Vang Danh Coal Joint Stock Company has focused on applying new technologies into production with a view to both increasing labor productivity and protecting the environment. An important milestone was placed in late 2017 when Czech engineers successfully transferred coal mining technology with a synchronized mechanized furnace system to Vang Danh Coal Joint Stock Company. It has currenlty been Vang Danh Mine’s first mechanized furnace which produces the largetst output (nearly 300,000 tons/year).With 16 years working in this field, worker Nguyen Van Hoi at the KT11 workshop is proficiently operating the automatic anti-skid system in a synchronously mechanized furnace.After nearly 4 years of being putting into operation, the first mechanized market furnace has so far been transformed 3 times. In 2021, the coal mining output from mechanized kilns reached approximately 580,000 tons/year, accounting for 20% of underground coal production.In late 2019, Vang Danh Coal Joint Stock Company put the EBH-45 excavator into operation. This is one of Vietnam National Coal and Mineral Industries Group's fastest excavators as it digs more than 47.7 meters monthly, or an increase of more than 15 meters compared to the old mining technology.The technology of mechanizing the bottom-buffering machine, which works to break up the coal and stone materials attached to the bottom of the wagon, has been applied at Vang Danh Coal since 2018. It has played an important role in reducing the number of labors.The automatic wind closing technology has been applied in most of the company's main furnace doors. This technology helps the company to reduce 8 labors responsible for opening and closing louvers each shift, contribute to improving the safety of people and vehicles when going through the louvers and reducing wind loss.In January 2022, Vang Danh Coal Joint Stock Company put the underground water cooling system into operation. The project has a total investment capital of more than VND 19.2 billion. This is among the first mines in the Group to operate a circulating cooling system to help improve microclimate conditions, ensuring a good working environment for employees.
