高空隙率、低透氣性使構造煤能夠保持較高的瓦斯壓力;破碎性、 「隔離」作用及「氣墊」作用,使構造煤抵禦外力作用的能力大大降低;構造煤變形幅度大的特性,為瓦斯的迅速解吸、放散和快速流動創造了條件;構造煤薄弱分層或「通道層」的存在,則為煤與瓦斯突出的初始激發和持續發展奠定了基礎;上述因素的共同作用,影響和制約了煤與瓦斯突出的強度和分佈.盡管如此,一定厚度的構造煤的存在只是發生煤與瓦斯突出的必要條件和有利條件,而非充分條件In this paper, high heat penetration into a moving particulate bed is described mathematically with a comprehensive heat and mass transfer model. the distribution of gas velocity and pressure, the temperature field of gas and solid in the moving particulate bed are examined for different conditions. the results show that thermal penetration into the moving packed - bed particles by fluid flow in porous media is high only in the position near the gas entrance. the thermal penetration thickness tends to increase with the fluid flow velocity and decrease with the particle moving velocity. in the region of thermal penetration, the porosity of solid bed has significant effect on gas field and pressure loss. it is feasible to reduce the gas pressure loss by a larger width / height packed bed in design and operation. the correspondence between thermal infection depth and particle bed height would be helpful to keep high oapacity of reactor and reduce the cost of operation
