Characteristics of coal gangue of jurassic coal field in Northern Shaanxi
Bulk solid waste is the core field of comprehensive recycling of resources.As the industrial solid waste with the largest discharge in China,its comprehensive utilization is the inevitable requirement for waste-free city and ecological civili-zation construction in the new period.On the basis of combining data review,research practice and statistical analysis,the research and application status of coal gangue is systematically analyzed.At the same time,considering the reality of north-ern Shaanxi,based on cycle development concept of industrial ecological and ecological industrialization,and combined with practice research,we put forward the proposals of the gangue blending collaborative industrial power generation,gangue backfill collaborative geological environment management,gangue broken collaborative soil ecological restoration,gangue preparation collaborative building materials application,and the ground-underground ecological restoration.Our study pro-vides reference for the comprehensive utilization of coal gangue bulk solid waste and the green and low-carbon development of the industry.
