Abstract
An abandoned or inactive portion of an asbestos open pit or underground shaft mine is used to permanently bury asbestos waste material produced from asbestos mining, asbestos processing and building demolition or renovation. The asbestos waste material is deposited in the mine, preferrably, in sealed containers and covered with tailings or non-asbestos material, such as soil or the like. As the asbestos waste material is deposited in the mine, it is covered with a layer of tailings or non-asbestos material within any twenty-four hour period. This procedure is repeated until the mine if filled and ultimately covered with a layer of non-asbestos material. A layer of vegetation is then planted on top of the former mine site.
