自动监测露天矿穿孔参数的主要目的,是优化穿孔能力及评价钻头、钻杆和穿孔质量,更重要的是通过穿孔获得更及时和更详细的岩性数据,以便随着采矿的推进作出战术决策。采矿的推进与岩石的可掘性、爆破设计、排水、边坡稳定和品位控制有关。穿孔监测在欧洲的应用比北美更为广泛。瑞典使用类似的装置记录钻速,并结合应用孔内电视,其目的是根据岩石强度和裂隙特点获得地下岩层质量数据。英国进行穿 The primary purpose of automatic monitoring of perforation parameters in surface mines is to optimize perforation capabilities and evaluate drill bit, drill pipe and perforation quality and, more importantly, to obtain more timely and more detailed lithologic data through perforation in order to make tactical decisions as mining progresses . Mining advances are related to rock digability, blasting design, drainage, slope stability and grade control. Perforation monitoring is more widely used in Europe than North America. A similar device was used in Sweden to record the penetration rate, combined with the use of a hole television, to obtain subsurface rock quality data based on rock strength and fracture characteristics.
