密闭及其沿周注浆防火技术在尚庄矿的应用

摘要

The paper proposes the fire prevention technology with grouting by sealing wall and roadway along periphery,which effectively prevents the air leakage,poisonous and hazardous gas emission,temperature rise and coal spontaneous ignition in goaf,and guarantees the safety production in Shangzhuang Colliery.%尚庄煤矿采用对密闭墙及密闭沿周巷道进行注浆防火技术,有效防止了密闭漏风、瓦斯等有毒有害气体泄出、温度升高、采空区煤炭自然发火,保障了矿井安全生产。
