煤开采中的环境保护途径

Environmental protection approaches in coal exploitation

对采煤行业可直接采用的环境保护热点技术及途径进行了综述.提出要主动应对日益严格的环境法规,煤炭行业可通过加强煤转化、洁净煤技术、煤层瓦斯纯化和转化、煤矸石粗放与深度加工等方面的投入和联合研究,来提高燃煤产品质量,扩大煤的燃料和非燃料应用领域,降低煤开采综合成本,从而改善整个煤炭行业的经济效益.

It was reviewed that the hotspots in environmental protection processes and approaches directly adoptive for the coal mining industries in this paper. It is proposed that in the face of the increasingly severe regulations for environment protection,they were able to reinforce the investment and combined investigations with the relative organizations in the conversion and cleaning technologies of coals, concentration and conversion of coal seam gas, coarse and deep processing of coal gangues so as to enhance the coal rank,enlarge the utilized fields of coals,make the integrated costs fall and improve the economic actuality in the whole coalmining industries in China.
