本文设计开发了一种新型非接触式煤与瓦斯突出预测仪,利用天线接收含瓦斯煤断裂破坏过程中产生的电磁辐射,以事件记录方式检测高于给定阈值的电磁幅射事件发生时间及所属频段,可间接反映出采掘工作面前方煤层受力破坏情况,实现了煤与瓦斯突出危险性的非接触预测.
In this paper, a new type of non-contact coal and gas outburst forecasting instrument is designed and developed. The antenna is used to receive the electromagnetic radiation generated during the rupture of gas coal, and the event recording method is used to detect the occurrence time of electromagnetic radiation incident above a given threshold. Its frequency band can directly reflect the stress and damage of the coal seam in front of the mining work face and realize the non-contact prediction of the danger of coal and gas outburst.
