| Abstract: | Fast Lagrangian is a new type of numerical calculating method. This paper introduces the basic principle and analyzes procedure of Fast Lagrangian method; Then this method is used in the calculation of bolt support on coal goal, and deformation of goaf is compared before and after bolt support. The calculating result shows that the bolt support has obvious effect on controlling the displacement of rockstrata vertical orientation. |
