探地雷达用于采煤区地表拉张裂隙探测研究

Study on Detection of Surface Tension Fracture in Coal Mining Area Based on Ground Penetrating Radar Technology

采煤区地表拉张裂隙发育特征的精准探测对于开展矿区地质环境整治具有重要意义。利用探地雷达技术开展了采煤区地表拉张裂隙发育位置、深度的探测,并与坑探实测及拟合分析结果进行对比,研究结果表明:探地雷达可以探测拉张裂隙发育位置、深度;探地雷达探测结果与坑探实测及拟合分析结果具有较高的吻合度,表明探地雷达技术在采煤区地表拉张裂隙发育特征探测方面具有较好的应用效果。

The accurate detection of the development characteristics of surface tension fractures in coal mining area is of great significance for the improvement of geological environment in mining area. In this paper, the development position and depth of surface tension fractures in coal mining area was detected by GPR technology, and compared with the measured results and fitting analysis results of pit exploration. The results show that GPR can detect the development position and depth of tension fractures;The GPR detection results are in good agreement with the pit survey and fitting analysis results, which shows that the GPR technology has a good application effect in the detection of the development characteristics of surface tension fractures in coal mining area.
