摘要： 以淮北临涣矿区为例，在详细调查分析了破裂井筒的矿井水文地质与工程地质条件及其它背景资料的基础上，根据矿区底含土体及煤系基岩风化带变形破坏的影响因素及形成过程，本文首次论论了岩土体变形破坏的四个发展阶段和井筒破裂的四种模式及其间的关系，并揭示了井筒破裂的，从而为防治井筒破裂和评价井筒稳定性提供了依据。

Abstract: Based on the hydrogeological and engineering condition of rupture shaft and other background information of Linhuan mine area, hydrogeological model of this mine is estab1ished, the influence factors and forming process of deformation and destroy of the bottom aquifer soil and the weathered basement are analyzed. The four development stages of deformation and destroy of rock-soil mass and four models of shaft rupture are first put foreword. Some regularites of shaft rupture are obtained. Mechanism of shaft rupture s exposed. This study provides scientific data for controlling the shaft rupture and evaluating the stability of shaft.
