On 23rd Oct， as concrete pouring was completed in ore fines chamber at shaft bottom, the sinking, lining and installation works at 2# prospecting shaft in Daxinganling Project was successfully completed.
Daxinganling Project locates at the north side of Yilehuli Mountain with continental cold temperature climate. 2# prospecting shaft is 1254.17m in depth and 6m net diameter with 500mm lining, plus twenty ingates, two skip loading chambers, two pipe chutes. The climate there is very challenging with annual average temperature about -5℃ and lowest at -40℃ thus presents much difficulties for the work. Since commencement in 2012, despite of the harsh environment and poor geological conditions, the leaders and crew strengthened management and communications, optimized work plan and made detailed arrangement during construction, finally ensuring the successful completion of the project on 23rd Oct and was accepted on 26th.
