摘要
根据汾源煤业的地质及开采条件,通过损伤理论分析和现场监测的研究手段,分析了大倾角煤层煤体损伤、支承压力和支架阻力的变化规律,现场观测确定了来压参数和特征,根据煤体应力监测和支架载荷监测结果,提出了开采建议,为类似条件的煤层开采提供借鉴。
According to the geology and mining conditions of Fenyuan Coal Industry Co.,Ltd.,the paper analyzes the change law of coal body damage,support pressure and support resistance of large-inclined-angle coal seam through the damage theoretical analysis,determines the weighting parameters and characteristics through on-site monitoring,and proposes the mining suggestions according to the monitoring results of coal body stress and support load,providing a basis for the coal seam mining under similar conditions.
