目前国内外对井筒的采动损坏缺乏定量的评价方法，井筒的采动设计与保护容易产生安全隐患。为此，通过总结井筒采动变形、破坏的形式和特点，并根据井壁破坏与围岩变形的关系，主要针对混凝土、钢筋混凝土井壁，建立了科学可行的井筒采动损坏评价方法和指标：以井壁与围岩的竖向变形关系为主要评价指标，分别建立了表土、基岩段井壁竖向压缩(拉伸)变形破坏的计算公式。通过井筒采动损坏实例分析，印证了该评价方法和指标的可靠性。研究成果解决了井筒采动损坏的安全性评价问题，为井筒煤柱开采的安全设计提供了可靠的技术保障。

At present,there is lack of the quantitative evaluation method for mining damage of shaft at home and abroad. It is easy to produce hidden danger for shaft′s mining design and protection. Thus,the form and characteristics of shaft′s mining damage are summarized. And also,according to the relationship of shaft lining damage and wall rock deformation,the scientific and feasible evaluation method and index of mining damage are established which aims at the concrete and reinforced concrete shaft lining. With the relationship of vertical deformation between shaft lining and wall rock as the main evaluation index,the calculation formula of vertical compression deformation damage of surface soil and bedrock section shaft lining are established separately. Through the example analysis on shaft mining damage,the reliability of the evaluation method and index are corrob-orated. The research solves the problems in safety evaluation of shaft mining damage,and supplies the safe and reliable techni-cal support for safety design of shaft coal pillar mining.
