煤和瓦斯突出预测煤体结构指标计算方法的探讨

Study on the Calculation Method of Coal Structure Index for Prediction of Coal-gas Outburst

煤体结构类型是煤和瓦斯突出预测的重要地质指标，笔者在对煤体结构类型与瓦斯参数关系研究的基础上，提出突出煤层煤体结构有效厚度的概念和计算方法，并以河南平顶山矿区为例，进一步探讨了突出煤层煤体结构指标临界值的计算方法，为煤体结构指标定量计算提供了新的研究方法。

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.
