【摘要】：为提高综掘巷道的掘进效率、改善支护工艺,提出一种用于综掘巷道迎头顶板支护和自移式迈步式超前支护装备。分析巷道迎头顶板的力学特性和超前支护装备的工作原理,建立超前支护-顶板系统的力学模型,利用结构力学和材料力学相关理论建立顶板的挠度方程,借助计算机辅助软件求解顶板的变形规律。使用Ansys仿真软件对顶板及支护设备的变形量进行仿真。设计了超前支护实验样机,结合模拟顶板对超前支护装备的支护特性进行了模拟实验。实验结果表明,在超前支护装备的作用下,巷道顶板得到了有效支护,顶板变形量较小,其具有较高的工程应用价值。
[Abstract]:In order to improve the driving efficiency of roadway, improve the supporting technology, proposes a method for digging tunnel roof support and self moving step type forepoling equipment. The analysis of mechanical characteristics of tunnel roof and advance the working principle of supporting equipment, establish the advanced mechanical model supporting roof system. The establishment of the roof deflection equation using structural mechanics and material mechanics theory, the deformation law of computer aided software for solving the roof. On the roof and supporting equipment deformation is simulated by using Ansys simulation software. The design of advanced support test machine, combined with the simulation of roof has carried on the simulation to the leading support equipment support characteristics. The experimental results show that in the leading support equipment under the action of roadway roof effectively supporting the roof deformation is small, it has high application value.
