Abstract: AbstractEnsuring roadways stability in hard coal mines is one of the main challenges faced by engineers. A changeable geological structure have caused the roadway’s conditions to vary, thus influencing its stability. One of the causes of those changes is the presence of a previously undiscovered fault zone (small faults crossed the roadway) within which a significant convergence or support deformation may occur.The paper presents the impact of low throw faults on the degree of convergence of roadways. Convergence is determined for two roadway...
