Abstract

Abstract: Coal mining can often encounter with faults. Based on beam model, stress analysis and ANSYS numerical simulation are made for the normal fault of coal rock stratum. The fault stress value is considered to have relation with the load concentration and inclination angle of the fault. The ANSYS numerical analysis has draw a conclusion that is basically in conformity with that by the theoretical analysis of beam model, and therefore, can be used as reference for the support of broken roof.

Key words: Beam model, Fault, Primary breaking, Periodical breaking, ANSYS
