支护作为维护巷道安全的一个重要环节,必须进行不断的优化设计。讨论支护的受力变形和破坏状态,采用现场监测和数值模拟的方法进行研究,探讨最理想的支护情况,从而保证煤矿的安全运营、提高经济效益。
As an important part of maintaining roadway safety, support must be continuously optimized. The force deformation and failure state of the support are discussed. The on-site monitoring and numerical simulation are used to study the optimal support condition so as to ensure the safe operation of the coal mine and improve the economic benefits.
