Providing landfill materials for key projects

In recent times, the province has regularly and continuously directed the settlement of procedures to put mines into exploitation; allowed the exploitation of excess soil and rock volumes at projects; accelerated the completion of procedures for exploiting sand mines for filling; strengthened solutions to exploit and effectively use mine waste soil and rock as filling materials... to ensure serving the needs of key projects in the area.

In the Planning of Quang Ninh province for the period 2021-2030, with a vision to 2050 approved by the Prime Minister in Decision No. 80/QD-TTg dated February 11, 2023, 79 hill mines that can be put into exploitation for use as landfill materials in the period up to 2030, with reserves of about 250 million ^m3 ; 31 areas for mining coal mine waste soil and rock with reserves of about 150 million ^m3 .

In addition, the province also has sand mines (about 49.3 million ^m3 ) that can serve as filling for projects; dredging projects of seaports and waterways generate nearly 33 million ^m3. Dredged materials; thermal power plants generate about 35 million ^m3 Thermal power plant ash and slag can be used as landfill material. These materials can be used as substitutes for traditional hill soil sources.

With the thorough and close direction of the province, there have been many changes in the supply of filling materials. In particular, regarding the licensing of soil and rock mines for filling materials, implementing the Provincial Planning, the Provincial People's Committee has demarcated 10 areas of soil and rock mines for filling materials without auctioning mineral exploitation rights and 7 areas of auctioning mineral exploitation rights with a total reserve of 112.5 million ^m3 . The Provincial People's Committee has granted 10 mineral exploitation licenses for soil and rock mines for filling materials; 6 mining areas are completing mineral exploitation license dossiers. In the first 6 months of the year, the licensing procedures for Duc Son mine, Thuy An mine (Dong Trieu city), Trung Vuong mine (Uong Bi city) have been completed; continuing to focus on resolving procedures to license the exploitation of Nam Khe mine, Bac Son mine (Uong Bi city); Quang Phong mine (Hai Ha), Hai Tien mine, Hai Yen mine (Mong Cai)...

In addition, procedures have been completed to exploit 2 sand mines with reserves of 18.8 million ^m3 ; focusing on resolving procedures and granting mining licenses with a total reserve of over 12 million ^m3. Excess soil and rock in investment projects; promote solutions, resolve procedures according to authority to maximize exploitation of mine waste soil and rock with a total permitted reserve of 38.8 million ^m3 . Thereby increasing the total volume of landfill materials with procedures, which can be exploited and supplied in the period 2025-2030 to about 180.1 million ^m3 .

According to the review results, the projects implementing construction investment in the period of 2025-2030 have a demand for filling materials of about 115 million ^m3 , focusing on a number of projects with large demand such as the River Road project connecting Ha Long - Hai Phong Expressway with Dong Trieu City, with a demand for filling materials of about 7.6 million ^m3. ; the project of the route connecting from National Highway 279 through the Love Bridge intersection to the Binh Minh Bridge approach road (Ha Long City), the demand for filling materials is about 1.5 million ^m3 ; the project of the route connecting from Hon Net - Con Ong port, from National Highway 18 to Ha Long - Van Don Expressway, the demand for filling materials is about 2 million ^m3 ... Thus, basically, the supply of filling materials in the province has met the needs of the projects.

However, according to the assessment of the professional agency, when organizing and implementing in practice, there are still some problems and limitations leading to low efficiency. In order to exploit and improve the efficiency of using landfill materials, meet the progress, promptly remove and resolve arising problems, on the basis of the direction of the Provincial People's Committee. The province also requires that, along with the development of a circular economy , using excess materials, mine waste soil and rock to serve the landfill projects, departments, branches, localities, investors and related units must study and propose to proactively balance the types and supply sources of landfill materials in the current period and the medium-term period (2026-2030) to ensure suitability, efficiency and feasibility in implementation.
