根据关于突出机理的“球壳失稳”理论提出了预测煤层突出强度的指标,通过多次突出模拟试验,用多元回归方法建立了预测突出强度的线性函数,实验证明:煤样的初始释放瓦斯膨胀能和软煤厚度可以准确地预测煤层的突出强度。 According to the theory of “instability of the spherical shell” of the salient mechanism, the index of predicting the salient intensity of the coal seam is put forward. Through multiple salient simulations, the linear function of the predicted salient intensity is established by the multiple regression method. The experiment proves that the initial Release of gas expansion energy and soft coal thickness can accurately predict the salient strength of coal seam.
