摘　　要：新景公司是煤与瓦斯突出矿井,瓦斯治理是保证煤矿安全生产的重中之重。此次以新景公司3217掘进工作面为研究对象,对该工作面过陷落柱期间的区域综合防突措施方案的制定、各个环节钻孔的施工、区域效果检验等方面进行了分析。根据3217辅助进风巷区域防突措施过程中的遇矸情况及掘进过程中揭露的地质构造,把掘进区域分为不同的区段,制定了不同的瓦斯区域治理方案。在过陷落柱期间,相关防突数据指标均小于临界值,防突措施执行效果显著,顺利通过了该掘进工作面的陷落柱,对其他矿井过陷落柱期间的揭煤有很好的借鉴作用。Xinjing Company is a coal and gas outburst mine,gas control is the top priority to ensure the safety of coal mine production.Taking the 3217 heading face of Xinjing Company as the research object,this paper analyzes the formulation of regional comprehensive outburst prevention measures,the construction of boreholes in each link and the regional effect test during the period of the working face passing through the collapse column.According to the gangue situation in the process of outburst prevention measures in the area of 3217 auxiliary air intake roadway and the geological structure revealed in the process of excavation,the excavation area is divided into different sections,and different gas area control schemes are formulated.During the period of passing through the collapse column,the relevant outburst prevention data indicators are less than the critical value,and the implementation effect of the outburst prevention measures is remarkable.The collapse column of the heading face is successfully passed,which has a good reference for the coal uncovering during the collapse column of other mines.
