Abstract
The parameters of physical, mechanical, rheological and water properties of clay rock in the Kara-Keche coal quarry are presented. It is found that in relation to water, gray clay is a swelling-proof and impervious rock. Its presence at the boundary of slip line surface contributes to the activation of landslide phenomena in the open-pit sides. It is determined that gray clay has a pronounced rheological ability to develop plastic flow deformations. The dependence of effective viscosity of gray clay on humidity value was revealed. It is shown that theoretical and experimental values of effective viscosity are in good agreement.
