目前煤场贮煤氧化自燃变质,风吹雨淋流失严重,污染环境。就鞍钢而言,灵山煤场每年贮存动力煤30万吨,其它单位也有很大的贮量,但缺乏一套科学的管理方法。为了解决这些问题,鞍钢安全技术处安全技术研究所和鞍钢原燃料处灵山煤场从1981年底开始对煤堆保护层这个新课题进行研究,经 Coal coal spontaneous combustion of the coal field metamorphism, serious loss of wind and rain, polluting the environment. As far as Anshan Iron and Steel is concerned, Lingshan Coalfield stores 300,000 tons of steam coal a year, while other units also have a large storage capacity but lack a set of scientific management methods. In order to solve these problems, Anshan Iron and Steel Safety Technology Institute of Safety Technology Institute and the Anshan Iron and Steel Raw Materials Department Lingshan Coal Field from the end of 1981 began to study the new subject of coal pile cover,
