影响巷道周边眼痕率因素分析

Analysis of factors affecting the rate of eye spot around roadways

巷道周边眼痕率对巷道成型质量、节支降耗起决定性的作用,为使爆破后巷道成型符合轮廓线设计要求,提出巷道周边眼痕率影响因素:周边眼间距、装药质量、钻孔质量、岩体力学性质、人为因素和施工制度,并对其进行探讨分析,对实现巷道快速安全掘进具有重要意义。

The surrounding hole mark ratio plays a decisive role in the roadway forming quality, energy savings, requirements for the blasting after forming a tunnel with the design outline of proposed roadway surrounding the hole mark ratio factors surrounding the eye spacing, charge quality, the quality of the drilling, the mechanical properties of rock mass and human factors and system construction, and carries on the thorough the discussion and analysis is very important to achieve quick and safe excavation roadway.
