分析SYT天然电磁波法探查铁新煤矿老空区的适用性,介绍SYT型物性探测仪的工作原理。通过对施工所采集的数据进行分析,查明铁新煤矿周边老空区的位置及范围,并通过水平截面地应力等值线图分析该老空区的赋水性,证明了SYT型物性探测仪探查老空区的准确性。 Analyze the applicability of SYT natural electromagnetic wave method to explore the old empty area in Tiexin Coal Mine and introduce the working principle of SYT physical property detector. Through the analysis of the data collected during the construction, the location and range of the old empty area around Tiexin Coal Mine were identified, and the water-bearing property of the old empty area was analyzed by the horizontal section stress-isogram map. It was proved that SYT-type physical detector Explore the accuracy of the old empty area.
