摘　　要：为了分析红一煤矿4煤层岩体应力空间分布特征及其与矿压显现的关系,利用地质动力区划方法对井田范围内的活动断裂进行识别和划分,以所划分的活动断块为构架,通过岩体应力状态分析系统计算确定了井田岩体应力状态,划定了不同的4个应力分区,并且明确了不同应力分区的微震及对矿压显现的影响。根据现场采集的各类矿压监测数据,与岩体应力分析结果进行对比分析,确定了矿压显现与岩体应力的耦合关系,确定井田矿压显现主要受到由活动断裂产生的高应力控制。研究结果可为红一煤矿矿压显现预测及其控制提供指导。In order to analyze the spatial distribution characteristics of rock mass stress and its relationship with the rock pressure manifestation in No.4 coal seam of Hongyi coal mine,the geological dynamic zoning method is used to identify and divide the active faults in the mine field.Based on the divided active fault blocks,the stress state of the rock mass in the mine field is determined through the calculation of the rock mass stress state analysis system,and the high stress area,low stress area and high stress gradient area are defined.Based on the observation data of rock pressure,the relationship between the rock pressure behavior and the stress state of rock mass is analyzed,and it is determined that the rock pressure behavior in the mine field is mainly controlled by the high stress generated by the active fault.The research results can provide guidance for the prediction and control of rock pressure behavior in Hongyi coal mine.
