施工超前钻孔是预防掘进工作面瓦斯喷出和瓦斯突出的局部性有效措施,但在掘进工作面掘进过程中施工相对较繁琐,工程量较大,也容易影响正常掘进工作。本文介绍了在大隆矿东三采区七层瓦斯富聚区域煤巷综掘工作面,通过科学合理设计,合理组织施工超前钻孔,并边掘边抽,有效的预防了高瓦斯区域综掘工作面瓦斯和水的异常涌出,保证了安全快速掘进,取得了较好的成功经验。
The advanced drilling in construction is an effective measure to prevent gas outburst and gas outburst in tunneling work face. However, the excavation face excavation process is relatively tedious and the construction volume is relatively large, which also easily affects the normal excavation work. This paper introduces the fully mechanized mining face of the coal roadway in the seventh coal accumulation area in the East Third Mining Area, Dalong, through scientific and rational design, reasonable construction of advanced drilling, and edge pumping, effectively preventing the high gas area Excavating face gas and water abnormal emission, to ensure the safe and fast heading, and achieved good success experience.
