摘　　要：应用相关理论知识分析伪俯斜工作面悬跨的顶板在工作面回采过程中顶板的受力破坏情况,推导出判定悬跨的顶板破坏判定准则,有利于摸清该种情况下的顶板垮落情况,对煤矿的安全生产十分有意义。Analyzed the state in pressure of the roof of wide - angle tilt working face by theory, deduced the criterion of determining the state cf roof collapse, which is useful to understand mechanical breakage of the roof and improve the safety of coal mine production.

关 键 词：俯伪斜 压茬长度 端头效应
