| 摘 要： | The problems that the bump of coal and methame in the mine is contraled by the
stress of longwall and that the coal and methane bump in the mine is affected by the physical properties of the coal are analysed and discussed through some specific bump cases. It is shown that the compressive stress, the content of the methane of the coal, and the bump of coal and methane are directly affected by the content of the ash and the volatile of the coal.
