摘　　要：研究了无烟煤中配加20％～50％的当地瘦煤的混合煤的着火点、爆炸性和燃烧性能。结果表明，在攀钢现有条件下，喷吹这种混合煤是安全的，有利于提高系统的磨煤效率和煤粉的燃烧性，从而扩大喷煤量和降低喷煤成本。The authors have studied the fire point,explosion properties and combustion characteristics of coal blend which contains anthracite with 20%～50% semi-bituminous coal. The results show safely Injection of the coal blend under the existing condition of Pangang blast furnace coal injection system can be realized. It is beneficial to improvement of coal grinding efficiency and combustion properties of pulverized coal; therefore,resulting in the Increase of coal injection rate and decrease of cost of coal injection.
