Study on the Comprehensive Consolidation and Ecological Reclamation of Coal Mining Areas in Jiaozuo

Abstract:

Land subsidence and ecological problems caused by underground mining threaten seriously the sustainable development of mining areas. An example of coal mining areas in the northwest of Henan province is studied. The subsided areas amount to 70 km2 and the maximum subsided depth is more than ten meters. A series of serious problems, such as soil erosion, soil fertility declining and vegetation degeneration, are caused by land subsidence. Engineering measures are adopted for the subsided lands in hilly areas to rebuild the land as types of terrace and gentle slope, and that in the plain to renovate with methods, such as drainage, filling with coal waste rocks or fly ashes, deepening lower subsidence and filling higher subsidence. At the same time, biological measures, such as planting peanuts, soybean and other legume perennial or annual herbs, and adding organic fertilizer are used to improve the reclaimed soil quality.
