| 摘 要： | 应用材料力学理论研究下层矿开采的地压特点，并推导矿柱间距计算公式，据此进行矿柱设计。提出用锚杆、锚网支护局部破裂矿柱和顶板，用岩柱置换矿柱，最终崩落岩柱处理采空场。

| Abstract: | At mining lower strata,characteristics of ground pressure are studied by strength theory of materials,and calculating formulas of pillar space are inferred.On the basis of this,pillar design is undertook.With bolt and bolt net,supporting partial cracked pillar and roof is raised,and pillars are exchanged by rock pillars,after all goaf is dealt with by dilapidating rock pillars. |

| Keywords: | Pillar span Support Goaf dealing |
