| Abstract: | The paper is based on demolition of dangerous rock mass of rock roof above karst cave in Fenghuang mountain in Fanchang country Anhui province by blasting. The numerical simulation method is applied for analysis of the stability of the remnant rock mass above karst cave under impact loading. The stress state and deformation degree of remnant rock mass above karst cave under different time are obtained. Scientific evidence is provided for design of construction program. |
| Keywords: | remnant rock mass karst cave numerical simulation |
