煤矿井下探地雷达应用试验研究

Study on Applied Test of Ground Penetrating Radar(GPR)in Underground Mine

国家重大科学仪器设备开发专项子课题研究中,对ZTR12系列探地雷达进行了改进,大大提高了对地质构造的探测效果,其性能指标基本满足煤矿井下探测需求。采用改进后的ZTR12系列探地雷达,进行煤矿井下探测试验。试验过程中,发现煤矿井下存在探测空间狭小、巷道侧壁探测环境复杂等问题,影响探测效果。针对上述问题,提出了改进措施,研究成果对提高煤矿井下地质构造探测效果具有一定的指导意义。

In a study on a special program of the national major science instrument equipment,the ZTR12 series ground penetrating radar was modified The detection effect of the geologic structure was highly improved and the performance index could basically meet the detection requirements in the underground mine The modified ZTR12 series ground penetrating radar was applied to the detection test in the underground coal mine During the test process,the narrow detection space,complicated detection environment of the roadway sidewall and other problems existed in the underground coal mine were affected to the detection effect According to the above problems,the improved measures were provided and the study achievements would have certain guide significances to improve the detection effect of the geological structure in the underground coal mine.
