对于所开采的天然石材荒料在质量方面的特殊要求,使裂隙的存在不仅在开采时,而且在进行剥离工作时,在很大程度上都限制了传统的爆破工艺方法的使用。设计开采天然石材荒料的企业现行标准工艺文件只肤浅地阐述开采风化剥离岩石的问题,对于进行爆破作业时的预防措施缺乏应有的论证,也没有具体地介绍有关机械松土的应用技术问题。苏联国家采矿技术监察委员会从保护资源的完整性出发,最大限度地限制使用爆
The special quality requirements for the natural stone blocks mined allow the use of conventional blasting methods to a large extent restricted not only during mining but also during the peeling operation. The current standard technical documents for designing and mining natural stone blocks only provide a shallow explanation for the problem of weathered and peeled rocks, lack of proper justification for preventive measures in blasting operations, and no specific technical application concerning mechanical loosening . From the point of protecting the integrity of resources, the Soviet Union’s National Mining Technology Monitoring Board limits the use of explosives to the maximum
