Dong Hy – VietNamNet Bridge –
The massive mineral exploitation at four sites in Dong Hy district in Thai Nguyen province has led to serious consequences: the houses of 133 families have been affected by subsidence and cracking, and locals do not have water for daily life.

A pit belonging to Thai Nguyen Black Metallurgical JSC is located in a residential quarter.
Duong Van Tuyen in Hoa Binh hamlet in Cay Thi commune, whose house is located next to a pit, said many years ago, there was no serious problem because the exploitation was carried out at shallows.
