摘要： 针对15201 工作面回采前期采空区内瓦斯超限、漏风量大、CO超限等技术难题，盛泰煤业通过技术研究，对
工作面回采前期采空区管理现状及问题进行了分析，并通过采空区埋管瓦斯预抽、高位裂隙带瓦斯预抽、综合防灭火以
及设置L 型风障等技术措施，防止采空区灾害事故发生。从实际应用效果来看，采取有效的措施后，在后期回采中工作
面采空区CO 体积分数降至0.001 2%以下，瓦斯体积分数控制在2%以下，进一步提高了采空区安全管理水平，保证了
工作面安全高效回采。

Abstract: Aiming at the technical problems such as gas overrun, large air leakage and CO overrun in goaf of 15201 working face
in the early stage of mining, Shengtai Coal Industry Co., Ltd. analyzed the current situation and problems of goaf management in
the early stage of working face, and through the technical measures such as gas pre-drainage by burying the pipe in goaf, gas
pre-drainage of high-level fracture zone, comprehensive fire prevention and control, and setting up L-shaped wind barrier, etc.
through technical research, to prevent the occurrence of disasters and accidents in goaf. From the practical application effect, after
taking effective measures, the volume fraction of CO in the goaf of the working face was reduced to less than 0.001 2% and the
gas volume fraction was controlled below 2%, which further improved the safety management level of the goaf and ensured the
safe and efficient mining of the working face.

Key words: working face; goaf; safety management; gas pre-drainage; comprehensive fire prevention and control; wind barriers
