杆柱适应于各种不同顶板岩层结构与岩石性质的房柱法中,随着应用条件的不同,杆柱作用原理亦因之各异。必须在充分研究了在各种不同条件下的杆柱作用原理,矿山压力大小,杆柱顶板的变形、破坏的力学性质的基础上才能在确地确定杆柱支护参数与矿房宽度的计算方法。 Pole to adapt to a variety of roof rock structure and rock properties of the Housing and Pillar Act, with the application of different conditions, the principle of the pillars also vary. It is necessary to make sure of the calculation of the pole support parameters and the width of the mine house based on the full study of the principle of the pole under different conditions, the pressure of the mine, the deformation of the pole roof, and the mechanical properties of the destruction method.
