基于能量方程的含瓦斯煤岩动力灾害分类

Classification of Coal-rock Dynamic Disasters Based on Energy Equation

为了有效辨识深部含瓦斯煤岩动力灾害,基于能量方程,依据发生动力灾害的能量源将含瓦斯煤岩动力灾害分为三大类:瓦斯主导型、地应力主导型和冲击诱导型。又进一步将瓦斯主导型分为瓦斯突出型、冲击-突出型;地应力主导型分为压出型和冲击-压出型;冲击诱导型分为冲击诱导突出和冲击诱导压出型。对含瓦斯煤岩进行科学分类不仅有利于深入理解动力灾害发生、发展过程,而且对深部煤岩动力灾害的有效防治有指导性。

Effective identification of dynamic disaster is important for preventing and controlling dynamic disaster. Aims to classify dynamic disaster of coal containing gas based on energy equation.The result show that dynamic disasters is classified to 3 types: gas leading type, stress leading type and bumps inducing type. The gas leading type is divided into gas outburst type, bumps-outburst type.Stress leading type is divided to extrusion type and bumps-extrusion type. Bumps inducing type is divided to bumps inducing outburst type and bumps inducing extrusion type. It is favorable for understanding dynamic disaster deeply to classification of dynamic disaster which is significance for predicting and preventing coal and rock dynamic disaster effectually in deep mine.
