摘要
曲江公司开采的B4煤层易自燃,211炮采面在开采过程中出现高CO、高温等自燃预兆,采用上落山角注浆、老塘侧控风、洒浆等措施。
Spontaneous ignition signs such as high CO,high temperature occurred in the mining at 211 blasting mining face in Qujiang Colliery because of easy spontaneous combustion of B4 Coal Seam.The paper introduces measures such as grouting,old waste controlling wind and grout-sprinkling,which have achieved better results.
