Chinese authorities say rescuers are rushing to pull out six workers after a mine collapsed in the eastern province of Shandong, leaving another 19 people missing.

The Pingyi county said in a statement Friday that four people were pulled to safety after the gypsum mine owned by Yurong Commercial and Trade Ltd. Co. collapsed.

The county says rescuers have located six people and are working to bring them to safety but added another 19 are missing.

Gypsum is a soft sulfate mineral that is widely used in construction.

The mine collapse comes just days after a landslide from a man-made pileup of construction waste in the southern city of Shenzhen killed one person and left another 75 missing and presumed dead.
