Study on deformation and failure characteristics of overlying strata with thick loose layers and thin bedrock based on Hoek-Brown criterion

Study on deformation and failure characteristics of overlying strata with thick loose layers and thin bedrock based on Hoek-Brown criterion

The mechanics parameters of rock mass in Wulanmulun mine are determined on the basis of the experimental data measured in the laboratory and applied Hoek-Brown criterion in this paper.On this basis the failure characteristics of overlying strata caused by coal mining are studied through FLAC<sup&...
