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。
靳圪(ge)塔梁(liang)隧(sui)道開(kai)工(gong)(gong)(gong)以來(lai)，中(zhong)鐵(tie)六局克服地質圍巖(yan)多變、施(shi)工(gong)(gong)(gong)干擾多、道路運輸等(deng)困(kun)難(nan)，根據(ju)現場(chang)情況及(ji)時調整施(shi)工(gong)(gong)(gong)隊(dui)伍，優化(hua)施(shi)工(gong)(gong)(gong)方案，認真分析各施(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)序的特(te)點(dian)和工(gong)(gong)(gong)序間的銜接，優化(hua)各工(gong)(gong)(gong)作(zuo)(zuo)面的作(zuo)(zuo)業(ye)(ye)方案，減少非作(zuo)(zuo)業(ye)(ye)時間，將機械和人員得到有(you)效配置，縮短(duan)了時間。按照(zhao)隧(sui)道施(shi)工(gong)(gong)(gong)“短(duan)開(kai)挖、強(qiang)支護、早封閉、勤測量(liang)”的原(yuan)則，加強(qiang)對現場(chang)施(shi)工(gong)(gong)(gong)的監控，做到提前(qian)發(fa)現安全隱患，及(ji)時處(chu)理，確(que)保了工(gong)(gong)(gong)程的順(shun)利進展和安全質量(liang)。
