摘要
地下隐伏采空区的存在严重威胁着生产和人员的安全,运用科学合理的手段进行空区探测,是保障矿山安全的重要措施。本文利用地震映像法,对鞍山地区某大型露天铁矿进行隐伏采空区探测技术方法的研究,并经工程钻探验证,取得良好的效果。通过对探测结果的分析表明,同相轴错动、同相轴缺失、能量减弱、同相轴弯曲呈眼球状等异常特征可作为铁矿空区探测的解译标志。
Hidden goal threatens production and people＇s safety. The important measure of ensuring the mine safety is to use the scientific and reasonable method to detect goal. In this paper, the seismic imaging method is applied to studying the detection method of con- cealed gob at a large open--pit iron mine in Anshan--Benxi district; and the engineering drilling tests show that the effect is good. The analysis of the detection results suggests that some abnormal characteristics can be used as interpretation signs in iron mine gob de- tection such as the dislocation and lack of phase axis, the weakening of energy, and the phase axis bending as an eye ball.
