矿井冲击危险电磁辐射连续监测及预测研究

Electromagnetic radiation law of continuous monitoring and forecasting rock burst in coalmine

摘要: 煤岩电磁辐射监测技术可以预测、预报矿井冲击地压和煤与瓦斯突出等煤岩动力灾害。利用中国矿业大学自行研制和开发的KBD7煤岩电磁辐射连续监测系统及数据处理软件,在鹤岗矿业集团南山、峻德等有冲击危险的矿井成功地连续监测了煤矿煤岩电磁辐射。根据监测现场的实际情况,结合监测数据,分析了有冲击危险监测区域的电磁辐射连续监测规律,并提取了其中蕴含的冲击危险前兆信息,用于冲击地压的监测、预报。

Abstract: The electromagnetic radiation(EMR) technology can forecast coal or rock dynamic disaster,such as coal and gas outburst,rock burst etc.It is successfully coming true that continuously monitoring rock burst in Nanshan and Junde coalmine of Hegang Mining Group by using the KBD7 EMR monitoring system and correlative data-analyzing software which is developed by China University of Mining and Technology for oneself.According to the fact of monitoring field and the testing data,analyses the EMR rules of this field,summarizes the portentous information of rock burst which is implicated in the testing data,and uses to forecast the happen of rock burst.
