特厚煤层首采面冲击地压监测方案研究

A Study on the Surface Pressure Monitoring Scheme of the First Mining Surface of Extra-thick Coal Seam

针对具有冲击倾向性的特厚煤层首采工作面冲击地压危险,开展冲击地压监测技术研究。具体采用了微震法、应力在线监测法、钻屑法、矿压监测法等综合手段开展监测工作,提出了各监测手段的具体实施参数,对其他相似条件下特厚煤层首采面冲击地压监测工作具有指导意义。

By a study of the impact pressure of the first mining face of the extra-thick coal seam with the impact inclination, the paper put forward a scheme for monitoring the impact pressure., that is to combine the seismic method, on-line monitoring method, drilling cuttings, mine pressure monitoring,with other comprehensive measures to carry out the monitoring work, and the concrete implementation parameters of each monitoring method are also put forward. Which can play an important role in guiding the impact ground pressure monitoring work in other similar extra-thick coal seams.
