Abstract: In order to protect the safety of the fan by mining, the paper studied the mechanism of mining subsidence damage from uneven subsidence of the fan foundation and slope of the fan support member, according to the characteristics of fan in wind farm, and discussed the measures controlling the surface subsidence caused by mining under fan, and proposed the rectification and reinforcement measures for fan foundation. At last, this paper, combining with the coal mining under fan in a wind farm south of China, analyzed mining subsidence effects and fan foundation rectification and reinforcement measures.

Key words: mining under fan, uneven subsidence, slope, protective measures
