摘要:
确定导水裂隙带高度是水下开采防水煤岩柱尺寸设计的关键。结合导水裂隙带形成机理和分布形态，选取采场采深、采厚、煤层倾角、覆岩单轴抗压强度和工作面斜长五个主要影响因素作为导水裂隙带高度的判别指标。利用24组样本数据，构建导水裂隙带高度的熵权属性测度预测模型。为检验模型的有效性，将其用于预测丁集煤矿1262(1)工作面导水裂隙带高度，结果为6603m，与采用Midas/GTS-Flac3D耦合模拟得出6463m的结论非常接近。研究结果表明，熵权属性测度模型预测的相对误差较小，可以在工程实际中推广应用。
Abstract:
Determining the height of water flowing fractured zone is the key to design the size of waterproof coal pillar in underwater mining. Firstly, combined with the formation mechanism and distribution pattern of water flowing fractured zone, five major factors including the mining depth, the minable thickness, the coal dip angle, the uniaxial compressive strength of overlying strata and the oblique length of working face were regarded as the discriminant factors for predicting the height of water flowing fractured zone. Afterwards, the model of entropy weight attribute measure theory for predicting the height was established based on 24 groups of sample data. To test the reliability, the model was used to predict the height of water flowing fractured zone in working face 1262(1) of Dingji Mine. The result was 66.03 m, which was similar to the simulated value 64.63 m by Midas/GTS-Flac3D coupling simulation. In conclusion, the relative error of prediction by entropy weight attribute measure model is smaller, and it can be applied in the actual engineering.
