Monitoring of Subsidence Over a Continuous Miner-Based Coal Mine Caving Panels Using PS-InSAR Technique

Remote sensing monitoring of coal mining collapse and analysis of ecological restoration model in China

“…Remote sensing technology has the characteristics of large-area synchronous observation, strong timeliness, low cost, and objective response to the state and changes of the ground. However, the scope of prior studies and monitoring of coal mining collapse is currently limited, either to a single mining area or to a single province and city, and there is less remote sensing monitoring of coal mining collapse across China [12][13][14][15][16][17][18][19][20][21][22][23][24][25]. Therefore, based on the previous studies, this paper makes full use of the existing domestic high-resolution remote sensing data to monitor the information of coal mining collapse nationwide, and the results obtained can provide data support for the supervision and comprehensive prevention and control of coal mining collapse nationwide to a certain extent, and provide a reference for the ecological restoration of coal mining collapse, which has certain research significance.…”

Study on Surface Deformation and Movement Caused by Deep Continuous Mining of Steeply Inclined Ore Bodies

“…Because the mined terrain is relatively complex, some mines cannot monitor the surface deformation using GPS technology, so Chen, Agnieszka, and Fan et al [15][16][17] monitored the surface deformation caused by deep mining using InSAR monitoring technology, revealing the distribution and deformation law of surface deformation in time and space. Until today, InSAR monitoring technology has been widely used in the study of surface deformation caused by deep orebody mining and has derived different data processing methods such as PS-InSAR [18], AD-InSAR [19], SBAS-DInSAR [20,21], etc., but these methods are based on historical data for analysis and cannot study future deformation development trends. Numerical simulation technology has developed from the last century to today and is gradually maturing.…”

Specifics and practical examples of low-hazard industrial waste utilization for filling technogenic cavities

“…These activities are particularly important if the regions have extensive industrial and civil infrastructure. Mines and quarries that do not use backfilling of the mined-out area form zones of shear and significant failures on the earth's surface, which creates a technogenic hazard and reduces the land potential of the territories [9,10]. In open-pit mining operations, not enough attention is paid to the activities of backfilling mined-out quarry cavities.…”
