为在地面模拟煤层工作面坑透探测,利用地面建筑物作为探测目标体,采用矿井工作面坑透探测的工作方法布置观测系统进行探测实验.结果表明:(1)穿过地面建筑物路径的电磁波场强值显著降低,建筑物的高低及结构不同,对电磁波信号影响程度不同;(2)建筑物范围在场强平面图上表现为较低的场强值,在电磁波吸收系数平面图上表现为较高的电磁波吸收系数值;(3)建筑物适用于作为探测目标体进行地面坑透实验.%In order to simulate coal face radiowave gallery penetration prospecting on ground surface, taking surface buildings as the tar-get, in accordance with mine working face radiowave gallery penetration working mode laid out field setup and carried out prospecting experiment. The result has shown that:(1) the field intensity values of electromagnetic wave pass through buildings have significant re-duction, buildings with different heights and structures have different impacting degrees on electromagnetic wave signal;( 2) on the field intensity plan, within the range of buildings shown lower field intensity values, on the electromagnetic wave adsorption coefficient plan shown higher adsorption coefficient values;(3) buildings are suitable to use as prospecting target to carry out ground surface radiowave gallery penetration experiment.
