The landslide reportedly occurred in Nagari Sungai Abu in the province's Solok regency.
Solok Disaster Mitigation Agency Chief Irwan Efendi told local media that 15 miners were killed in the disaster, with three others suffering injuries and 25 others missing, he added.
According to him, more rescuers with heavy equipment have been deployed to evacuate victims in the location.
Unlicensed mines are common across the archipelagic country and a number of accidents have occurred in the past years.
In July, more than 20 people died and over 10 were still missing in a landslide at an unlicensed gold mine in the eastern province of Gorontalo.
