2019-12-1 The following conclusions are drawn from the field monitoring data, which provide valuable information to better understand the load transfer mechanics associated with longwall retreat mining. Mining depth is a key factor controlling the range of mining-induced stress. The greater the depth, the greater the range of the mining-induced stress.
