支架支撑点的最优选取策略研究

Research on Optimal Selection Strategy of Brace Point of Trestle

作为矿业生产的安全保障,支架的作用一直被高度重视。影响支架效能的因素很多,比如结构材质的强度和韧度及支架本身的结构特点等。此外,支架支撑点的不同也对安全防护效果有很大影响。在详细分析安全防护效果随支撑点变化规律的基础上,总结出支撑点的最优选取策略。该策略可为采用相同材质及结构的支架发挥最大安全防护效能提供参考依据。

As the security of mining production, the effect of trestle has been highly valued. There are many factors which can influence the trestle efficiency, such as the strength and toughness of structure material, as well as the structure characteristics of itself and so on. But beyond that, the different support points also have a great influence on the safety protection. Based on the detailed analysis of the law of safety protection changing with strong point, the optimal selection strategy of support point has been summarized. This selection strategy can provide a reference for the biggest safety protection performance of the trestle employed the same material and structure.
