Coal is the basic resource underpinning energy generation in China, however, constant, large-scale mining of coal results in many problems such as ecological destruction of mining areas. As a result, backfilling of solid waste underground is proposed to control strata and surface subsidence and to protect the environment. At present, these materials, such as granular material, cemented.

1.Most open-pit mines in China are concave and the surface is uneven. After the material transported are lifted to the surface, the unloading level is different, which requires the level of the unloading point of corrugated sidewall belt conveyor with large inclination varies with the surface height. 2.There are coal seams in the open-pit coal mine, so the position of receiving point of.
The reclamation of surface (opencast) coal mines is not always successful there remains a legacy of degraded land that burdens local communities. This article evaluates a community-oriented, low-cost means of geoecological regeneration, the “Cradle for Nature” strategy, which uses mosaic tree planting to foster positive natural ecological processes.
