矿井进入深部开采后，围岩发生大范围塑性变形，给巷道支护工作带来了很大的困难。针对这一问题，以某矿深部开采条件为背景，研究了开采对邻近巷道的影响规律。总结出了动压影响条件下巷道失稳原因，并对其影响范围进行分析，为动压影响条件下巷道的合理布置、支护设计等工作提供了依据。%Rock deformation in deep mining brought great difficulties to laneway maintenance. To solve this problem, we studied the impact of mining on the adjacent laneway. The instability under dynamic pressure scope was analyzed to provide reasonable arrangement and supporting design.
