坑透高精度CT层析成像测量方法试验研究

Experimental study on a Working Method of Radio Penetration High Accuracy CT

随着开采深度的增加,井田内地质构造条件越来越复杂,在综采工作面内必须采取适当的物探手段进行探测,而无线电磁波坑透技术在探测地质构造方面有较为成熟的技术手段和准确度。该文通过对比三种不同数据采集方法,利用自行研制的软件进行处理,分析CT层析成像图与实际揭露断层的对应情况。结果表明,当发射角覆盖范围越大,接收数据为21个时完成的探测效果较好。

As increasing of the mining depth, the geological structure conditions is more complicated in the coal mine, these structures must be find out for fully mechanized mining face by geophysical exploration methods, and radio penetration method is mature and exact in detecting geological structures. Three data gathering methods were compared, the data was prosessed by the self - manufactured software, and the CT image was compared with the condi- tions of the disclosed faults. The results show that it is accurate when the transmission angle is more wide and the number of received data is 21.
