Faced with the disaster of coal slag spilling down and burying many residential groups in Mong Duong ward (Cam Pha city), paralyzing the power system, Quang Ninh has mobilized many forces and made efforts to overcome the situation.
 |
| After the recent historic flood, Dam 790 became a vulnerable point, with the highest risk of insecurity in Cam Pha City. The large amount of water flowing from upstream caused landslides, surface displacement and risk of collapse. |
 |
| Part of the dam was blown wide open by the rain and floods. Authorities said that if the 790 dam broke, it would drag along rocks and level residential areas and paralyze the entire operation of the 110KV and 35KV power stations in Mong Duong ward, threatening the Mong Duong coal mine. |
 |
| The coal slag dump of Cao Son Coal Joint Stock Company and Coc 6 Coal Joint Stock Company is located inside dam 790. On the night of July 26, the dam broke, causing a large amount of coal slag sludge from a height of about 100 m to spill down below. |
 |
| Located right at the foot of the dam, Mong Duong Coal Company and Company 790 suffered heavy damage. Rainwater carried mud and flooded down, wiping out a mine entrance of Company 790. |
 |
| The slag overflowed to the foot of the dam, causing the mud and water to spread, raising the ground level by 3-4 meters in many places. |
 |
| A house in Group 1, Zone 4, Mong Duong Ward, located at the foot of the dam, was completely covered with coal slag on the first floor. Luckily, when the dam broke, the people were able to escape in time, so there were no casualties. |
 |
| Ms. Nguyen Thi Hang's house in group 1 was buried on the first floor. Seven months pregnant, when the coal slag mud flooded in, Ms. Hang was so scared that she could not walk. Her husband and 3 neighbors had to carry her and run. Currently, her family, as well as nearly 100 other households in groups 1 and 2, zone 4, have to take shelter at the ward health station and relatives' houses. |
 |
| To prevent the risk of the 790 dam collapsing, Mr. Dang Huy Hau, Vice Chairman of Quang Ninh Province, said that the province has coordinated with the Coal and Minerals Group to find ways to save the dam. The method is to adjust the flow to avoid the pressure of water and mud collapsing the lower dam body, and at the same time use excavators to dump soil, reinforce and raise the dam surface. |
 |
| Hundreds of soldiers and police were mobilized to shovel sand into sacks to build a dike to prevent mud from overflowing into the power booth area and residential area in Mong Duong ward. |
 |
| These artificial dikes will help prevent mud from entering the house. |
 |
| At the Mong Duong Ward Medical Station, hundreds of people are staying, with food, electricity and water provided. Mr. Pham Ngoc Lu, Vice Chairman of Mong Duong Ward People's Committee, said that due to continued rain, in order to avoid the risk of the coal slag dump continuing to burst, all households in Groups 3 and 4, Zone 4 will continue to be evacuated. |
