地下岩体在开采之前，由于自重和构造所引起的应力是处于平衡状态的，当掘巷道或者进行回采工作时，就破坏了原来应力的平衡状态，使岩体内部应力重新分布，具体表现在巷体周围的煤、岩体产生移动、变形，直到煤和岩体内部形成新的应力平衡状态为止。在煤的开掘过程中，由于采掘活动引起巷道围岩应力集中和重新分配，为了防止围岩变形遭到破坏，需要对围岩进行支护和加固。本文就大断面煤层沿空巷内支护加固技术进行研究，以便为煤矿在开采过程中积累一些技术和经验。

Before underground rock mining, because the stress caused by the weight and structure are in equilibrium, when excavating the roadway or carrying out mining, the balance of the original stress will be destroyed and the internal stress of rock will be redistributed, whose specific performance is that the movement and deformation of the coal and rock around the roadway happens until the new stress equilibrium of coal and rock shaped. In the process of digging coal, due to the concentration and redistribution of roadway surrounding rock caused by extractive activities, in order to prevent the destruction and deformation of surrounding rock, the support and reinforcement of surrounding rock is necessary. In this paper, the large coal section gob gateway support reinforcement technique is studied to accumulate the technology and experience in the coal mining process.
