Mechanism of Dynamic Failure in Roadways with Thick and Competent Roof Strata: A Case Study

Mechanism of Dynamic Failure in Roadways with Thick and Competent Roof Strata: A Case Study

Rock and coal dynamic failures have a higher chance to occur when thick and competent roof strata are presented, which can build up a high level of energy. This paper studied the fracturing characteristics of the competent roof strata during longwall face retreat and their effects on roadways’ stabi...
