Guodian Datong Power Plant Phase I and Phase II coal yards are located adjacent to urban areas, with rural areas surrounding the yards. During operations and storage at the coal yard, dust is generated on windy days, causing environmental pollution and material losses. In 2015, windbreak and dust suppression walls were installed around the coal yard, with a height of 15 meters. When strong winds pass through these walls, they create airflow disturbances behind the walls, thereby reducing wind speed and significantly decreasing the ability of winds to carry dust. Since its completion 15 years ago, the dust suppression effect has remained significant and the structure remains intact.
