Comparison of coal gangue treatment scheme in Northern Shaanxi——Taking Xiaobaodang Coal Mine as an example
Coal gangue treatment is one of the biggest industrial solid wastes in our country.In order to effectively deal with a large amount of gangue in Xiaobaodang Coal Mine,considering the gangue characteristics of the mine,and comparing and analyzing the existing utilization and treatment methods,efficiency and applicable conditions,we put forward an effectively scaled treatment technology,that is,prioritizing the underground filling scheme.According to the geological conditions,min-ing geological conditions and underground spatial distribution,applicable feasibility is evaluated,indicating that goaf grouting filling via surface drilling is feasible.Thus,coal mine underground space can be scientifically and rationally used to solve the problem of mine solid waste treatment,which is of important reference for other mines.
