摘　　要：为了保证东曲煤矿18304工作面开采过程中免受瓦斯及粉尘灾害的影响,对煤矿已有资料和相关安全规定进行分析,制定了工作面风排加抽采的瓦斯综合治理措施及安设防尘设施与超前钻孔注水相结合的粉尘防治措施。实际应用效果显示,18304工作面瓦斯抽采系统及粉尘防治措施满足相关安全规定,并且在工作面开采过程中,瓦斯浓度长期低于0.5%,粉尘浓度长期低于160 mg/m3,说明18304工作面的瓦斯及粉尘治理措施取得了较好的应用效果。In order to ensure that the 18304 working face of Dongqu Coal mine will not be affected by gas and dust disasters during the mining process,the existing data and relevant safety regulations of the coal mine are analyzed.The comprehensive gas control measures of air exhaust and extraction of the working face and the dust control measures of installing dust-proof facilities and advancing drilling water injection are for⁃mulated.The practical application results show that the gas extraction system and dust control measures of 18304 working face meet the relevant safety regulations,and in the process of working face mining,the gas concentration is lower than 0.5%for a long time,and the dust concentration is lower than 160mg/m3 for a long time,which shows that the gas and dust control measures of 18304 working face have achieved good ap⁃plication results.
