| 摘 要： | 综放开采时,实现顶煤的破碎和顺利放出是放顶煤工作的核心问题,而顶煤的有效破碎又是顶煤放出的前提,同时又是支架选型的依据,并且也是衡量放顶煤效果的主要依据,因此有必要对顶煤的变形破坏机理进行系统分析研究。通过阅读大量有关资料,结合义马耿村煤矿的现场实测,并参考其他放顶煤工作面的观测成果,探讨了综放开采顶煤变形及破断规律。

| Abstract: | Nuclear problem of top coal caving is top coal′s break and caving, effectively break top coal is the precondition of successfully caving, and the bases of supports′ lectotype, and the bases of scaling effect of top coal caving. It′s necessary that system analyses the distortion and rupture mechanism of top coal. By reading large relative data, combining actual measurement in Gengcun mine, Yima, and consulting observation of other top coal caving face, authors discussed distortion and rupture rule of top coal with fully mechanized top coal caving. |
