在瓦斯和岩石突出期间,会形成一个界面,这个界面把未受扰动的岩体与被抛出工作面的破碎岩石和瓦斯分开。这个界面向未受扰动岩体的内部移动(图1、2。)我们假定岩石和瓦斯介质为多相的,它由含有微孔的固体和以吸附状态及游离状态存在于微孔中的瓦斯所组成。根据质量守恒、动量守恒和能量守恒的非线性方程组的解,决定了这种介质在其内部存在着产生冲击波的可能性,即所谓应力、速度和密度的突变。在冲击波到达的区域内,可能发生岩石和瓦斯介质的破坏,以及贮存在这里面的瓦斯相的突变。在突变的区域内,介质的特性是由公式(12)中所描述的性质来决定的,它是产生稀疏冲击波的必要条件(相当于图2所描述的情况),这种波引发了突出。在这种情况下,波的热能来自传播冲击波的介质,这就引起了介质温度的降低,这种现象可以在煤和瓦斯突出中观察到。
During gas and rock outburst, an interface is formed that separates the undisturbed rock mass from the crushed rock and gas being thrown out of the work surface. This interface moves towards the interior of an undisturbed rock mass (Figures 1, 2). We assume that the rock and gas media are heterogeneous and consist of a solid containing micropores and a gas that exists in the micropores in an adsorbed and free state Composed of. According to the solutions of the mass conservation, the conservation of momentum and the conservation of the nonlinear equations, the medium has the possibility of generating shock waves inside it, namely so-called sudden changes of stress, velocity and density. Within the area where the shock wave arrives, damage to rock and gas media, and abrupt changes in the gas phase stored there, can occur. In the abrupt region, the nature of the medium is determined by the properties described in Eq. (12), which is a necessary condition for generating a sparse shock wave (corresponding to the situation described in Fig. 2), which causes prominence. In this case, the thermal energy of the wave comes from the medium that propagates the shock wave, which causes a decrease in the temperature of the medium, which can be observed in coal and gas outbursts.
