摘要
为了解决自燃煤层近距离上覆小窑火区下开采工作面CO易超限的难题,通过对平朔矿区井工二矿21110工作面开采期间CO超限的原因分析,结合现场实际情况,运用监测监控、封堵漏风、水封、注浆和配合跳采技术等综合治理手段,有效解决了工作面CO超限问题,确保了21110工作面安全回采。
In order to solve the problem of CO overrunning on mining face under overlying small kiln fire zone in close-distance coal seam with spontaneous combustion,with the analysis of CO overrunning during mining period on 21110 working face in No. 2 coal mine of Pingshuo mining area,combining with the actual situation,monitoring,air leakage sealing,water seal,grouting and mining technology are integrated,to effectively solve the CO overrun problem,and to ensure the safety mining of 21110 working face.
