含瓦斯煤岩固气耦合动态模型与数值模拟研究
The research on triaxial creep properties of coal containing gas is the important aspect of understanding the interactional relationship between gas and coal in the course of outburst.
研究含瓦斯煤岩的三维蠕变特性是理解煤与瓦斯突出孕育过程中瓦斯和煤岩相互作用关系的重要方面,而目前含瓦斯煤岩三维蠕变特性的研究很少,因此需要进一步深入研究含瓦斯煤岩的三维蠕变特性。
Based on the model test of simulated material, the failure action on seam floor coming from abutment pressure is analysed when top slice of thick gassy coal seam is mined.
通过相似材料模拟实验,分析了含瓦斯厚煤层顶分层开采时支承压力对煤层底板的破坏作用,并根据压力分布和破坏程度对煤层底板裂隙沿深度方向进行定性定量分带,计算出底板最大破坏深度及其位置,探讨了各分带瓦斯运移特征,进而阐述了顶分层开采对下分层的解放作用,为安全、合理开采含瓦斯厚煤层且有效抽排煤层瓦斯提供了理论依据。
