矿山对开挖空间支护设计要求的主要目标是：确保人员安全、确保设备安全、保持开挖空间正常发挥作用，并在达到上述目标的条件下优化系统的成本效果。在设计方面对达到上述目标的基本要求是：支护系统的承载构件必须保持对大的变形的抗力；必须限制支护跨度，避免支架问岩石冒
The main objectives of mine design requirements for excavation space support are to ensure the safety of personnel, ensure the safety of equipment and maintain the normal excavation space, and optimize the cost effectiveness of the system under the above conditions. The basic requirements for achieving these goals in design are: The load-bearing components of the support system must maintain resistance to large deformations; the span of support must be limited to avoid scaffolding
