摘要
以义马跃进煤矿具有强冲击倾向性的25110工作面为研究对象,通过分析工作面某段回采时期内支架工作阻力、能量频次、大能量事件以及电磁辐射等数据的变化规律,得到多个参量和顶板来压前后有很好的耦合关系的结论。采用多参量耦合对工作面顶板周期来压实现预测预报,从而提前采取安全措施来防治冲击危险的发生,为矿山的安全生产提出了一种新的思路。
Aimed at the tendency of strong impact at 25110 working face, the variation laws of working resistance of supporters, energy frequency, huge energy events and electromagnetic radiation were analyzed, and the multi-parameters were obtained, being of the coupling relation- ship before and after roof weighting. The multi-parameter coupling can be used to forecast and predict the periodic roof weighting, so that the safe measures can be made in advance to prevent and control the impacting risk, providing a new idea for the safe production of mines.
