| 摘 要： | 分析了造成竖井移动和变形的原因，认为井筒的破坏不仅与保护煤柱的大小有关，而且还与煤层倾角岩性、弱面及地质采矿条件有关，在此基础上，提出了合理的井筒保护措施。

| Abstract: | This paper analyzes the causes of the displacement and the deforma ti on of the vertical shaft, holding that the damage of the pit shaft relates to no t only the size of the protective coal column but also the obliquity, lithology, weak surface and geological mining conditions, and based on these, puts forward some rational protective measures for the pit shaft. |
