)(li)短板，完(wan)善優(you)化作(zuo)業流程，全面挖掘(jue)降本增效(xiao)空間。
“我們及時(shi)(shi)查(cha)改管(guan)理粗放(fang)、低效運行問題(ti)(ti)，通過工(gong)作面(mian)生(sheng)產全過程寫(xie)實解決人員配置不(bu)合理、電纜、皮帶老化(hua)、勞動組織不(bu)合理等制約工(gong)作面(mian)推采的問題(ti)(ti)。現在一個工(gong)作面(mian)單(dan)循環時(shi)(shi)間由180分鐘縮短至150分鐘，生(sheng)產效率提高了17%。”該(gai)礦生(sheng)產副(fu)礦長李永(yong)強介(jie)紹。
該礦(kuang)以(yi)(yi)完全市場化(hua)管理(li)為載(zai)體，以(yi)(yi)精益(yi)管理(li)工(gong)(gong)(gong)(gong)(gong)具應用(yong)為手段，在(zai)高(gao)效運輸(shu)、快速掘進、節支降(jiang)耗、材料費(fei)用(yong)等方面實現整(zheng)體效益(yi)最大化(hua)。井下副井三環水倉(cang)掘進工(gong)(gong)(gong)(gong)(gong)作面、地面支架(jia)維修(xiu)推行市場化(hua)承包試點后，人工(gong)(gong)(gong)(gong)(gong)效率及工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)(cheng)質量(liang)得到大幅度(du)提高(gao)，生產任務(wu)由原來(lai)的月進尺50.3米(mi)(mi)提高(gao)到70.2米(mi)(mi)，工(gong)(gong)(gong)(gong)(gong)效由0.055米(mi)(mi)/工(gong)(gong)(gong)(gong)(gong)提高(gao)到0.06米(mi)(mi)/工(gong)(gong)(gong)(gong)(gong)，提高(gao)9.1%，工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)(cheng)質量(liang)由原來(lai)的每月1個(ge)優(you)(you)良工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)(cheng)提高(gao)到2兩(liang)個(ge)優(you)(you)良工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)(cheng)，工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)(cheng)質量(liang)獎(jiang)勵(li)計件(jian)工(gong)(gong)(gong)(gong)(gong)資5%以(yi)(yi)上。截至(zhi)目前，該礦(kuang)通(tong)過系統(tong)優(you)(you)化(hua)，標準化(hua)流程(cheng)(cheng)(cheng)再(zai)造，降(jiang)低用(yong)電負(fu)荷2100千(qian)瓦，降(jiang)低電耗355度(du)/天，節省費(fei)用(yong)223元/天，累(lei)計減少系統(tong)維護材料費(fei)用(yong)約110萬元，精益(yi)管理(li)成效顯著(zhu)。（劉娟）
