摘要: 以山西省沁水煤田3#煤层为工程研究背景,运用大型仿真软件FLAC3D,深入系统地探讨了大断面煤巷开挖后的矿压显现规律,不仅掌握了大断面煤巷的矿压显现规律,而且在与小断面煤巷的对比研究过程中,揭示了大小断面煤巷矿压显现的差异性规律。
关键词: 大断面, 煤巷, 矿压显现, 数值模拟
Abstract: Taking the 3# coal seam in Qinshui coalfield as the research engineering background in this paper,the regularity of mine pressure of larege section roadway afer excavation is discussed by using the numerical simulation software of FLAC3D.The research results in this paper not noly contributes to mastering the mine pressure behavior regularity of lage section roadway,but also reveals the otherness rules of mine pressure of difference size section coal roadway in the process of comparison with small section.
Key words: Large section, Roadway, Mine pressure behavior, Numerical simulation
