黑龙江省典型矿区生态恢复现状与策略

Status and Strategy of Ecological Restoration of Typical Mining Areas in Heilongjiang Province

黑龙江省矿产资源非常丰富,矿种数占全国的56.12%。典型的矿山包括石墨矿、砂金矿和煤矿,其石墨资源储量占全国第一位,黄金占第二位,煤炭也具备相当的优势。由于开采时间长、中小型矿山占99%以上,尾矿和固体排放物对环境污染非常严重。为此,在对石墨、砂金、煤炭矿山开采、环境污染、生态恢复现状分析的基础上,提出了黑龙江省典型矿区尾矿和固体废弃物堆放地植物恢复策略。

Heilongjiang province is rich in mineral resources, accounting for 56.12% of the national total type number of minerals. Typical mine including graphite ore, alluvial gold and coal, and the graphite resources reserves of our country first, gold accounts for the second, coal also has considerable advantages.Because of long mining time, small and medium-sized mines accounted for more than 99%, tailings and solid emissions on the environment pollution is very serious. Based on the analysis of graphite, alluvial gold and coal mine exploitation, environmental pollution and ecological restoration, this paper put forward the strategy of plant recovery from tailings and solid waste dumps in Heilongjiang province.
