摘要
以顶板淋水对巷道围岩变形破坏的影响和防治为对象开展探究,结合具体工程实际,在分析顶板淋水对巷道围岩影响的基础上,通过数值模拟条件,进一步探究顶板淋水对巷道围岩塑性区、应力和位移变化的影响,进而提出针对性的巷道联合支护方案,为顶板淋水条件下巷道的长期安全使用提供帮助。
The effect of roof water spraying on deformation and failure of roadway surrounding rock and its prevention were explored.Combined with specific engineering practice,on the basis of analyzing the effect of water spraying on the surrounding rock and through numerical simulation,this paper further explored the effect of roof water spraying on the plastic zone,stress and displacement changes of surrounding rock of the roadway,and then put forward a targeted combined support scheme of the roadway,so as to provide help for the long-term safe use of the roadway under roof water spraying conditions.
