Analysis and prediction of low oxygen in the return air corner of fully-mechanized caving face in Shangyuquan Coal Mine
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.
