预防采空区气体冲击灾害的密闭墙研究

On sealing wall to prevent air bursting disaster in gob areas

建立了采空区永久密闭结构的计算模型,分析了密闭墙在气体的冲击作用下的受力状态,得到了其结构参数与受力状态的关系。利用有限差分软件FLAC3D进一步对永久密闭的强度进行了演算,研究成果在现场实际应用中取得了很好的效果。

With a calculation model set up for permanent sealing wall structure used in gob area, the stress state of the sealing wall structure under the condition of air bursting stress is analyzed and the relations between the structure parameters and the state of stress is obtained. The strength of the permanent dealing structure is further calculated by finite difference software and the research results achieve success in actual field application.
