In this paper, the authers brief the development history of mine detection technology,and introduce in detail some new detection technologies,such as pulse radar, neutron detection,infrared ray,NQR as well as comprehensive detection technology. (by Zhou Lijun et al)
For complicated associated many mined-out areas, composite detecting technology with generating ground radar(GPR) and Raleigh wave method is taken forward, on the base of on-the-spot photography investigation.
For complicated associated group mined-out areas exist at Changba Lead-zinc Mine,composite detecting technology with generating ground radar and Raleigh wave method is taken forward.
Engineering geology condition was detected by comprehensive exploration technology of geophysics,and the seepage tunnel was departed along its length according to probably appearing engineering geology problems.
This study shows that the available reasonable and effective technologies can detect and predict geological disasters,which will play a important role in tunnel constructions.
:Karst collapse pillars are one of serious geological disasters in coal mining in China. In order to determine the possible bounds of karst collapse pillars, the mulit-factor overlap analysed of airborne remote sensing information as well as geology and mining data with the help of PC ARC/INFO GIS have been proposed. Based on the analysis result, the comprehensive geophysical explora tion can be used for verifying the karst collapse pillars. The experiments in a coal mine show that the new^ compreh...
The author of this paper analyses the features of delecting hidden troubles of dams and river banks us- ing the method of geophysical prospecting and uses the technique of integrated detection to increase the veracity and reliability for river banks detection. Some examples about the technique's application are given in the article including the dams or banks of Beidagang reservoir, the Yongdingxinhe River,the Duliujianhe River and Jiyunhe River.
