清河二煤矿局部通风阻力对矿井通风影响的技术分析

摘要

On the measurement and analysis of progressing ventilation resistance of the ventilation system in Qinghe Mine II, the study concluded that the main cause was the local ventilation resistance. Then, a reform plan on the ventilation was proposed.%测定并分析了清河二煤矿通风系统进行通风阻力，矿井局部通风阻力的影响是主因；据此提出清河二煤矿改造通风系统的思路。
