在大多数关于煤与瓦斯突出本质和机理的文章中都指出,机械能在突出中起主要作用。为了解释发生突出的原因,学者们提出了一些假说。这些假说基本上分成三种。其中,每一种假说对什么因素在激发突出中起积极作用,看法上都各有特点。 矿井发生突出是由于岩层压力、包含在煤体中的瓦斯和煤层的物理机械性质相互作用的结果。矿山压力是激发突出的第一能源,岩层的透气性和瓦斯压力分布以及煤的疏松程度都取决于它。 仅仅矿山压力的作用就足以引起突出发生,当包含在煤体中的瓦斯从煤体中涌出时,应该具有很高的速度,起码的压力(约30～50MPa)。此外,还必须进行吸附瓦斯和游离瓦斯之间的质量交换。煤的结构决定煤的强度、瓦斯涌出速度和瓦斯含量。 因此,矿山压力是引起突出的基本因素,而瓦斯是实现突出的基本因素。煤层结构给释放矿山压力和瓦斯的势能提供了便利条件。 只有游离瓦斯参与突出。要形成突出危险局势,必须有大量处(?)高压状态的游离瓦斯。为了准确地
In most articles on the nature and mechanism of salvaging coal and gas, it is pointed out that mechanical energy plays a major role in salience. In order to explain the reasons for the outstanding, scholars put forward some hypotheses. These hypotheses basically fall into three categories. Among them, each of the hypotheses on what factors play an active role in highlighting, the views have their own characteristics. Outbursts in the mine are the result of the interaction between the formation pressure and the physical-mechanical properties of the gas and coal seams contained in the coal. Mine pressure is to stimulate the prominent first energy, rock permeability and gas pressure distribution and the degree of loose coal depends on it. Only the effect of mine pressure is enough to cause prominence. When the gas contained in the coal gushes out of the coal, it should have a very high velocity and minimum pressure (about 30-50 MPa). In addition, mass exchange between adsorbed gas and free gas must also be performed. The structure of coal determines the strength of coal, gas emission rate and gas content. Therefore, mine pressure is the basic factor that causes prominence, and gas is the basic factor to achieve prominence. The coal seam structure provides convenient conditions for releasing the pressure of the mine and the potential energy of the gas. Only free gas is involved in highlighting. To form a prominent dangerous situation, there must be a large number of (?) High pressure free gas. In order to accurately
