精细爆破在煤矿岩巷掘进中的应用

Application of Fine Blasting in Rock Roadway Excavation in Coal Mine

本文主要分析了精细爆破在煤矿岩巷掘进中的应用情况,重点介绍了提高爆破效率、改善生产质量的有效措施,它不仅会影响巷道掘进过程中的进度,也会提高出矸量以及后续支护材料的消耗量,同时还具有稳定性和安全性的特点。通过对该问题的研究和分析,可以进一步清晰当前精细爆破在煤矿岩巷掘进作业中的重要性,也能进一步了解到提高爆破效率、改善爆破水平、增加进尺、确保成型是解决当前问题的有效措施,需要加强重视。

This paper mainly analyzes the application of fine blasting in rock excavation of coal mine,and emphatically introduces the effective measures to improve blasting efficiency and production quality.It will not only affect the progress of roadway excavation,but also increase the amount of gangue and the consumption of subsequent supporting materials,and has the characteristics of stability and safety.Through the research and analysis of this problem,we can further understand the importance of fine blasting in rock excavation in coal mines,and further understand that improving blasting efficiency,improving blasting level,increasing footage and ensuring molding are effective measures to solve the current problems,which need to be paid more attention to.
