| 摘 要： | 运用煤层塑性软化理论，通过解析分析，导出了采煤工作面附近煤层和顶板的变形与应力分布规律，运用极值点失稳理论，给出了煤体开始软化时的采空区跨度与顶板所受压力之间的关系，计算了采煤工作面产生冲击地压时采空区跨度与载荷间关系。采煤工作面冲击地压的分析方法可推广应用于巷道和煤柱冲击地压的分析，为煤矿安全生产和预防冲击地压提供一定的理论参考。

| Abstract: | According to analytical solution, the plastic soften theory on coal layer is used to solve the deformation and stress distributions of coal layer and roof along working surface. Based on limit-point instability theory, the relation between roof press and opening spans is put forward while coal body softens, the relation between the opening spans and loads is calculated while rockburst can happen. This analytical method of rockburst on working surface can be popularized to analyze tunnel and pillar rockburst, which provides a theoretical consultant for safety and production on coal mine and forecast of rockburst. |
