化繁(fan)為(wei)簡,打造輔助運(yun)輸(shu)“快(kuai)車道”。該礦創新采(cai)用(yong)“地面(mian)直達井(jing)(jing)下砂(sha)石(shi)料(liao)輸(shu)送系統(tong)”+“長距離回采(cai)巷道精(jing)干輔助運(yun)輸(shu)”模式,實(shi)現砂(sha)石(shi)料(liao)自(zi)地面(mian)攪拌站經(jing)輸(shu)料(liao)孔到(dao)井(jing)(jing)下儲(chu)料(liao)倉,自(zi)儲(chu)料(liao)倉經(jing)轉(zhuan)運(yun)系統(tong)到(dao)底(di)(di)卸(xie)式集裝箱,再由單(dan)軌吊轉(zhuan)運(yun)至(zhi)順(shun)槽快(kuai)速(su)裝卸(xie)站,最后經(jing)底(di)(di)皮帶傳送至(zhi)使(shi)用(yong)地點(dian)的全(quan)過程,極大縮短砂(sha)石(shi)料(liao)運(yun)輸(shu)時(shi)間,同時(shi)有效緩解副井(jing)(jing)提升(sheng)壓(ya)力,每(mei)年可減少電費及(ji)人(ren)工成(cheng)本20余萬(wan)元。
工(gong)欲善其(qi)事,必(bi)先利(li)其(qi)器。上(shang)海廟(miao)礦區屬典型(xing)的(de)侏羅紀富水(shui)軟巖地(di)層,巷(xiang)道極易發(fa)生較為嚴重的(de)底鼓變形,工(gong)藝復雜、支護強度大。為打破(po)制約快(kuai)速掘(jue)(jue)進(jin)(jin)(jin)(jin)效率(lv)的(de)瓶頸,該(gai)礦不斷(duan)探索采(cai)用(yong)(yong)(yong)EBZ200C型(xing)掘(jue)(jue)進(jin)(jin)(jin)(jin)機(ji)(ji)(ji)(ji),配合自(zi)移式(shi)(shi)皮(pi)(pi)(pi)帶(dai)機(ji)(ji)(ji)(ji)尾(wei)、封閉式(shi)(shi)機(ji)(ji)(ji)(ji)尾(wei)、自(zi)移式(shi)(shi)串車(che)等成熟改造項目(mu),并對噴(pen)漿(jiang)機(ji)(ji)(ji)(ji)、皮(pi)(pi)(pi)帶(dai)機(ji)(ji)(ji)(ji)、自(zi)動推料機(ji)(ji)(ji)(ji)等進(jin)(jin)(jin)(jin)行升(sheng)級改造,噴(pen)漿(jiang)機(ji)(ji)(ji)(ji)由10立方升(sheng)級為13立方,噴(pen)漿(jiang)效率(lv)提高33%。順槽掘(jue)(jue)進(jin)(jin)(jin)(jin)期間安裝回采(cai)使用(yong)(yong)(yong)的(de)2×315千(qian)瓦永(yong)磁(ci)皮(pi)(pi)(pi)帶(dai)機(ji)(ji)(ji)(ji),掘(jue)(jue)進(jin)(jin)(jin)(jin)完(wan)成后直接用(yong)(yong)(yong)于(yu)采(cai)煤(mei)工(gong)作面生產,首次(ci)實現“掘(jue)(jue)進(jin)(jin)(jin)(jin)—回采(cai)”一條皮(pi)(pi)(pi)帶(dai)用(yong)(yong)(yong)到底。采(cai)用(yong)(yong)(yong)“自(zi)動推料機(ji)(ji)(ji)(ji)+底皮(pi)(pi)(pi)帶(dai)運(yun)料”的(de)方式(shi)(shi)解決了砂石料長距離運(yun)輸難題(ti),該(gai)裝置(zhi)每(mei)年將減少人工(gong)成本130余萬元(yuan)。同時,該(gai)礦注重激(ji)發(fa)員工(gong)的(de)積極性(xing)和(he)創(chuang)造性(xing),對實用(yong)(yong)(yong)型(xing)創(chuang)新項目(mu)進(jin)(jin)(jin)(jin)行即(ji)時獎(jiang)勵,1-7月共獎(jiang)勵448人次(ci),累計獎(jiang)勵11.5萬元(yuan)。
該礦(kuang)還不斷(duan)加(jia)強(qiang)安全生(sheng)產標準化(hua)建設(she),樹(shu)立(li)“一(yi)次做(zuo)對、一(yi)次做(zuo)好”理(li)念,制定印發《榆(yu)樹(shu)井(jing)煤礦(kuang)現場寫(xie)(xie)實(shi)制度》,“以現場問(wen)題(ti)(ti)為導向”對采掘工(gong)作面(mian)(mian)及生(sheng)產系(xi)統進行全面(mian)(mian)寫(xie)(xie)實(shi)。根(gen)據“寫(xie)(xie)實(shi)—改進—再(zai)寫(xie)(xie)實(shi)—再(zai)改進”的原則,形成“主動寫(xie)(xie)實(shi)發現問(wen)題(ti)(ti)”和(he)“帶著(zhu)問(wen)題(ti)(ti)探尋(xun)方案”兩(liang)種寫(xie)(xie)實(shi)方式(shi),發現制約生(sheng)產的瓶頸問(wen)題(ti)(ti),引導管理(li)向重點問(wen)題(ti)(ti)、關(guan)鍵環節突破。通過寫(xie)(xie)實(shi)工(gong)作,有(you)效解決勞(lao)動組織、裝備改進、運(yun)輸優化(hua)等方面(mian)(mian)的17項(xiang)難題(ti)(ti)。(劉紅亮)
