中文摘要:
      花园煤矿床五采区岩浆岩较发育,严重影响该矿井的开拓设计,为了查明该矿井岩浆岩的分布特征,本文通过地震勘探预测方法的研究,利用该矿井三维地震数据进行了岩浆岩分布预测。基于钻孔和巷道揭露岩浆岩信息,建立等效地质模型,通过地震正演模拟岩浆岩的地震响应特征,从微观上认识岩浆岩在地震剖面上的反射特征;对于具有一定规模的岩浆岩,利用地震相分析和属性解释技术,对岩浆岩侵入范围进行宏观预测,取得了较好的效果,经验证与钻孔揭露基本一致。研究表明精确的岩浆岩预测范围对该矿安全高效开采具有重要的意义。
英文摘要:
      The magmatic rocks in the fifth mining area of Huayuan Coal mine are relatively developed, which seriously affects the development design of the mine. In order to find out the distribution characteristics of the magmatic rocks in the mine. In this paper, the distribution of magmatic rocks is predicted by using the 3D seismic data of the mine through the study of seismic exploration and prediction method. Based on the information of magmatic rocks exposed by boreholes and roadways, the equivalent geological model is established to simulate the seismic response characteristics of magmatic rocks through seismic forward modeling, and the reflection characteristics of magmatic rocks on seismic profiles are understood from the microscopic perspective. For magmatic rocks with a certain scale, the seismic facies analysis and attribute interpretation techniques are used to predict the scope of magmatic rock intrusion, and good results are obtained. The research shows that the accurate prediction range of magmatic rocks is of great significance to the safe and efficient mining of the mine.
