Ha Tu Coal focuses on treating mud

In 2025, Ha Tu Coal Joint Stock Company - Vinacomin was assigned by TKV to exploit 2.5 million tons of raw coal and excavate 44 million ^m3. soil and rock. To complete this task, one of the urgent tasks for Ha Tu Coal is to quickly process more than 2 million ^m3 Mud at the bottom of Bac Bang Danh lake due to the impact of heavy rains and storms in 2024.

Ha Tu Coal Joint Stock Company - Vinacomin has just gone through 2024 with many difficulties. Mining levels could not be expanded according to the annual plan, the order of mobilizing coal seams was changed; there was a lack of dumping area for soil and rock, affecting production progress. From the third quarter of 2024, heavy and prolonged rains, especially the impact of storm No. 3, devastated production levels, causing the amount of water and mud to increase. According to statistics at the time after storm No. 3, the volume of mud accumulated at the bottom of Bac Bang Danh mud of Ha Tu mine was over 2 million m ^3. The concentration of human resources and equipment to pump out water and handle this amount of mud has interrupted the mine's coal production progress.

Mr. Tran Quoc Toan, Deputy Director of Ha Tu Coal Joint Stock Company - Vinacomin said: Facing those difficulties, with the close and drastic direction of the Group, the Company launched a 90-day and night production emulation plan to set specific goals and solutions to complete the assigned tasks. By the end of 2024, the Company had completed 2.35 million tons of coal mining, equal to 87% of the plan at the beginning of the year and 100% of the Group's adjusted plan.

Identifying that the 2025 task will be more difficult when the remaining issues of 2024 have not been resolved, Than Ha Tu has accelerated the progress of handling all stages of work. The important thing to do immediately is to take advantage of favorable weather conditions in the first months of the year, focus on machinery and equipment for dredging work, and completely handle the remaining mud volume of 2024.

In January 2025, the Company completed dredging ^650,000m3 mud. After the Lunar New Year holiday, units focused on production again on the 4th day of Tet and maintained a vibrant competitive atmosphere in the following days.

According to Mr. Nguyen Manh Hung, Head of the Company's Production Control Department, the process of treating moong mud is carried out in order from West to East to proceed with deep exploitation in the Western area according to the plan and exploitation diagram. In order to ensure the completion of moong mud treatment before March 15, 2025 as committed to the Group, in addition to using self-made equipment, the Company is still mobilizing equipment from outsourced partners to participate in the construction to speed up the progress of moong mud treatment. On average, the Company arranges 40 trucks with a load capacity of over 90 tons, 28 trucks with a load capacity of under 90 tons and 7 excavators to operate simultaneously to serve the dredging and transportation of mud from the bottom of the moong to the surface.

With the greatest effort, up to this point, the Company has completed dredging nearly 2 million ^m3. mud at the bottom of the moon and is mining coal at the North Bang Danh moon bed. On average, the unit's coal mining output reaches 8,500 tons per day.

It is expected that before March 15, 2025, Than Ha Tu will dredge and transport over 2.3 million m3 of mud from the bottom of Bac Bang Danh mine.

In addition to the task of dredging and transporting mud, Than Ha Tu also implements storm prevention projects, especially the drainage system. Accordingly, the Company has implemented the construction of 28 projects serving drainage and storm prevention in 2025 according to the plan. At the same time, the unit has also implemented the construction of self-flowing drainage systems around the Bac Bang Danh quarry. For the surface drainage system outside the quarry, the unit dredged settling pits inside and outside the quarry, reinforced dredging of drainage ditches, reinforced drainage systems at waste dumps in Via Tru; at the same time, renovating working floors to lead water to the Company's surface drainage systems.

With the surface water collection area under the self-gravity drainage belts, the Company has built a forced drainage plan with 3 options according to the specific surface water and groundwater volume flowing into the pit. The largest option will arrange 6 pumps with a capacity of 800-1,300m ³ /h in the pit bottom area; the total amount of pumps mobilized is 14 pump systems with a capacity of 600-1,300m ³ /h; the number of pump pipes mobilized is 2,500m.

Learning from the lesson of storm prevention in 2024, Ha Tu Coal is promoting a proactive spirit, preparing the best response plans to natural disasters; ensuring safety for production areas and completing the assigned output plan in 2025 with 2.5 million tons of raw coal.
