Study on fire-extinguishing of spontaneous combustion wastes and reclamation
- Datong Coal Mining Administration, Datong City (China)
Spoil banks of coal mining have become an important aspect for environmental pollution. Toxic and pernicious gases resulting from the spontaneous combustion of wastes are much more serious pollutants. The authors have gained certain experience in preventing the spontaneous combustion of spoil banks and in fighting fires. The paper describes a revegetation test for the spoil bank. Using a spoil bank in the frigid and arid area in Shanxi, the paper describes the tests and results of the physical and chemical characteristics of the wastes and thoroughly analyzes the influence these characteristics have on the revegetation of the spoil bank. Revegetation promotes weathering of the wastes and mitigates erosion of the spoil bank. It was found that the wastes do not store adequate water, so that in the early stage of planting, irrigation is recommended. The pH of the wastes is suitable for plant growth, but in the case of fire fighting, care should be taken to mitigate the damage to lime emulsion alkalinity.
