枣泉煤矿大断面煤巷耦合支护数值模拟研究

摘要

为了寻求枣泉煤矿12205胶带巷合理的支护方案，应用数值软件FLAC3D对不同的支护方案进行模拟。通过对各支护方案模拟结果的分析，得出了该种地质条件下应该采用锚梁网索耦合支护形式，对具体的工程实践提供了一定的理论依据。%In order to reveal the reasonable support scheme for 12205 Haulage Gate in Zaoquan Coal Mine numeri- cal simulation software named FLAC3D was adopted in different supporting project in this paper. According to the analysis of the simulation result of different supporting project, the paper draws the conclusion of bolt - net - anchor coupling support under such a geologic condition. This analysis provides a theory basis for the specific project.
