强干扰条件下矿井电梯井井壁损伤精细探测

Fine Detection of Mine Elevator Shaft Wall Damage under the Condition of Strong Interference

摘要: 为了准确有效地探测矿井电梯井井壁损伤情况，为下一步采取安全措施提供技术支撑，以北洺河铁矿电梯井井筒为例，阐述了地质雷达在矿井井壁损伤探测中的应用。利用高频电磁波的反射，准确的探测出井壁破碎情况，经过对探测数据的处理，发现目前该井壁主要存在21处隐患，其中10处井壁破损情况较严重，集中在0.4~1.2 m深度范围内；井壁浅部附近空鼓和张裂情况有18处，主要集中在0.3~0.7 m深度范围内，本次探测结果为下一步的防治工作提供了一定的依据。结合探测结果综合分析表明：地质雷达在矿井井筒损伤探测与治理中作用巨大，能够为矿井的安全生产提供技术保障。

Abstract: In order to accurately and effectively detect the mine elevator shaft wall damage and provide technical support for taking safety measures in the next step, taking Beiminghe Iron mine elevator shaft as an example, this paper expounds the application of geological radar in mine shaft wall damage detection. Using the reflection of high-frequency electromagnetic wave, we can accurately detect the broken situation of the shaft lining. After processing the detection data, we find that there are 21 hidden dangers in the shaft lining, of which 10 are seriously damaged, concentrated in the depth range of 0.4~1.2 m; there are 18 hollowing and tension cracks near the shallow part of the shaft lining, mainly concentrated in the depth range of 0.3~0.7 m. The detection result is the next step. It provides a certain basis for the prevention and control of the disease. Combined with the detection results, the comprehensive analysis shows that geological radar plays an important role in the detection and treatment of mine shaft damage, which can provide technical support for the safety production of the mine.
