摘　　要：基于5316回采工作面底板严重突水和局部区域瓦斯含量异常的情况,通过分析该回采工作面采用无煤柱开采后采空区漏风场的特点,结合开采工作面所处煤层瓦斯的涌出源、瓦斯涌出量的影响因素及瓦斯涌出规律,制定了瓦斯综合治理方案。结果表明:该回采工作面采用无煤柱开采后,可有效控制矿压显现及底板突水;采用监测预警技术、均压通风技术、瓦斯抽放技术三种技术相结合的瓦斯综合治理技术后,有效控制了瓦斯超限等情况。随后的生产中,底板突水事故与瓦斯超限事故均未在工作面推进过程中出现。该技术对类似地质条件下的煤矿开采工作具有一定借鉴作用。Based on abnormal gas content in local area and water inrush in 5316 recovery mining face,by analyzing features of air leakage field after no coal pillar mining,combined with the source,volume and law of gas emission,the comprehensive prevention and control of gas was settled.The result showed that no pillar mining enables to effectively control mine pressure display and water inrush.Gas out of limits was controlled with monitoring early warning,pressure ventilation and gas drainage technology.Water inrush in floor and gas out of limits were prevented after the adoption of the technology,with significant reference for similar mining.
