基于参数优化试验的工作面空巷探测技术研究

Detection Technology of Working Face Abandoned Roadway Based on Optimal Parameters

煤矿老旧空巷引起的水害是国内资源整合矿区面对的重要灾害之一,为了查明朝阳煤矿9101工作面内部老旧巷道的分布范围及其富水情况,在巷道掘进过程中通过基于瞬变电磁法频率、叠加次数的参数优化试验,确定了工作面内部老旧巷道探测的最优化参数,指导9101工作面内部老旧巷道的探测工作。试验结果表明:工作面内部老旧空巷位置同探测结果存在显著的对应关系,经过频率、叠加次数参数优化处理的空巷探测技术可以有效确定空巷的分布及其富水情况,可为工作面的安全回采提供依据。

The water disaster that induced by abandoned roadway of coal mine was one of importantdisasters that must faced to for resources reassignment mine area in home, in order to ascertained the distribution scope of abandoned roadway and water distribution of 9101 working face of Chaoyang coal mine, on the basis of parameters optimal experiment of transient electromagnetic method and stacking fold during roadway driving process, the optimization parameters of abandoned roadway in working face, it references for defection working of abandoned roadway in working face. The results showed that an obviously corresponding relation was appeared between the abandoned roadway position and detection results. Detection technology of abandoned roadway was effectively after frequency and stacking fold optimized.
