摘　　要：东胜煤田呼吉尔特矿区煤层厚度大、埋深大,煤层开采导水裂隙带存在超高发育现象。为研究呼吉尔特矿区某深埋矿井煤层开采覆岩裂隙的动态演化规律,采用相似材料模拟试验,模拟过程中采用VIC-3D技术监测采动裂隙的动态发育规律。相似材料模拟显示,导水裂隙带发育高度为88 cm,裂采比为30.8,裂隙带形态呈对称“梯形”;VIC-3D监测结果表明,在裂隙发育处,拉张应变较集中,基于VIC-3D监测的导水裂隙带应变云图形态与裂隙带形态相似,与模拟试验结果相吻合,VIC-3D监测技术能够进一步验证实际开挖中裂隙发育情况。The coal seams in the Hujirt mining area of Dongsheng Coalfield are thick and deeply buried,and there is a phenomenon of ultra-high development of water conducted zone in coal seam mining.In order to study the dynamic evolution law of overlying rock fractures during coal seam mining in a deep buried mine in the Hujirt mining area,similar material simulation experiments were conducted,and VIC-3D technology was used to monitor the dynamic development law of mining fractures during the simulation process.The simulation of similar materials showed that the development height of water conducted zone was 88 cm,and the fracture mining ratio was 30.8.and the fracture zone morphology was symmetric"trapezoidal",VIC-3D monitoring results showed that the tensile strain was more concentrated at the fracture development site.The strain cloud map of the water conducted zone based on VIC-3D monitoring was similar to the shape of the fracture zone,which was consistent with the simulation test results.VIC-3D monitoring technology can further verify the development of fractures in actual excavation.
