Xinhai can customized the mining technology for each mining plant, such as open-pit mining process, underground mining process, which can guarantee the idea mining processing effect.
Horizontal slices with certain thickness are defined to extract ore from top to bottom until reaching the ultimate or temporary boundary and forming the ultimate or temporary slope.
According to the depth of blasting holes, there are two mining methods: short-hole room and pillar stoping; medium- and deep-hole room and pillar stoping.
Deep-hole drill jumbo is adopted to construct downward parallel deep holes in the drilling chamber.
Open pit mining usually covers the whole boundaries. Horizontal slices with certain thickness are defined to extract ore from top to bottom until reaching the ultimate or temporary boundary and forming the ultimate or temporary slope. It impacts both the production technologies and economic benefits in the initial stage.
Post pillars are reserved in the stope for support. According to the depth of blasting holes, there are two mining methods: short-hole room and pillar stoping; medium- and deep-hole room and pillar stoping. The former adopts short-hole rock drill for orebodies with a thickness of less than 3-4m, and ore is transported by electric rake or scraper to the stope orepass. The latter adopts medium- and deep-hole rock drill for orebodies with a thickness of 5-30m, and ore is transported by scraper onto the dump truck. Low costs, easy mechanization, and simple technology.
Deep-hole drill jumbo is adopted to construct downward parallel deep holes in the drilling chamber. After side caving, ore is discharged by scraper into orepass. Ore block has two-stage stoping. After the first-stage stoping, mined-out areas are filled with cemented filling materials to form stable support. Then the second-stage stoping is carried out. Large production capacity, centralized management, low mining costs, and high degree of safety.
