中文摘要：

将工程实践中接触到的留巷顶板分为厚层直接顶、薄层直接顶和无直接顶3种类型,利用叠加连续层板模型,考虑巷帮煤体承载作用和导致顶板垮落诱因,得出了3种顶板条件下的巷旁支护阻力计算公式。研究表明,巷帮煤体、充填区域顶板承载性能的提高有助于降低巷旁充填体支护阻力。随直接顶厚度的减小,充填体支护阻力反而增大。基本顶层位不同,顶板垮落诱因不同。厚层直接顶时,顶板垮落为自重引起;薄层直接顶时,顶板垮落为基本顶上位岩层作用所致。

英文摘要：

The common field gob-side entry retaining roofs are divided into three types,i.e.thick immediate roof,thin immediate roof and without immediate roof.Through utilizing the continuous laminate model and considering the factors of the support effect of the coal side in the roadway,the incentives of roof caving,etc.,the calculation formulas of roadside support resistance under three kinds of roof conditions are obtained.According to the formulas,the increase bearing ability of coal side and the roof of filling areas benefit to decrease the support resistance of filling body beside roadways.With the decrease of the thickness of immediate roof,the support resistance of filling body increase.The roof collapse＇s incentives would vary from different layers of immediate roof.Gravity causes the thick immediate roof＇s collapses;and on the other hand,the movement of upper rock layers causes the thin immediate roof＇s collapses.
