预裂爆破在副井卷扬机基础拆除中的应用

摘要

在拆除爆破中运用孔间间隔装药的技术手段，成功对卷扬机基础上的圈梁实施预裂切割。不仅降低了工人的劳动强度，缩短了施工工期，而且为该技术在预裂爆破中的运用，提供了宝贵的经验和依据。%The use of technical means "hole interval charge in demolition blasting" cuts hoist beam on the basis of pre split successfully. It not only reduces the labor intensity, shortens the construction period, but also provides valuable experience and basis for the use of technology in presplit blasting.
