| 摘 要： | 在分析综放沿空掘巷底板力学环境的基础上，建立了底板力学分析模型，运用弹性理论对底板较大范围内的应力应变分布规律进行了求解，认为综放沿空掘巷的底鼓主要与巷道底板一定深度的岩层及实煤体侧高支承压力有关，从理论上阐述了综放测空掘巷比普通回采巷道更易产生底鼓的力学原理，并探讨了底鼓控制的新途径。 |
| 关 键 词： | 综放沿空掘巷 底鼓 力学原理 应力 应变 支承压力 |

| Abstract: | On the basis of analyzing mechanical situation of floor strata of roadway driving along goaf in fully mechanized sub level caving face, a mechanical model was established. The distribution patterns of stress and strain of floor strata are obtained by the elastic theory. It is revealed that the main affecting factors of floor heave of the roadway are as follows. One is the effect of the high abutment pressure on integrated mass beside the roadway; the other is that the floor strata from floor surface to certain depth is fractured by the tensile strain. The mechanical principle of floor heave of the roadway is examined. And the new control ways of the floor heave are studied. |
| Keywords: | roadway driving along next goaf in fully mechanized sub level caving face floor heave mechanical principle |
