The city plans to set off mines in these tunnels in early June, using 300-500kg of explosive.
Before setting explosion, the authorities will use loudspeakers to call for tin exploiters to get out of the tunnels.
On May 25, sappers made a survey in this network of tunnels and found out a total of four doors to get into the tangled tunnels. There was a lot of food, drink and equipment inside the tunnel.
The local authorities blockaded this area 24/7 since May 17 but the drink, food and equipment left in the tunnels showed that illegal tin miners kept operating there.
A tin miner said that all tunnels head to the tin ground which was leveled five years ago because this site is said to have large tin reserve.
