| 摘 要： | 不明采空区对煤矿的安全生产构成潜在危害,而人工地震勘探对埋深较浅的采空区存在盲区。采用RAMAC/GPR探地雷达仪配备的超强地面耦合天线(RTA50MHz)探测采空区。由于煤层及采空区相对雷达探测的有效范围较深,综合考虑探地雷达的分辨率与探测深度的关系,选用合适的雷达参数和探测模式进行数据采集,并采用了VC++开发了三维系统进行了补充解释,实现了探测目标体的准确定位,取得较好的探测效果。 |
| 关 键 词： | 采空区 探地雷达 探测 分辨率 |

| Abstract: | Unknown gobs have always potential threats to work safety in coal mines, and there is a blind area when artificial seismic exploration is employed in gobs of coal mine of relatively shallow depth. To solve theses problems, this paper puts forward the basic theory and testing method of using the super ground coupled antenna (RTA50MHz) equipped with RAMAC/GPR to detect gobs of coal mines. Since coal seams and the gobs are too deep for ground penetrating radar to detect, the relationship between the resolution and the depth has to be considered. Proper parameters and modes of exploration have been employed to collect data. VC++ has been adopted and three-dimension has been developed for supplementary means of interpretation. Exact position of the target has been achieved and the exploration effect has been improved. |
