摘要
为了预测煤矿冲击地压的危险,利用控制图分析煤矿冲击地压电磁辐射数据和工作面煤体电磁辐射随时间的动态变化趋势及规律,并且根据数据点的落点区域分布及点的序列状态来预测未来发生冲击地压灾害的可能性。研究表明,当不少于6个连续数据点呈连续增长或降低趋势时或者电磁辐射数据点连续落在控制图中线下侧时,都可能在未来发生煤岩的剧烈破坏或能量释放。
In order to predict the mine pressure bumping dangers, the control map was applied to analyze the electromagnetic radiation data of the mine pressure bumping and the dynamic variation tendency and law of the coal mass electromagnetic radiation in the coal mining face with the time and to predict the possibility of the pressure bumping disaster occurred in the feature base on the placement area distribution of the data point and the series status. The research showed that when not less than 6 continued data points were continuously in increasing or in deceasing tendency or the electromagnetic radiation data points were continuously lower in the down side of the central line of the control map, serious failure or energy releasing would be occurred in the coal and rock.
