The evaluation of construction and utilization path of multivariate information database of solid waste from coal

Taking the solid waste from coal in Kuangou Coal Mine and Tunbao Coal Mine in Xinjiang as the research object,the physical and chemical properties of solid waste from coal were systematically tested. The model of hierarchical analysis and evaluation of potential utilization path of solid waste from coal was constructed,and the potential utilization grade of solid waste from coal was divided. Based on Python-Tkinter library,the physical and chemical properties database of solid waste from coal was developed and applied. The results show that:(1) The quality of solid waste from coal in Kuangou Coal Mine is better than that in Tunbao Coal Mine,and the utilization grade of gangue in working face and coal preparation plant is higher than that of waste dump. (2) The potential optimal utilization paths of gangue in working face and coal preparation plant are shotcrete material,grouting material,filling material and cement material. The potential optimal utilization of gangue in waste dump is shotcrete material and land reclamation. The research results provide a theoretical basis for systematically analyzing the potential utilization level of solid waste from coal,and provide reference for the construction and resource utilization of information system of solid waste from coal in other mining areas in Xinjiang.
