摘要
榆家梁煤矿52209工作面属孤岛工作面,针对工作面在回采过程中出现了不同程度的低氧现象,介绍了工作面均压通风原理、均压系统构成及其使用过程中应注意的相关事项。52209通过采取"U"型均压通风措施有效解决了低氧问题,保证了工作面的安全开采。
Aiming at varying degrees of low-oxygen content conditions during mining process in 52209 working face of Yujialiang Coal Mine which belonged to isolated working face,the even-pressure ventilation principle,system structure and some matters needing attention during operating were introduced.Through adopted U-type even-pressure ventilation meatures,the low-oxygen problems were solved and it ensured the safety mining of the isolated working face.
