摘要: 基于综放采场支架围岩关系,建立了综放采场来压阶段支架载荷计算模型,引入三铰拱平衡原理推导出来压阶段支架冲击载荷的计算公式.以山东某矿1306综放工作面为例,应用上述模型和公式,得到来压阶段支架冲击载荷为7.19MN,支架载荷为13.3MN,与实测结果13.11MN基本一致,验证了计算模型的有效性,从而为综放采场来压阶段支架载荷计算和支架选型提供了理论依据.

Abstract: Based on the relationship between the support and the surrounding-rock in a fully-mechanized sublevel caving face, a model for calculating the support load during cyclic weighting is built, and the formula for calculating impact load on the support during cyclic weighting is obtained based on the principle of the three-hinged arch balance. The model and the formula are applied to the no.1306 working face, and it is shown that the impact load on the support during cyclic weighting is 7190 kN, and the support load during cyclic weighting is 13300 kN. According to the measured results, the support load during cyclic weighting is 13110 kN. The effectiveness of the model for calculating the support load during cyclic weighting in the fully-mechanized sublevel caving face is thus verified. The method can be used for the support selection and the support load calculation during cyclic weighting in the fully-mechanized sublevel caving face.
