摘要:

近年来,新兴矿已进入深部开采,冲击灾害显著增加且越来越严重,冲击矿压事故频繁出现,已严重影响矿井的安全生产。本文利用电磁辐射技术对61051、41062工作面冲击矿压进行监测,分析冲击矿压危险的电磁辐射变化规律,利用模糊模式识别方法确定冲击矿压电磁辐射预测临界值,实现对薄硬煤层开采过程中的冲击矿压监测、预测。通过现场的监测基本掌握了冲击前兆及高危区域的电磁响应规律;圈定出危险重点监测区域并多次成功对冲击发生作出预警。

Abstract:

As the coal mining depth and strength increase, rock-burst hazards has become increasingly serious. In recent years, rock-burst accidents happen frequently in the new mines, influence the safety production seriously. In the past two years, the mine has clearly entered deep mining, rock-burst hazards increased significantly and more and more serious. The paper monitors rock burst of 61051、41062 working face by electromagnetism radio technology, analyses the regular of electromagnetism radio, confirm forecasting critical value of electromagnetism radio by indistinct recognition method, knows rock burst premonition and electromagnetism radio of hazardous region, and forecasts rock burst time after time in hazardous region.

Key words: rock burst, thin coal seam, electromagnetism radio technology, regional prediction
