| 摘 要： | 巷道受重复采动影响,围岩状况发生恶化,巷道围岩变形是一个动态的拉压交替的过程。为解决下覆煤层组开采过程中巷道围岩稳定性问题,分析了下覆岩活动规律和大巷围岩稳定性特征。基于动态控制过程原则,确定合理的加固技术与加固原则,并对加固后的大巷围岩的稳定性进行合理预测。泉沟煤矿-115大巷的相似材料模拟实验和现场工程实践表明,该技术可行,可以在类似条件的巷道中推广应用。

| Abstract: | Entry is influenced by repeat mining,the worsening surrounding rock and the entry surrounding rock deformation occurring as a dynamic phases which is tensiled firstly and then be pressed.The efforts to solve the stability of underlie coal seams by analyzing the law governing the underlie coal seams mined and the character of surrouding rock deformation of entry,based on the principle of dynamic control process and three key aspects: analyzing the strata movement regularities resulting from the two underlie ... |
