摘要
以陕北某煤矿大型工作面槽波地震工程为例,开展了超大型工作面内断层的槽波地震探测技术研究。槽波探测采用全排列接收,最大限度地保障了槽波信息的获得。根据得到的槽波记录数据以及CT成像结果,解释了工作面内断层的发育情况,与后期巷道揭露情况基本吻合。槽波地震勘探在大型工作面的成功应用,可为矿井实现盘区勘探提供技术支持。
ISS has been developed for years. However, the application of ISS has never came to the truth in supper coal face. This paper studied the application of ISS in one supper coal face in northern Shaanxi. The geologic con-dition of ISS is very well for getting interesting records. For finding out the layout of the faults already exposed in roadway, all patches were set on for mostly receiving the channel waves. By analyzing the records of ISS and the CT image we got, the layout of the interest faults has been explained, which coincides basically with the actual situation later exposed in roadway. The explanation of the faults provides important information for the coal face production. The successful application of ISS in supper coal face provides technical support for exploration in panel.
