| Description | Various types of weak swelling strata occur in many mine areas in Turkey such as Soma-Işiklar, Alpagut-Dodurga, Soma-Darkale etc. Excavations in these strata become badly deformed and deteriorated by the violent swelling rock pressure, so that frequent repairs are needed, influencing the ongoing production and mine construction, greatly. Therefore, it is of vital importance to research on rock pressure and supports in drifts built in weak swelling strata. In this study, in-situ measurements on test supports were conducted to determine the rock load around the opening on steel set supports for the main drift in Soma-Işiklar Colliery of Turkey. This chapter describes in-situ measurements on test supports to determine the rock load around the opening on steel set supports for the main drift in Soma-Isiklar Colliery of Turkey. It explores rock loads around the openings for the main drift using back analyses of the rock pressure method and compares results with the direct load measurement results in Soma-Isiklar Colliery of Turkey. A technique has been developed for the back analyses of rock pressure by Kovary and is known as the integrated measuring technique. From the support point of view the concept of weak swelling strata should be based on the characteristics of rock pressure of the swelling strata and the conditions for their formation. The deformation of the drift caused by the swelling pressure is mainly due to the physical and mechanical characteristics of weak swelling rock strata and nature of their behaviour.
