| 摘 要： | 大量观测和模拟实验表明，薄基岩在厚沙覆盖层作用下的整体切落是顶板破断运动的主要方式。本文论述了对顶板破断运动及破断后运动的控制，指出保证足够的初撑力和采空区一定充填状况是控制要点。并进一步分析了基岩厚度、采高、推进速度对顶板破断的影响。

| Abstract: | A number of in situ Observation and modelling test show that main way of koof breaking movement is intact shear fall of all overburden stratum.Control of roof breaking movement is described,pointing out that addquate setting load of the supports and adequate filling height in the mine goaf are key points of controlling method.The effect of basic rock thickness,mining height and advancing speed on roof breaking is analyzed. |
