Application of Electromagnetic Radiation Technology in Analyzing the Strata Behavior Regularity in Working Face of Coal Mine
Abstract：Based on the EMR data analysis of 3408 and 3305 mining workface of LiangBaoSi coal, the stress distribution and change rule of coal and rock in the mining area are obtained. Accordingly, the dangerous areas in mining workface are divided. The analysis shows that the electromagnetic radiation signals can accurately reflect the internal stress distribution of coal and further indicate the extension of pressure discharging area and stress concentration area. Aiming at the high stress dangerous area, the method of drilling cutting and EMR are applied to monitor the internal stress distribution of coal. The analysis of the monitoring results shows the two kinds of monitoring method has high consistency on reflecting the internal stress of coal. The electromagnetic radiation technology is advantageous in its wide coverage, continuity and non-contact. While the method of drilling bits is advantageous in its high precision.
