According to the detection of the unknown 13102 and 13103 area goaf in a coal mine in Ordos,the range of this area goaf was obtained by using the 428 seismograph and the artificial hypocenter with the manual hammer multiple stack. Based on the results of Surface drilling,the distribution of this area goaf was achieved, which would provide a basis for mine working face layout and safety science and security.%针对矿井老空区范围不明问题,使用428地震仪,采用人工锤击多次叠加为震源,对鄂尔多斯某矿13102和13103工作面内老空区分布进行地表探测,获得该区域老空区分布范围.并在地表打钻进行验证,准确掌握了该区域老空区分布,为矿井工作面科学布置及安全生产提供依据和保障.
