METHOD FOR SEISMIC AND ACOUSTIC MONITORING OF LONGWALL FACE AREAS IN COAL MINES
2021
The article presents the experimental data of seismic and acoustic monitoring in a fully mechanized longwall mining face. The predictors of the rock mass behavior are selected to be the acoustic emission activity and the increase in the pulse recurrence rate at the same time in the neighbor roof support unit. Crack formation in the longwall mining face zone is calculated.
