Research on the mechanism and control measures of rock burst in steeply-inclined and extremely thick coal dike

A cantilever beam model which induces the rockburst is established aiming at the especial mode of occurrence of the steep seam and mining way. Then a corresponding comprehensive control measure is proposed by the result of the model that the energy inside the middle rockwall is proportional to the cube of effective bending length. The energy-saving condition can be changed by the deep hole blasting on the ground at the range of +500～+736m along the rockwall. besides, the rockburst tendency will reduce by the measures which is composed of water pouring and deep hole blasting at range of +475～+515m. At last, it indicates that this series of measures reduce the risk of rockburst obviously with the technology of ARAMIS M/E.
