Monitoring underground coal mining - induced subsidence
Monitoring of mine subsidence by means of classical methods such as optical levelling or Global Positioning System (GPS) surveys can reveal deformations with sub-millimetre to subcentimetre precision for localised areas. However, to provide data on a reasonably dense two-dimensional (2D) benchmark grid are costly and time-consuming for all but the smallest areas. Moreover, a regular re-survey o...
متن کاملMonitoring a Large and Complex Land Subsidence in Coal Mining Areas with a Small-baseline Interferogram Stacking Technique
China is the world’s largest coal-producing country and mining-related land subsidence happens almost in every coal mining area. In north-west China, land subsidence in coal mining areas is mainly caused by underground mining activities and uncontrolled burnings of subsurface coal seam. As Hoffmann (2004) reported, burning coal-seams can result in extensive subsidence of several meters and typi...
متن کاملA Study on the Reclamation and Ecological Restoration in Subsidence Land in Chinese Coal Mine Area
Arbuscular mycorrhizal fungi (AMF) technology of bioremediation becomes one of the most hotspots in the research on coal-mining subsidence land. This article based on amorpha fruiticosa planting in the mining subsidence of Shendong mining area as a study object, arbuscular mycorrhizal fungi was vaccinated on amorpha fruiticosa after different monitor time, respectively measures are used to anal...
متن کاملIntelligent Planning of Tourism Scenic Routes Based on Genetic Algorithm in Coal WANBEI Mining Subsidence
Aiming at the problem of tourism scenic route planning, this paper studies and analyzes the combined influence of terrain slope and surface properties on vehicle route planning. The “window moving method” is introduced to carry out early slope calculation and traffic ability analysis for the terrain, roughness evaluation index is established respectively for wheeled and tracked vehicles and the...
متن کاملEcological impacts of large-scale disposal of mining waste in the deep sea
Deep-Sea Tailings Placement (DSTP) from terrestrial mines is one of several large-scale industrial activities now taking place in the deep sea. The scale and persistence of its impacts on seabed biota are unknown. We sampled around the Lihir and Misima island mines in Papua New Guinea to measure the impacts of ongoing DSTP and assess the state of benthic infaunal communities after its conclusio...
