煤矿均压通风安全技术及应急处置措施

Ventilation safety technology and emergency disposal measures of mine

基于永胜煤矿2307工作面在之前开采过程中出现低氧的情况,根据该矿地质概况、工作面通风方式以及附近工作面采动影响情况的分析,找到出现工作面低氧现象的具体原因,为此改造工作面的通风方式,采取"U"型均压通风措施很好解决了低氧问题,保证了工作面安全高效生产。

Based on the low oxygen of previous mining in 2307 working face of Yongsheng Mine,based on geological survey,working face ventilation,the reason of low oxygen was found,the ventilation was improved,U all pressure ventilation measures solved the problem,ensuring the safe production.
