| 摘 要： | 煤层顶板的富水性与顶板的岩性、孔隙及断裂构造的发育强度有关，其中岩性和孔隙的分布具有空间连续性，而断裂构造在空间上发育不连续，决定着煤层顶板的富水性具有空间性和非线性。本文结合潘谢矿区地质构造的特点，并以谢桥矿为例，选取了断裂强度、断裂密度、砂岩厚度、砂质泥岩厚度和泥岩厚度做为评价指标，利用MapObjects的空间分析功能和非线性人工神经网络（ANN）技术，对该矿6煤层顶板的富水性进行了评价分析。

| Abstract: | The water yield property of coal roof in relation with nature of roof rock strata, Pore and development intensity of faulted structure,including the distribution of lithology and pore space with continuity, and faulted structure and development in spaee is not continuous, determine the water yield property of coal roof have spatiality and nonlinear. In this paper, mining Panxie characteristics of geological structure and mineral Xieqiao example, select fracture strength,fracture density,the thickness of sandstone, sand-mudstone and mudstone as the thickness of evaluation,the use of MapObjects spatial analysis functions and nonlinear artificial neural network （ANN） technology, the water yield property of 6 coal roof analysis was evaluated . |
