Hence, stratacontrol theory can be used in gas extraction and control of coal and gas outburst.
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。

Stratacontrol system belongs to grey system because its position, structure and boundary condition are difficult to describe precisely.
岩层控制系统的状态、结构和边界条件难以精确描述,属本征性灰色系统。

Finally, the stratacontrol observation dat shows that gateway deformation was under control by this plan, and the better economic benefit was obtained.
