摘要
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。
The indexes of forecasting coal and gas outburst intensity are presented according to the spherical shell losing stability theory about outburst mechanism. In laboratory, outburst simulated tests have been carried out for many times. And the linear equation which can be used to forecast outburst intensity has been established by means of pluralistic regression. It is proved by the tests that the outburst intensity can be forecasted by the expansion energy of initial releasing gas from coal and by the thickness of soft coal.
