... the capability to obtain accurate, fully geo-referenced three-dimensional datasets that can be subsequently interrogated to provide engineering-based solutions for monitoring of deformation processes, rock mass characterization and additional insight into any underlying failure mechanisms. Importantly, data can...

... mining conditions. The computations showed that the parameters of importance are well within the limit for permissible subsidence. The monitoring is done on a continuous basis at quarterly intervals, at two sites above the mine workings at Balaghat Mine. The quarterly monitoring data from Jan 2014 to Dec...

... Abstract Monitoring of pillar and roadway deformations is one of the most important issues in geotechnical engineering and mining practice. The use of 3D laser technology is ideal to monitor strata displacements in underground excavations enabling complex spatial data capture of the entire...

... mining and geological conditions. The measurement results showed that the most informative parameter for pillar stability estimation is its transversal strain. A new system based on a magnetostrictive sensor, recorder and transmitter to realize continuous remote monitoring of pillars deformation...

... deformation processes, which can be relatively precisely observed and measured. In order to verify the stress state of the rock mass and changes in it induced by longwall mining, monitoring of changes in the rock mass stress in connection with the mine out of the longwall No. 371 202 was carried out...

... in coal mining in the world [1–5]. As there is no relevant experience of using this method in the Upper Silesian Coal Basin, an extensive monitoring system has been implemented to enable the mining trial to continue safely. The monitoring is focused on the load-bearing capacity of the coal pillars...

... and external waste rock. Due to the nature of the rock mass and the extreme environmental conditions, slope monitoring at Siilinjärvi poses some challenges. Real-time critical slope monitoring at Siilinjärvi is performed by employing two IBIS Synthetic Aperture Interferometric Radars. The IBIS units are used...

... ABSTRACT: The authors performed ground motion measurements during blasting operations at several tunnels in association of rehabilitating the intercity roadways in Turkey in Zonguldak. The authors have been monitoring the blasting-induced vibrations in adjacent tunnel near at Üzülmez tunnel...

... problems that limit application of the laser scanner technology in unfavorable conditions including the explosion risk atmosphere, dust, humidity and instability of mine excavations. This technology has been currently used to monitor the coal mine roadway and pillar stability in the firstly developed room...

... ABSTRACT: Passive seismic monitoring data acquired at the potentially unstable granitic cliff of Madonna del Sasso (NW Italy) are presented in this work. The spectral content of seismic noise systematically highlighted clear energy peaks on the unstable sector, interpreted as resonant...

... ABSTRACT: Usage of Terrestrial Laser Scanners (TLS) is currently the best way of monitoring and detecting changes in slope morphology. In this study Optech ILRIS-3D was used. First scan of slope morphology with ILRIS-3D was made in March 2012 at presented pilot location "Znjan...

... ABSTRACT: The authors have attempted to monitor the dynamic response of the surrounding rock mass at the excavation face of Tarutoge tunnel at the prefectural border of Shizuoka and Yamanashi prefectures, Japan in relation to the connection route between New Tomei and Chuo Expressways...

... Kaunertal hydropower plant safety assessment monitoring construction surge tank ABSTRACT: The Kaunertal hydropower plant is in full operation since 1965 and is still one of the largest storage power plants in Austria. In 1962, tunneling for the pressure shaft and surge tank was found to be more...

... Abstract For the construction of the Untersberg cable car in 1961, the foundations of pillar 1 had to be tied back against the steep rock flank of the East face of the mountain with nine prestressed anchors. Since then, regular monitoring and two lift off tests have been carried out in order...

... Abstract On October 5 th , 2010, cracks were found in a gallery 1.80 m high and 1.40 m wide. The gallery is 100 years old and runs parallel to a valley flank. After eliminating several possible causes of cracking, a landslide producing the damages had to be taken into consideration. Monitoring...

... road. To monitor the slope displacements during construction of the site facility area a comprehensive monitoring program including various monitoring methods was implemented. According to the results of the numerical calculations, the expected target behavior and warning levels were defined...

... numerical modelling methods, used as means to back-analyze the reactivated landslide and the interaction with the tunnels, are discussed. It is shown how modelling associated with advanced real-time monitoring may contribute to the understanding of the problems under study. 1 Introduction During...

... Abstract Monitoring an underground radioactive waste repository is a key issue in order to ensure the long-term safety of such a project. It relies on very specific structures. A continuous monitoring of structural health implies not only numerous sensors but also a dedicated data processing...
