To solve the challenges in supporting fractured roof coal seam roadways, a rock layer detection recorder was used to conduct tests on the coal seam roadways at Xindeng mine. The analysis focused on the evolution characteristics of surrounding rock fractures. The R value for the direct roof rock and the β coefficient for roof fragmentation were introduced as evaluation indicators for roadway surrounding rock stability. The surrounding rock was categorized into four types: easy to support, relatively easy to support, relatively difficult to support, and difficult to support. Specific support parameters were provided for each category. Zoned support technology was applied in the gas drainage chamber of +90 North wing of Xindeng mine, achieving excellent support results. The study shows that the state of the roof surrounding rock is zoned, with the shallow fractured zone, followed by the fractured-fracture mixed zone, the developed fracture zone, and the intact surrounding rock zone. Through fracture analysis, it is found that the width of the roof fracture zone gradually expands to the deep surrounding rock over time, and the number of fractures also increases. The existing support cannot effectively control the continuous deterioration of the surrounding rock integrity.

为解决破碎顶板煤层巷道支护困难的问题,采用岩层探测记录仪,在新登矿煤层巷道进行测试,分析围岩裂隙演化特征,引入巷道直接顶岩性R、顶板破碎系数β,将其作为巷道围岩稳定性的评价指标,并将巷道围岩分为支护容易区、较容易区、较困难区和困难区4类,针对每一类围岩给出具体支护参数;然后运用分区支护技术在新登矿+90北翼瓦斯抽放硐室进行现场应用,支护效果良好。研究表明:顶板围岩状态呈现分区性,由浅部向深部可依次划分为浅部破碎带、破碎裂隙混合带、裂隙发育带和围岩完整带;通过裂隙分析指标得出,顶板裂隙区宽度随时间不断向围岩深部扩展,裂隙数量逐渐增多,原有架棚支护无法有效控制围岩完整性的持续劣化。

为解决破碎顶板煤层巷道支护困难的问题,采用岩层探测记录仪,在新登矿煤层巷道进行测试,分析围岩裂隙演化特征,引入巷道直接顶岩性R、顶板破碎系数β,将其作为巷道围岩稳定性的评价指标,并将巷道围岩分为支护容易区、较容易区、较困难区和困难区4类,针对每一类围岩给出具体支护参数;然后运用分区支护技术在新登矿+90北翼瓦斯抽放硐室进行现场应用,支护效果良好。研究表明:顶板围岩状态呈现分区性,由浅部向深部可依次划分为浅部破碎带、破碎裂隙混合带、裂隙发育带和围岩完整带;通过裂隙分析指标得出,顶板裂隙区宽度随时间不断向围岩深部扩展,裂隙数量逐渐增多,原有架棚支护无法有效控制围岩完整性的持续劣化。

To solve the challenges in supporting fractured roof coal seam roadways, a rock layer detection recorder was used to conduct tests on the coal seam roadways at Xindeng mine. The analysis focused on the evolution characteristics of surrounding rock fractures. The R value for the direct roof rock and the β coefficient for roof fragmentation were introduced as evaluation indicators for roadway surrounding rock stability. The surrounding rock was categorized into four types: easy to support, relatively easy to support, relatively difficult to support, and difficult to support. Specific support parameters were provided for each category. Zoned support technology was applied in the gas drainage chamber of +90 North wing of Xindeng mine, achieving excellent support results. The study shows that the state of the roof surrounding rock is zoned, with the shallow fractured zone, followed by the fractured-fracture mixed zone, the developed fracture zone, and the intact surrounding rock zone. Through fracture analysis, it is found that the width of the roof fracture zone gradually expands to the deep surrounding rock over time, and the number of fractures also increases. The existing support cannot effectively control the continuous deterioration of the surrounding rock integrity.
