A study of coal gangue used as road-building material

摘要：

The harm of coal gangue to the environment was illustrated in this paper.The feasibility of the application of coal gangue in road construction was analyzed by investigating its physical and mechanical properties and the successful examples worldwide.The selective crushing and separation process and the selective crusher were introduced to treat coal gangue for road-building material.Finally,the potential influences of coal gangue used as road-building material on environment were evaluated which demonstrated that the application of coal gangue in road construction had favorable economic,social and environmental benefits.
