Possibility of Mine Waste Dump remediation with Thermal Activity

The use of mine waste dump after coal mining causes a number of practical problems. The most important problems to resolve is the thermal activity. Since the mine waste dump contains residual amount of coal, this geological environment is susceptible to thermal activity. The thermal activity must be eliminated so the mine waste dump can serve as a foundation soil. The aim of this publication is to analyze the possibility of mine waste-dump remediation. Water injected into the soil can be used to extinguish the thermal activity. To eliminate the thermal activity may be used water. Another possibility is the application of CO2 or other gases. The application of these methods depends on the number of boundary conditions such as suitable terrain morphology and good sealing area. Grouting high quality blends is another way to prevent the spread of thermal activity in the affected area. A modern method, suitable for the termination of thermal activity is the Deep Soil Mixing. Interlacing rock material with inert material that will serve as the seal is another possibility. (C) 2015 Published by Elsevier B.V.
