Search efforts continued for a sixth day Wednesday to find a worker missing in the collapse of a subway construction site in the city of Gwangmyeong.
The construction site for the Sinansan Line collapsed Friday, causing a section of the road above ground to cave in and damaging several buildings.
Rescue workers have been working almost around the clock to find the 50-something worker who is the only person still missing in the accident.
As of Wednesday morning, workers had dug 21 meters into the ground, with the total depth of the construction site being 34.5 meters, according to the Gyeonggi Fire Service.
They also removed some 300 tons of soil and sand overnight after creating a passage to the bottom of the underground tunnel and driving in a small excavator.
Firefighters said they searched the interior several times with the help of four rescue dogs, but failed to find any signs of the missing.
The fire service plans to mobilize 73 personnel, 26 pieces of equipment and four rescue dogs for rescue operations Wednesday.
Other agencies, including the police, the Gwangmyeong municipal government and the labor and land ministries, also plan to assist with 199 personnel and 42 pieces of equipment.
The missing worker is presumed to be located 35 to 40 meters underground, but his exact location and condition remain unknown. (Yonhap)
