摘　　要：针对补连塔矿22306工作面上隅角氧体积分数偏低问题,采用了均压通风技术,有效地消除了上隅角氧体积分数偏低的安全隐患;系统介绍了均压通风技术的方案及步骤,通过风量、风压及上隅角氧体积分数等指标,综合评价了均压通风的效果。结果表明:均压通风技术能较好地解决上隅角氧体积分数偏低问题,同时,本次灾害治理探索能够为同类生产实践提供重要借鉴。Aiming at the problem of low oxygen volume fraction in upper corner of 22306 working face of Bulianta coal mine, the technology of even pressure ventilation can be used to eliminate the potential safety hazard resulting from the referred problem effectively. The detailed technology scheme and implementation procedures were introduced systematically. The indicators such as air volume, wind pressure, oxygen volume fraction in upper corner and so forth, can be applied to evaluate the practical effect of the technology. The results show that the technology can solve the problem of low oxygen volume fraction in upper corner successfully. At the same time, the research of this risk settlement can provide important lessons for similar production practice.
