Rockbolts as reinforcing elements under dynamic impact of rokbursts
Original language description
Due to strong impacts of rockbursts in Ostrava ? Karvina coalfield which affect especially roadways and cross-cuts of longwall panels it is necessary to strenghten standard steel breakthroughs support. Using of reinforcing complementary bolts seems to bevery effective. Different varieties of a number and location of such rockbolts have been analysed and compared from the viewepoint of the stability under dynamic events on the base of 3D mathematic modelling. The instrument of computer modelling has been FEM applied by ANSYS code. It deals with shape and nature of deformation of steel support, strain and deformation of reinforcing bolts, critical energy by which a permanent strain is caused, influence of interaction of adjacent rock on the above mentioned characterisics. Recommendation for number and location of reinforcing complementary bolts is also contained.
