摘　　要：淮南矿区A组煤的安全高效开采是保证华东地区能源供应的重要前提,准确掌握地下煤层的构造形态、发育情况是安全生产和减少事故发生的必要条件。以张集矿1613A工作面为工程背景,采用被动成像和噪声成像技术,对工作面顶底板的微地震监测资料进行分析,工作面已注浆治理的断层破碎带附近微地震事件较多,最深达到工作面下方约80 m的位置,有效验证了该断层破碎带的存在。通过反演的方法分析检波器中接收到的波形信号,获取工作面附近的波速场信息;利用西二、西三_(1)煤采区三维偏移数据体,计算了多种属性,研究了已揭示地质异常体的地震响应特征和属性特征,发现本区构造与地质异常体的研究需要特别注意蚂蚁体、最大曲率、最小曲率、局部异常、落差5个属性的指示作用。研究表明,以三维偏移数据体为基础,提取的各个属性对大断层均有显示,能够进行有效解释;对落差较小断层显示较好的属性是蚂蚁体属性和最大曲率、最小曲率、局部异常、落差属性。Safe and efficient mining of Group A Coal in Huainan mining area is an important prerequisite to ensure energy supply in East China.Accurate understanding of the structural form and development of underground coal seams is a necessary condition for safe production and accident reduction.This article took the No.1613A working face of Zhangji Coal Mine as the engineering background and used passive imaging and noise imaging techniques to analyze the microseismic monitoring data of the roof and floor of the working face.There are many microseismic events near the fault fracture zone that has been grouted and treated in the working face,with the deepest reaching about 80 m below the working face,effectively verifying the existence of the fault fracture zone.Analyze the waveform signal received in the detector through inversion method to obtain information about the wave velocity field near the working surface.Using the 3D migration data volume of the WestⅡand WestⅢ_(1) coal mining areas,various attributes were calculated and the seismic response characteristics and attribute characteristics of the revealed geological anomaly bodies were studied.It was found that the study of the structure and geological anomaly bodies in this area requires special attention to the indicative role of five attributes:ant body,maximum curvature,minimum curvature,local anomaly,and drop.Research showed that based on the 3D migration data volume,all extracted attributes were displayed on large faults and can be effectively interpreted.The attributes that display better for faults with smaller drops were ant body attributes and maximum curvature,minimum curvature,local anomalies,and drop attributes.
