开采天然石材时对所采块料裂隙方面的特殊质量要求,在很大程度上限制了传统的爆破法开采工艺在采石和剥离工程上的使用。国家采矿技术监察委员会从保护资源出发,尽力限制使用爆破法开采天然饰面石材矿,而国产松土机械的功率小,在开采风化覆盖层时不可能广泛使用。因此,大多数矿床使用普通的采掘设备进行开采。在裂隙发达的风化岩层中,利用采掘设备的工艺效果大大下降。这拖延了现有露天
The special quality requirements in the mining of natural stone in the mining block cracks to a large extent limit the use of the traditional blasting mining process in quarrying and stripping engineering. The State Mining Technology Supervision Commission, starting from the protection of resources, tries its best to limit the use of blasting mining natural stone veneers, while the domestic power of loose soil machinery, mining weathered cover can not be widely used. As a result, most of the deposits are mined using normal mining equipment. In weathered fractured rock formations, the effectiveness of mining equipment is greatly diminished. This delayed the existing open air
