Prediction and evaluation on building damages of strip pillar mining under villages;

Determination of surface subsidence prediction parameters for strip pillar mining

Based on the specific geological and mining conditions and the status of Nanying buildings,the results show that it is feasible and reasonable to extract the coal reserves under village using strip pillar mining method in this coal mine,and the strip pillar mining plans and their parameters were presented.
