The influence of the disturbing effect of roadways through faults on the faults’ stability and slip characteristics

Abstract

	•The mechanical model of fault activation induced by roadway excavation was established with the plane strain theory.
	•The loading rate relationship between the numerical simulation model and field scale was developed.
	•The influence of fault angles and roadway excavation speed on the fault instability was investigated.

Keywords
