摘　　要：在分析良庄井田地质资料的基础上,采用I值最大判别原则,最终确定奥灰水压及15~#煤层断裂构造复杂程度是影响底板突水危险性划分的重要因素。根据良庄井田地质资料,获得了奥灰水压等值线图、15~#煤层断裂构造复杂程度图、15~#煤层底板突水系数等值线图,采用信息融合的方法,获得了15~#煤层底板突水危险性分区图,与已开采煤层的实际情况相符。Based on the analysis of geological data of Liangzhuang coal field, the maximum I value discrimination principle was used to determine the Ordovieian limestone water pressure and the complexity of No. 15 coal seam fault structure, which was an important factor affecting the water inrush risk division of the floor. According to the geological data, the Ordovician limestone water pressure isoline map, the No. 15 coal seam fracture structure complexity diagram and the No. 15 coal seam floor water in- rush coefficient contour map were obtained. By using the method of information fusion, the risk zoning map of water inrush from No. 15 coal seam floor was carried out, which was consistent with the actual situation of mined coal seam.
