透射槽波探测不规则工作面内小构造的应用

Application of Transmitted Channel Wave in Detecting Small Structures in Irregular Working Face

山西某煤矿属于我国华北型矿井之一,该矿工作面内陷落柱和断层较为发育,严重影响煤矿的安全生产及进度,有必要对工作面内的小构造进行探测。为该煤矿15104不规则工作面安全高效回采,以槽波形成机理及传播规律为基础,根据槽波能量的有无及强、弱,利用槽波透射法进行探测,并采用CT成像技术进行解释。实践表明,透射槽波勘探技术能够对不规则工作面内的小构造进行较准确预测,对矿井安全生产及提高经济效益具有重要意义。

The Coal mine in Shanxi belongs to the category of North China mines.The development of collapse columns and faults seriously affects the safe production and progress of coal mines.It is necessary to detect small structures in the working face.In order to ensure the safe and efficient mining of the 15104 irregular working face of a Coal Mine,Based on the in-same wave formation mechanism and its spread rule,According to existence、strength and weakness of same wave energy,the channel wave transmission method was adopted and CT imaging technique was used for interpretation.Results shown that the transmitted channel wave can accurately predict the small structures in the irregular working surface,which is great significance to safeguard the safe production of mines and boost economic benefits.
