| 摘 要： | 贺西煤矿3#煤层在回采过程中,瓦斯尾巷底鼓非常严重,严重影响下一工作面的正常使用,致使采掘衔接紧张,本文以3#煤层工作面瓦斯尾巷为背景,深入分析瓦斯尾巷底鼓量大的主要因素,剖析巷道底鼓机理,以FLAC3D数值模拟为主要手段,针对实际情况选择合理底鼓控制措施。工业性试验结果表明,工作面瓦斯尾巷巷道支护状况良好,底鼓问题基本得到了解决。

| Abstract: | The floor heave phenomenons of gas tail gateway at 3# seam are so severe during mining procedure that it has seriously effected the normal use of next working face and made the digging link strained in Hexi Coal Mine of Fenxi mining industry. The pa-per analyses the factor of big amount of floor heave of gas tail gateway, floor heave mechanism based on the actual project of gas tail gateway of 3# seam, choose appropriate measures for floor heave control by numerically studied means of FLAC3D software. The re-sult of practical experimentation indicates that the problem of floor heave in gas tail gateway having been basically solved. |
