This study reveals the general working law of concrete-filled steel tubular (CFST) arch supports by exploring the experimental strain data based on structural stressing state theory. Firstly, the tested strains are transformed into the generalized st

The shotcrete technology (application of a concrete layer) is widely used in coal mines. The applied layer of shotcrete to the underground workings support, changes the load capacity of the entire supporting system (and its elements). The coating of

Steel arch supports are used widely in long workings in coal and ore mines. Their displacements are in difficult conditions often comparable with the size of the structure. Changes in the geometry of whole arch support including changes in the shape

Open U-shaped steel arch supports are commonly used in large-section static-pressure roadways in coal mines that are more than 900 m deep; however, it is very difficult to control floor heave of roadways. In this paper, a U-shaped steel closed suppor
