| 摘 要： | 通过对受二次采动影响处于软弱破碎煤岩区动压巷道的长期观测，运用数值模拟、现场监测和工程类比的方法，对厚煤层沿空掘巷底臌控制进行研究，分析了底臌的原因，从而得出以巷道整体为对象，用锚杆对底臌进行有效合理控制的方法，并将该法应用于工程实践中，取得了良好的技术经济效果。

| Abstract: | Through the long-term investigation of the laneway of dynamic pressure influenced by second mining, the floor heave control of road driving along next goaf in high seam is investigated quantitatively with the method of numerical simulation, locality monitor and engineering analogy. The reason of floor heave is analysed and an effective method of using anchor stick to control the floor heave is obtained. This method has been applied to the engineering practice, showing nice technical and economic effect. |
