摘　　要：阐述了暗空场充填保护地表构筑物的机理;推导了地表构筑物不发生破坏的充要条件;推求出在充分采动与非充分采动条件下,构造应力型与自重应力型破坏的暗空场充填率公式,可用以指导安全、经济地保护地表构筑物的设计。The paper describes the mechanism of protecting the surface buildings by filling the blind mined-out area, deduces the necessary conditions for the surface building not to be destructed and gives out the formulas for the blind minedout areas of tectonic stress and self-gravity stress destruction types at full extraction and non-full extraction conditions, which can be used in guiding the design for safe and economic protection of surface buildings.

关 键 词：地表构筑物 暗空场 充填率 充分采动
