Conditions in the area remain dangerous, and the search had to be suspended for several hours because of a second landslide at the gigantic facility in Inner Mongolia’s Alxa League.

On Thursday afternoon, more than a dozen bulldozers, trucks, SUVs and fire engines were seen passing through a remote police checkpoint about 25 kilometers (15 miles) southwest of the mine.

Nearly all personnel were stopped by police and checked for entry approvals before being allowed to proceed along the road leading to the mine.

A police officer said only those with government approval would be allowed access to the area. She said people living close to the mine had been sent to stay in a nearby town.

Security was also tight at another checkpoint in the neighboring region of Ningxia, 15 kilometers (9 miles) east of the mine, with dozens of officers inspecting every vehicle that sought to pass in either direction.

Cranes and other pieces of heavy equipment could be seen, along with covered trucks. It was unclear what the trucks were carrying.
