摘 要:为解决邢东矿2129工作面在深采区大地压、巷道变形严重、采空区瓦斯向外涌出等各类地质因素影响下,有效回收工作面剩余煤炭资源,采取喷涂化学浆封堵瓦斯释放、合理运用瓦斯抽放系统、调整二水平通风系统增加工作面风量、进回风隅角排沙袋墙封堵采空区瓦斯等一系列综合瓦斯治理技术。结果表明,回风流瓦斯浓度稳定在0.2%,治理效果明显,能够有效的降低工作面瓦斯涌出量。In order to effectively recover the remaining coal resources in No.2129 Face of Xingdong Coal Mine under the influence of various geological factors such as ground pressure in deep mining area,serious roadway deformation,and gas emission from goaf,a series of comprehensive gas control technologies were adopted,such as sealing gas release by spraying chemical slurry,rational use of gas drainage system,adjustment of two-level ventilation system to increase the air volume of working face,and sealing goaf gas by sandbag wall at the corner of inlet and outlet air.The results show that the gas concentration of the return air flow is stable at 0.2%,and the treatment effect is obvious,which can effectively reduce the gas emission of the working face.
