摘要
提出了一种煤矿开采二维物理相似模拟试验平台。该平台具有可模拟煤矿开采1000 m埋深以内的地应力、可调角度、可做垂向及两侧地应力模拟加载、可模拟煤层开采等功能,并经有限元分析验证了其强度和刚度。该平台可以为煤矿开采的安全和高效提供重要的技术支撑。
A two-dimensional physical similarity simulation test platform for coal mining has been proposed.This platform has functions such as simulating ground stress within a burial depth of 1000 m in coal mining,adjustable angle,vertical and lateral ground stress simulation loading,and simulating coal mining.Its strength and stiffness have been verified through finite element analysis.This platform can provide important technical support for the safety and efficiency of coal mining.
