Question 1

Correct Answer:

Verified

Even though mining stopped decades earlier,sudden subsidence from the collapse of mine support structures,or from tunnels caving in,is still possible.You might want to know whether old mine tunnels are underneath the property,where the tunnels are located,the locations of coal support pillars in the old mine,and the history of mine-related subsidence in the region.You'd probably want to know what types of mitigation strategies,if any,have been employed to support the old mine shafts and tunnels.
