摘要
岩层控制理论是瓦斯灾害防治的基础之一。介绍了上覆岩层运动后的应力分布、关键层理论和关键层运动。结果表明上覆岩层运动后的应力分布对煤与瓦斯突出有重要影响,关键层运动对邻近层瓦斯涌出和采空区瓦斯涌出有重要影响。因此,可以利用岩层控制理论指导瓦斯抽采和预防煤与瓦斯突出的发生。
Strata control theory is one of the bases of gas disaster control. The stress distribution of the strata movement, the key strata theory and the key strata movement were introduced. The results indicated that the stress distribution of the strata movement influences coal and gas outburst greatly,and the key strata movement affects importantly neighboring layers of the gas emission and goal gas emission. Hence, strata control theory can be used in gas extraction and control of coal and gas outburst.
