露天矿采空区爆破方法的探讨

Discussion on blasting methods in the goaf of open-pit mine

由于水文地质或原井工开采改为露天开采等原因,导致许多矿山在露天开采时区域内存在许多无法确定的溶洞、采空区、陷落柱等,严重影响了矿山开采的生产进度计划和生产安全。以平朔东露天矿采空区的台阶松动爆破为例,对采空区采用爆破方法处理的注意事项及具体方法进行探讨,进一步总结完善采空区的爆破方法和施工技术。

Because of the hydrogeological or underground mining to open-pit mining and other reasons,many mines has many uncertain caves,goaf,collapse columns in the coal mining area,which seriously affect the mining production schedule and production safety.This article takes the goaf blasting as an example,discusses the cautions and specific methods for blasting treatment goaf,further improves the blasting method and construction technology of goaf.
