槽波透射法探测煤层中夹矸分布区试验

Coal gangue area exploration test using the in-seam wave transmission method

文中在工作面槽波透射法探测原理的基础上,研究含夹矸条件下的槽波数据频散特征、槽波的数据采集与数据处理方法,并以阳泉集团开元公司9713工作面为例开展槽波探测试验。通过试验预测了工作面内夹矸的分布范围,划分煤层分叉边界。预测结果与巷道揭露一致。

In this paper,on the basis of the detection principle of in-seam wave transmission method on working face,the dispersion characteristics of in-seam wave data,the data acquisition and data processing method of in-seam wave were carried.Taking the working face 9713 of Kaiyuan Company of Yangquan Group as an example,the in-seam wave detection test was carried out.Distribution range of the gangue was predicted and the bifurcation boundary of the coal seam was divided in the working face.Predicted results were consistent with roadway exposure.
