摘要
基于A矿7604运输巷绕道由于受到各方面应力的作用而发生比较突出的片帮现象,并发生顶板下沉等问题,探讨了巷道的侧向与超前支承压力等,同时研究了科学合理的支护方案。通过具体的工程实践发现,选择这种加固方法后,7604运输巷绕道变形和破坏问题得到有效解决,使巷道能够长期处于稳定状态。
According to the prominent rib spalling phenomenon of the 7604 transport lane of A mine due to the effect of various stress and the roof subsidence phenomenon, this paper discussed the lateral and forward supporting pressure of the roadway and studied the scientific and reasonable support scheme. Through the concrete engineering practice, it was found that the deformation and failure of the 7604 lane could be effectively solved, ensuring the stable situation of the roadway after adopting this reinforcement method.
