| Abstract: | Based on in-situ observations and analoque maferial modelling, the finite element mothod was used to study the process of movement and destroying of the strata and ground pressune phenom ena in condition of slice mining and caving mining, and analysed the shructural charectenristics of immediate roof and main roof. Its conclusion rous proved in face7131, and played an rmportant role in caving mining method. |
