Abstract

Different types of reclaimed land require different land reclamation techniques. This study uses previous research to divide the mining areas in China into 10 land reclamation zones according to the climatic zones, soil conditions and the distribution of mines. The country is divided into the following zones: the northeast plains and hills region, the Huang-Huai-Hai Plain region, the Yangtze River Basin region, the southwest mountainous and hilly region, the central mountainous and hilly region, the southeast coast hilly region, the northwest arid semi-arid region, the Loess Plateau region, the Inner Mongolian grasslands region, and the Tibetan Plateau region. The subsided, excavated and occupied lands in the mining areas are divided into two categories, suitable for reclamation and unsuitable for reclamation, based on geological and geomorphological characteristics, climate, hydrology, soil conditions, and social demand. In addition, the suitability of waste land in each area is evaluated. This study provides a basis for waste land reclamation in Chinas mining areas.
