为了推进西部软岩大硐室围岩变形机理的研究，以鄂尔多斯地区红庆梁煤矿为背景，集中开展了室内岩石力学实验和数值模拟及现场监测研究，通过对数据的分析揭示了红庆梁煤矿大硐室开挖及施工期间围岩变形机理，提出了大硐室支护参数优化的建议。该研究成果为红庆梁矿后期建设的大硐室和巷道围岩控制提供了技术支持和借鉴。
In order to improve the study on the deformation mechanism of surrounding rock of underground chamber in soft rock area in the west of China, we carried out indoor rock mechanics experiment numerical simulation and field monitoring in Ordos Hong Qing Liang coal mine. Through the analysis of the data, we revealed that the large chamber excavation and deformation mechanism of surrounding rock during the construction. Some suggestions of the large chamber support parameter optimization have been given. The research results can provide technical support and reference for the cavern or roadway surrounding rock control in the later construction of the red Qing Liang mine.
