| 摘 要： | 巷道围岩是由顶板、底板、两帮组成的复合结构体,回采巷道两帮为软弱煤体,直接影响到底板的稳定性。通过数值计算,模拟了两帮煤体强度对底鼓的影响,煤体强度越大,底鼓量越小,反之,底鼓量越大。因此,提出了加固两帮控制深井巷道底鼓的构想,工程实践证明,加固两帮可在一定程度上控制深井回采巷道底鼓。

| Abstract: | The surrounding rock of roadway is a compound structure consisted of roof,floor and sides. The sides of extraction opening are the weak coal mass,which affect the stability of floor directly. Numerical simulation for influence of the strength of side coal on the floor heave is carried out,which shows that the higher the strength of sides coal is,the lower the degree of floor heave is. So the method of reinforcing sides to control floor heave of extraction opening is proposed in this paper. A practical case proves that the floor heave of deep extraction opening can be controlled to a certain degree by reinforcing sides of roadway. |
