摘要
基于神东补连塔煤矿开采实践,对近距离煤层上覆特大采空区综采工作面在开采过程中出现的低氧问题进行分析总结,发现低氧现象呈现年度季节、当天时间、特殊天气等规律,并将低氧分为局部低氧、大面积低氧2大类。以补连塔煤矿22410综采工作面为研究对象,针对局部低氧提出了关键岗位人员管控、高概率低氧区域气体实时监测、关键区域设施设备配备、低氧预警及处置综合应急处置技术;针对大面积低氧提出了均压通风、"三网融合"应急联动、紧急救护综合应急处置技术,确保了矿井的安全生产。
Based on the mining practice of Shendong Bulianta Coal Mine,this paper analyzes and summarizes the low-oxygen problems in the mining process of the fully mechanized working face in the overlying large goaf of the close distance coal seams,and finds that the low-oxygen phenomenon presents the annual season,time of day,and special weather,and other laws,and divides low oxygen into two categories:local low oxygen and large area low oxygen.Taking the 22410 fully mechanized mining face of Bulianta Coal Mine as the research object,it proposes personnel management and control of key positions,real-time monitoring of gas in high-probability low-oxygen areas,equipment and facilities in key areas,low-oxygen early warning and comprehensive emergency treatment technologies for local low oxygen;aiming at large-area low oxygen,a comprehensive emergency response technology for pressure-equalized ventilation,"three-network integration"emergency linkage,and emergency rescue was proposed to ensure the safe production of mines.
