ABSTRACT

As a companion organism in the process of coal mining, coal gangue has been widely used in many fields, such as construction and the chemical industry, for many years. Using it as a backfill material for building foundations can not only reduce the environmental pollution caused by open-air stacking but also reduce the cost of gangue disposal. Under the premise of reasonable analysis of the feasibility of building land reclamation with gangue backfilling, this paper comprehensively analyzes the key technology of gangue backfilling and reclamation for construction land from multiple perspectives, such as planning site selection, design points, backfill elevation, and construction methods. Finally, the effect is introduced with an engineering example. The research results can provide references for related research and engineering design.
