摘要
为了解决巷道掘进受瓦斯赋存影响较大,巷道无法保证安全快速掘进的问题,本文结合作业区的工程地质背景,分析了影响其掘进作业的原因,并针对性地提出了采取工作面长短钻孔相结合的工作面瓦斯治理方式。现场实践表明:优化后的工艺技术有效减少了工作面瓦斯涌出量,保证了巷道安全快速掘进,具有较高的经济价值和社会价值。
In order to solve the problem that roadway excavation is greatly affected by gas storage and roadway can not ensure safe and rapid excavation,combined with the engineering geological background of the operation area,this paper analyzes the reasons affecting its excavation operation,and puts forward the gas treatment method of combining long and short boreholes in the working face.The field practice shows that the optimized technology effectively reduces the gas emission of the working face,ensures the safe and rapid excavation of the roadway,and has high economic and social value.
