【摘要】 遥感—岩石力学的试验研究表明,岩石在受力与灾变过程中存在特征性的红外辐射变化,利用红外手段可以监测岩石应力与灾变问题。在过去遥感—岩石力学试验研究的基础上,针对矿山与岩石破裂失稳有关的安全隐患问题,利用红外热像仪对河北省峪耳崖金矿和辽宁省齐大山铁矿进行了现场检测,结果表明,利用热像仪可以检测井下高矿压部位、冒落和片帮等危险性的部位、渗水部位以及露天矿中断层和滑坡危险区,这些区域在热像中呈现不同于周围正常岩石的温度色调。如果结合长时间动态观测,可以对这些矿山灾害进行预测预警。研究结果为矿山安全及防灾减灾提供了新的监测预警手段。更多还原

【Abstract】 The experimental research of remote sensing rock mechanics indicates that the infrared radiation of rock varied characteristically in the process of rock loading and catastrophe happening,and the infrared technology can detect the stress and catastrophe of rock.In this paper the infrared detection tests were carried out in Yu’ernie gold mine of Hebei province and Qidashan iron mine of Liaoning province on the basis of past experimental research to the issue of mine safety related to rock fracture and destabilization.The result showed that thermal imager could detect effectively the high-stress area of tunnel,roof caving,water seeping,fault and landslip of opencast mine.The thermal images in these area were different form that of normal rock around.If the detection is carried out dynamically for a long time,the thermal imaging technology can predict the happening of mine disaster.The test results provide a new method to detect and predict the disasters happening of mine.更多还原
