| 摘 要： | 工作面过空巷一直是未能很好解决的技术难题。以欣源矿30101综采工作面过走向空巷为工程背景，分析了走向空巷变形破坏原因，得到了空巷顶板不发生离层的充填体最小支护阻力。根据充填体强度与顶板下沉的关系和高水材料强度随时间的关系，确定采用高水材料水灰比为8∶1。现场应用表明:采用此水灰比的充填体能有效支撑空巷顶板，不影响正常回采，现场应用效果良好。

| Abstract: | Working through the empty alley has always been a technical problem that has not been solved very well.Taking the 30101 fully mechanized mining face of Xinyuan Mine to go through the empty roadway as the engineering background，the reasons for the deformation and failure of the empty roadway were analyzed，and the minimum support resistance of the filling body without the separation layer of the empty roof was obtained.According to the relationship between the strength of the filling body and the sinking of the roof and the strength of the high water material with time，it was determined that the water-cement ratio of the high water material was 8∶ 1.The field application shows that the filling body with this water-cement ratio can effectively support the roof of the empty road，and does not affect the normal mining，and the field application effect is good. |
