“…The GPS monitoring can achieve large-scale and real-time synchronous measurements of vertical and horizontal displacements accurately. Thus, GPS measurement has been used in the ground deformation study over mined areas (Mancini et al 2009a, b;Wang et al 2011;Liu et al 2012;Eray et al 2013;Zhou et al 2014). …”

Underground backfill mining is a complex and high-cost mining technique, which was designed to control ground pressure and prevent rock mass movement and ground deformation. Unfortunately, the results were not always as good as expected in practice. This paper addresses a case of ground movement induced by backfill mining in a nickel mine, China. Combined with geological investigation and ground monitoring, emphasis was put on the analysis of ground movement and interpretation of the deformation and damage. The results showed that a ground depression was formed at the hanging wall surface of the mine. By the end of 2013, the maximum subsidence reached 2,404 mm and accompanied by the rapid development of ground fissures. The monitored ground movement corresponded well with the underground goaf and the distribution of the ground fissures. It also found that the seriously deformed and damaged tunnels were exactly located in the plane projection of the subsidence trough. In addition, this study suggested that the high-level in situ stresses strengthened the mechanical strength of the surrounding rock mass and affected the overriding displacements in the wall rocks, thereby resulting in lower magnitude of vertical subsidence but greater expansion of horizontal deformation of the ground.

“…EMD is a signal processing method that can be used for nonlinear time series processing. This method is suitable for unmodeled system error handling [149,[155][156][157]. Taking the multipath effect as an example, it is still a challenge to develop a general multipath correction model for different GNSS stations [158].…”

In the past few decades, global navigation satellite system (GNSS) technology has been widely used in structural health monitoring (SHM), and the monitoring mode has evolved from long-term deformation monitoring to dynamic monitoring. This paper gives an overview of GNSS-based dynamic monitoring technologies for SHM. The review is classified into three parts, which include GNSS-based dynamic monitoring technologies for SHM, the improvement of GNSS-based dynamic monitoring technologies for SHM, as well as denoising and detrending algorithms. The significance and progress of Real-Time Kinematic (RTK), Precise Point Position (PPP), and direct displacement measurement techniques, as well as single-frequency technology for dynamic monitoring, are summarized, and the comparison of these technologies is given. The improvement of GNSS-based dynamic monitoring technologies for SHM is given from the perspective of multi-GNSS, a high-rate GNSS receiver, and the integration between the GNSS and accelerometer. In addition, the denoising and detrending algorithms for GNSS-based observations for SHM and corresponding applications are summarized. Challenges of low-cost and widely covered GNSS-based technologies for SHM are discussed, and problems are posed for future research.

“…One of the most important developments was the introduction of the digital rangefinder, which allowed to obtain more accurate measurements results. Next significant improvement in the measurements methods was the usage of the GPS satellite system (Liu et al 2012). The emergence of the GNSS satellite systems (Havasi 2012) has allowed to obtain the results of completely new quality along with limiting the time consumption and the costs of conducting the observations (lack of the need of the long-time reference of measurements to fixed points).…”

Mining exploitation has a negative impact on the natural environment. Voids created in the rockmass result in displacements and deformations of land surface. During planning and conducting the exploitation, the range of exploitation influence in the form of linear deformations is being determined. On the basis of mining-geological parameters of exploitation, the exploitation range of influences is calculated. According to the literature, many different ranges of exploitation influences can be determined depending on what has been the purpose of it. Different types of exploitation influence ranges can be distinguished, such as theoretical, damage or measurable. In the paper, the matters connected with determining those three types of the influence range are taken under consideration. The comparison of magnitudes of determined influence ranges is illustrated with two practical examples.Natural Hazards (2018) 94:979-997 https://doi.org/10.1007/s11069-018-3450-5( 0123456789().,-volV) (0123456789().,-volV)
