| 摘 要： | 砂(砾)岩等碎屑岩类含水层广泛发育于含煤地层中，矿井建设及煤炭资源开采过程中引发的突水事故严重威胁了煤矿安全生产，碎屑岩类含水层富水性评价成为矿井水害防治工作的重要工作。本文选取岩层结构与地质构造2个指标作为碎屑岩类含水层富水性的控制因素，提出岩性结构系数量化含煤地层岩性及其组合关系，引入分形理论定量评价地质构造复杂程度，基于此构建含水层富水性评价模型，依据矿井已有工作面突水资料，确定含水层富水性分区阈值及其等级划分标准，形成了碎屑岩类含水层富水性预测方法。研究成果成功应用于高庄煤矿湖下3上1煤层顶板砂岩含水层富水性评价工作中，取得良好效果。

| Abstract: | Clastic aquifers such as sandy (conglomerate) rock are widely developed in coal-bearing strata. Water inrush accidents caused by mine construction and coal resources mining seriously threaten the safety of coal mine production. Water-rich evaluation of clastic rock aquifers have become an important part of mine water hazard prevention and control. Two indexes of rock structure and geological structure are selected as the controlling factors of water-rich of clastic rock aquifers. Lithological structure coefficient is proposed to quantify the lithology and its combination relationship of coal-bearing strata, and fractal theory is introduced to quantitatively evaluate the complexity of geological structures. Based on this, an aquifer water-rich evaluation model is established. According to the data of water inrush from the existing working face in the mine, the threshold of aquifer water-rich zoning and its grading criteria are determined, a prediction method for water-rich of clastic rock aquifers has been formed. The research results have been successfully applied to water-rich prediction of roof sandstone aquifer in No.3-1 coal under Huxia in Gaozhuang Coal Mine, and good effects have been achieved. |
