硐室爆破在石灰石矿开采中的应用

Application of Chamber Blasting in Limestone Mining

天龙水泥厂石灰石矿在开采中应用了硐室爆破。本文所介绍的硐室爆破的特点是 ,结合爆区条件 ,布置多层硐室 ,采用了条形药包和集中药包 ,且各层药包自下而上分段毫秒微差起爆。爆破取得了成功 。

Chamber blasting is adopted in mining limestone for Tianlong Cement Plant. For the chamber blasting operation described in this paper, multilayered chambers are designed according the field conditions, stripe cartridges and confined cartridges are adopted. From bottom to top for the layers, staged MS-delays are designed. The blasting operation is very successful, offering reference value for chamber blasting under similar conditions.
