针对自然崩落法向无底柱分段崩落法过渡时底柱破坏的具体要求 ,为保证安全生产 ,提出了悬臂模型 ,并利用弹性力学的方法对底柱的受力情况进行分析计算 ,得出了悬臂折断时的长度。分析结果与现场实施情况基本一致
In order to meet the specific requirements of the failure of the bottom pillars during the transition from the pillarless caving method to the pillarless caving method, a cantilever model is proposed to ensure the safe production. The force of the pillar pillars is analyzed and calculated by the method of elasticity. The length of the cantilever when broken. Analysis results and the implementation of the scene is basically the same
