Abstract:

The relations are determined systematically between the burst tendency and water content, the water content and porosity in coal seam by experiment. It is found that the burst tendency of coal seam depends inversely on the water content, and it is most sensitive in original water content. The saturated water content in coal seam depends on porosity in coal. A reliable quantitative basis is provided for preventing rockburst in coal mine by using water injection method.
