Model of calculation On the basis of the past experience and the practical conditions, some hypothesis are established for the FEM model as follow: (1) the stress-strain relationships is satisfied to the basic hypothesis of plain strain problem; (2) the anchor bolt and lining are belong to elastic materials, but the rock mass and soften joints are considered as elastic-plastic medium; (3) the normal of the isotropic surface is orthogonal to the axis of underground opening.
The deformation modulus of interfaceequals to 500kpa, equals to 400kpa andequals to 50000kpa, other material parameters are shown in Tab.1.

Magnetorheological fluid is widely concerned by scientists from many fields such as physics, chemistry, mechanics, mathematics, materials science and mechanical engineering and has important research value[1-3].
So the removal of material is closely related to the magnetic field.
