online project has long tunnel of 8.6 km, two vertical wells each 170m deep wells, a pressurized tower 150m deep and three sub-basement to serve construction of the tunnel length is 300 meters on average each tunnel.

energy lies primarily in major regional geology, rocks are strongly weathered; much space is land and mud. Song Da 7.10 Enterprise under the Song Da Corporation, a unit 10 to execute this project.

Mirror No. 9 after the end of March 2010, construction units conducted by drilling vertical wells and Robin, while bottom-up was conducted 60m is met near the weak soil caused landslides filled the entire section on more than 40 m length horizontal tunnels, interrupting the execution of this well.
Mirror No. 8 after going through the area near the 900m, the bottom of an ancient underground springs 100m, the construction company had used the special construction methods to construction near the 900m tunnel, but to meet this large amount of underground water, the roof of a mud pit subsidence has caused thousands of cubic meters of mud covered the entire 100md basement flooding, the construction was not possible landslides due to soil, create a hole tens of meters above the ground, although more than 100 meters deep underground.
