摘要
针对邵寨煤矿1502工作面顶板导水裂隙带发育特征展开研究。基于回归分析法建立侏罗系煤层开采导水裂隙带高度预测模型,并用FLAC3D数值模拟软件和钻孔双端封堵实测进行验证。结果表明,回归分析法导水裂隙带高度129.17 m,模拟高度为137 m,钻孔双端封堵实测高度131.4 m,导水裂隙带形态呈“扁平拱形”。研究结果为邵寨煤矿1502工作面的安全回采提供了科学数据,也为类似矿井顶板裂隙带高度的合理预测和安全生产提供了经验借鉴。
The development characteristics of roof water conduction fracture zone in No.1502 Face of Shaozhai Coal Mine were studied.Based on the regression analysis method,a prediction model for the height of water conduction fracture zone in Jurassic coal seam mining was established,and it was verified by FLAC3D numerical simulation software and drilling hole double-end plugging measurement.The results showed that the height of the water conduction fracture zone by regression analysis was 129.17 m,the simulated height was 137 m,the measured height of the double-end plugging of the drilling hole was 131.4 m,and the shape of the water conduction fracture zone was'flat arch'.The research results provided scientific data for the safe mining of No.1502 Face in Shaozhai Coal Mine,and also provided experience for the reasonable prediction and safe production of roof fracture zone height in similar mines.
