| 摘 要： | 为了分析工作面回采过程中各作业工序对电磁辐射测量的影响,在长沟峪煤矿回采工作面进行跟班测试,并对各回采工序的电磁辐射监测信号进行了定量分析。结果表明,绞车、刮板输送机、电铃等电气设备对电磁辐射测量的影响最大,是在线式电磁辐射监测的主要干扰源;支柱加压、人员走动等非涉电作业活动对电磁辐射测量的影响较小。研究结果为现场使用电磁辐射临界值法判别煤岩动力灾害危险时排除干扰源的影响提供了可靠依据。

| Abstract: | In order to analyze influence of each operation in mining process on measurement of electromagnetic radiation,a test was carried out on working face in Changgouyu Coal Mine and electromagnetic radiation monitoring signals of each operation were analyzed quantitatively.The results show that online electromagnetic radiation monitoring signals are mostly influenced by electrical equipments such as winch,scraper conveyor and bell which are main interference resources,and less interferenced by non-electric operation such as pillar compression and personnel moving.The research provides reliable basis for eliminating influence of interference sources while using electromagnetic radiation critical value method to judge coal-rock dynamic disaster at field. |
