摘要
露天矿生产要求通过预裂爆破保护到界边坡岩石的完整性和稳定性,安家岭煤矿长期以来进行此项工作效果并不明显。为此组织相关技术人员对预裂爆破重新设计、优化施工并进行试验与评价,提高了爆破效果与质量。本文对成功经验进行总结,供同类矿山企业技术参考。
Production in open-pit mine requires to protect the integrality and stability of the rock in the circle of the slope through presplitting blasting.The presplitting blasting was performed in the production in Anjialing Mine,but no obvious positive results reached in the past.For this reason,the work of redesign the presplitting blasting was carried out by relevant technical staffs.The new design was tested with optimized construction scheme and the blasting test was evaluated.Tests showed that the new design upgraded the blasting quality and effect.The present paper summarizes the successful experience accumulated in the production and likes to share the technical success with other Mine of the kind.
