摘　　要：基于煤体裂隙特征及水力压裂破裂准则,对水力压裂裂缝起裂和扩展机理进行分析,并基于某矿煤层地质条件,对分段水力压裂增透技术在1306工作面应用进行模拟。通过理论分析和数值模拟,为分段水力压裂增透技术在煤矿进行工业试验提供技术参数。Based on the fracture characteristics of coal and the failure criterion of hydraulic fracturing, the mechanism of hydraulic fracturing cracks crack and extension is analyzed ,based on coal mine geological conditions of coal seam, the piecewise water pressure anti-reflection technology applied in 1306 working face is simulated. Through theoretical analysis and numerical simulation,hydraulic fracturing in anti-reflection technology provide technical parameters in coal industrial experiment.
