北皂煤矿采区地震探采对比与效果分析
|
摘要
简述了龙口矿务局北皂矿四采区的工区地质特征及地震技术难点，介绍了该区开展采区高分辨率地震补勘所采用的“三小”、“三高”、“两保持”工作方法。该采区地震共查明断层35条，其中基本一致断层6条、新发现断层20条。修正断层9条。井巷工程历经两年多验证，发现断层中有6条。修正断层中1条被证实吻合非常好，仅有2条相距很近的组断层误判为一条断层；采区地震成果否定了一个综采面、解放了一个综采面、指出了两个地质条件简单工作面。至今己有四个面完成回采、一个综采大面系统形成，从而极大地缓解了工作面接续紧张状况。文中大量采探对比实际资料，提出了小断层地震极限分辨率的新认识，并指出高分辨率数字地震技术今后将在采区划分和工作面设计中发挥重要作用。该技术的推广应用具有极大的经济效益和社会效益。
The writers briefly introduce geological conditions and seismic technological difficulties of No. 4 miningarea, Beizao mine, Longkou Bureau, and the work methods of" three small", three high"," two preserve" in thesupplementary high resolution seismice exploration. 35 faults are finded out with seismic exploration of mining area,basic same is 6, new discovery is 20, corrected is 9. New discovery 6 faults and corrected 1 fault are proved throughmore than two years mine lane engineering, only the near two group faults is mistakenly judged one. The results ofseismic exploration deny one synthetic working face and save another, relax the tension of working face replace. Thenew viewpoint of limited seismic resolution to smaller faults is proposed, on the base of a great number of real exploration and mining contrast datas, and point out that high resolution digital seismic technoing will be more important in dividing the thening area and designing working face, in this article. Pushing out this technology have agreat econmic and social benefits.
