一侧采空巷道稳定性不仅与支承压力分布有关，而且与煤体受破坏程度有关。本文提出了能综合反映上述两方面影响的“等效稳定性系数法”，并推导给出了等效稳定性系数的计算式。
The stability of roadway on one side is not only related to the supporting pressure distribution, but also to the degree of destruction of coal. In this paper, the “equivalent stability coefficient method” that can comprehensively reflect the above two influences is proposed and the calculation formula of equivalent stability coefficient is deduced.
