跨采区复采工作面CO来源分析及防火技术研究

Analysis of the mining area complex face CO source and Research on fire prevention technology

在论述煤矿井下跨采区复采工作面掘进期间CO来源分析的基础上,重点强调减少漏风率,采用高效灭火剂混合浆液进行采空区预防性灌浆的技术,确保跨采区复采工作面安全回采。

BaSed on the mining of mining area in underground coal mine heading analysis during the CO source, with emphasis on de＇creasing air leakage rate, use of fire extinguishing agents Of high efficiency mixing slurry gob preventive grouting technology, ensure that the mining area mining accident in working face. !
