露天采场、尾煤坝的复垦,矿山酸性水的中和以及防止煤自燃等方面的工作目前已卓有成效地展开。新的选矿技术能明显地降低煤中的灰分及含硫量。被称为“净化”燃烧技术的应用,有助于减少固体废料量及气体污染物的排放量。本文论述了用于单一开采阶段中的防护措施、最有前途的煤选别及燃烧技术。 Open pit mining, tailings dam reclamation, acid mine water and coal spontaneous combustion and other aspects of the work has been carried out effectively. The new beneficiation technology can significantly reduce the coal ash and sulfur content. Known as the “clean-up” combustion technology, it helps reduce the amount of solid waste and the emission of gaseous pollutants. This article discusses the protective measures used in a single production phase, the most promising coal sorting and combustion technologies.
