12月21日，中鐵六局承建的大包電氣化改造工程靳圪塔梁隧道順利貫通。
靳圪塔梁隧道位于山西省大同市興榮區堡子灣鄉境內，全長1460m，隧道最大埋深66m，是大包電氣化改造工程新建六座隧道中最長的一座，也是全線唯一當年開工當年貫通的隧道。
靳(jin)圪塔梁(liang)隧道(dao)開工(gong)(gong)(gong)(gong)以來，中鐵六局克服地質(zhi)圍巖多變、施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)干擾多、道(dao)路(lu)運輸等(deng)困難，根據現(xian)場(chang)情況及時(shi)調(diao)整施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)隊伍，優化施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)方案(an)，認(ren)真分析各施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)序(xu)的特(te)點和(he)工(gong)(gong)(gong)(gong)序(xu)間(jian)的銜(xian)接，優化各工(gong)(gong)(gong)(gong)作面的作業方案(an)，減少非(fei)作業時(shi)間(jian)，將機械(xie)和(he)人員得到有效配置，縮短了(le)時(shi)間(jian)。按照隧道(dao)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)“短開挖、強支護、早封閉、勤測量(liang)”的原則，加(jia)強對現(xian)場(chang)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)的監控，做到提前發現(xian)安(an)全(quan)隱患，及時(shi)處理，確保了(le)工(gong)(gong)(gong)(gong)程的順(shun)利進展和(he)安(an)全(quan)質(zhi)量(liang)。
