摘　　要：针对开元煤矿进风巷掘进工作面掘进过程中煤与瓦斯突出问题,分析了开元煤矿及其进风巷掘进工作面现有的工程地质情况,设计了区域防止煤与瓦斯突出的措施,并根据设计完成了防止煤与瓦斯突出的施工;开展了预抽钻孔有效控制范围界定、评价单元划分及预期指标合格判定,并进行了预抽瓦斯效果现场实测验证。验证结果表明,预抽瓦斯效果达标,为类似地质条件下煤矿进风巷掘进工作面区域防止煤与瓦斯突出提供了技术借鉴。According to the coal and gas outburst problems occurred in the driving process of the air in-take gateway in Kaiyuan Mine,the paper had an analysis on the available engineering geological condition of Kaiyuan Mine and the air intake gateway driving face and had a design on the measures of the.regional coal and gas outburst prevention.Based on the design,the construction of the coal and gas outburst prevention was completed.The definition on the effective control range of the gas pre-drainage was conducted.The unit division was evaluated and the expected index qualification was judged.Also a verification was conducted on the site measurement of the gas pre-drainage effect.The verification results showed that the gas pre-drainage effect reached the standard and could provide the techni-cal references to the regional coal and gas outburst prevention of the heading face in the mine air intake gateway under the similar geological condition.
