ActiveTest method of leaching for coal and coal refuse
煤和煤矸石淋溶试验方法
Application Summary AI generated
This standard specifies the laboratory test method for simulating the leaching behavior of coal and coal refuse under rainfall or water immersion conditions. It is applied in the mining and environmental protection industries to assess the potential release of hazardous elements (e.g., heavy metals, sulfates) from solid coal materials into water sources. The method is used for environmental impact evaluations, waste classification, and pollution control planning at coal mines and coal preparation plants.
