Dong Nai has a surplus of nearly 13 million cbm of fill material and embankment soil at rock quarries

According to Tran Trong Toan, Deputy Director of the Department of Agriculture and Environment of Dong Nai province, there is currently an enormous surplus of fill material (leveling materials) generated during mineral exploitation at construction stone quarries in the province.

After working with quarry owners, the Department of Agriculture and Environment recorded nearly 13 million cubic meters (cbm) of leveling materials, mainly leveling soil and weathered rock recovered during the stripping of overburden for stone exploitation.

Some quarries with large material volumes include Tan Cang 9, with approximately 3.5 million cubic meters; Tan Cang 6, with about 3.4 million cubic meters; Tan Cang 7, with around 2.5 million cubic meters; Thien Tan 9, with approximately 2 million cubic meters; and Tan Cang 1, with about 1.5 million cubic meters.

In addition, quarries such as Thien Tan 5, Thien Tan 7, Thien Tan 4, Tan Cang 2, Thien Tan 3, Ap Mieu, Nui Nua, Tan Cang 3, and Thanh Phu 2 have leveling material volumes ranging from 50,000 to 250,000 cubic meters.

Currently, many mineral quarries have a large surplus of fill dirt and weathered rock, which affects the site conditions for stone exploitation, serving key projects in the South. In the photo: Stone exploitation in Phuoc Tan Ward. Photo: Hoang Loc

According to the Department of Agriculture and Environment, to exploit construction stone to serve key projects in the South that are in high demand, it is first necessary to clear the volume of leveling materials currently stockpiled at the quarries. However, project management boards and contractors have not yet contacted exploitation enterprises to recover and utilize this material source, affecting the progress of stone exploitation construction.

The Department of Agriculture and Environment, along with enterprises, unanimously proposed that the Provincial People's Committee notify project management boards and contractors so they can proactively coordinate and work together to receive and utilize the recovered leveling materials, while also creating a site for stone exploitation.

If, after November 15, the project management boards do not provide written feedback on the demand for leveling materials, the Department of Agriculture and Environment will compile the information and report to the Provincial People's Committee for review and direction on subsequent handling measures.
