介绍了煤巷掘进中影响天然电磁辐射场测量的各种干扰信号源。并在白皎煤矿考察了煤电钻、风钻、装岩机、电缆等机电设备工作所产生的电磁波(包括高次谐波)对天然电磁辐射场的影响程度。同时根据不同干排扰源的特征和天然电磁场的特点及分布规律,提出了处理措施,为天然电磁辐射预测突出技术的推广应用奠定了基础。
This paper introduces various interference signal sources that influence the measurement of natural electromagnetic radiation field in coal tunneling. And explored the influence of electromagnetic waves (including higher harmonics) generated by the work of electromechanical equipment such as coal-electric drill, air drill, rock loader, cable and other mechanical and electrical equipment on the extent of natural electromagnetic radiation field in Bajiao Coal Mine. At the same time, according to the characteristics of different sources of dry noise and the characteristics and distribution of natural electromagnetic fields, the treatment measures are put forward, which lays the foundation for popularization and application of the prominent electromagnetic radiation forecasting technologies.
