| Abstract: | The type of coal structure is one of important geological indexes for prediction of coal-gas outburst. Based on study of the relationship between gas parameters and coal structure type, the concept of effective thickness of coal structure and its calculation method are put forward. Taking Pingdingshan mining district for example,calculation method for critical values of the coal structure index in outburst coal seam is discussed. This provides a new approach of quantitative calculation for coal structure index. |
