摘　　要：煤层顶板突水是我国煤矿开采最普遍水害之一。针对其特殊性及地震预测的难点,本文提出基于影响煤层顶板富水性主控因素的地震预测方法。以宁东红柳煤矿为例,预测砂泥比、顶板岩性、褶曲(以向斜为主)、裂隙发育程度(断层、地层曲率、应力场)等4项主控因素。针对不同的主控因素,选用地质统计学反演、地震等时切片技术、地震属性分析、应力场模拟等技术分别进行预测分析。预测结果通过已知工作面涌水量进行线性回归,确定出各项地震预测成果的权重系数,进行综合评价,实现了宁东红柳煤矿煤层顶板富水的综合预测,取得了较好的效果。Coal seam roof water inrush is one of the most common and direct water hazards in coal mining in China. In view of its particularity and the difficulty of earthquake prediction, this article presents an integrated seismic prediction method which is based on the main factors affecting the water - bearing property of coal seam roof. Taking the Ningdong Hongliu Coal Mine for example, through the geological analysis, we can draw a con- clusion that the geologic factors of coal seam roof water - rich such as sand - mud ratio, roof lithology, fold （mainly synclinal） , fracture development （fault, formation curvature, stress field and so on four main control factors; as for different master factors, the geostatistical inversion, seismic time slicing technique, seismic at- tribute analysis, stress field simulation and other techniques were used to predict and analyze; through the linear regression of the known water inflow, the weight coefficients of the earthquake prediction results are determined and evaluated synthetically which is carried out to realize comprehensive forecast of water inrush from coal seam roof in Hongliu Coal Mine of Ningdong.
