摘　　要：针对上榆泉煤矿综放工作面回风隅角附近低氧问题开展分析研究,根据实地调研,对导致低氧现象发生的气压、温度、湿度主要因素进行实时监测并建立数据库,进而分析地表温度、大气压对工作面低氧现象影响途径和程度,提出对综放工作面低氧现象超前预测预警的理念,为综放工作面现场安全生产提供必要信息,也为采取低氧治理措施提供基础依据。An analysis and research were conducted on the low oxygen problem near the return air corner of the fully-mechanized caving face in Shangyuquan Coal Mine.Based on field research,the main factors causing low oxygen phenomenon were monitored in real-time,including air pressure,temperature,and humidity,and a database was established.The impact of surface temperature and atmospheric pressure on low oxygen phenomenon in the working face was analyzed,and the concept of advanced prediction and early warning of low oxygen phenomenon in the fully-mechanized caving face was proposed.This provides necessary information for on-site safety production in the fully-mechanized caving face and a basic basis for adopting low oxygen treatment measures.
