Stone mining machinery
Stone mining machinery is the first production machinery used in the production process of architectural decorative stone, which includes stone exploration machinery, stone mining machinery, stone transportation machinery and related tools, auxiliary materials, etc. Many types of stone mining machinery are formed by using other mining exploration and mining machinery; or slightly improved on their basis; there are also practical machinery developed according to the requirements of stone block production.
Its main function is that the exploration machinery mainly finds stone varieties suitable for building decoration stone, and determines the quality, color and reserve, analyzes the physical and chemical properties of the quality, and determines the market use value and economic value. The geological report provides a detailed basis; the main function of the mining machinery is to peel off the covering layer from the mountain, transport the muck, separate the stone wool from the mountain, reshape the stone wool to obtain the block, and transport the block to the designated location until the processing plant. .
In the application process of stone mining machinery, it mainly includes the following stages and types of machinery: the machinery for stripping the mine covering layer and the transportation stage includes: excavators, front-end loaders, forklifts, rock drills and supporting tools; mining, separation, and movement of stone blocks. Our machinery includes: rock drills, down-the-hole drills, diamond beaded wire saws, diamond circular saws, gun rod cranes, capstone machines, car cranes, air compressors, chain arm saws, shaping machines, forklifts, flame cutting machines, air pressure packs, Hydraulic packs, splitting machines, cutting machines and supporting tools, etc.; the machinery in the stone block transportation stage includes: heavy transport vehicles, forklifts, winches, excavators, front-end loaders, gun-bar cranes and supporting tools and other stone mining machinery associations Different supporting combinations are formed due to various factors of the mine. Such as different types of stone, such as different types of marble, granite, slate, choose different machinery; also choose different stone machinery combinations due to different types of stone, such as Brazil blue, Namibia blue , Carrara white; also use different supporting combination machinery due to the different mining methods used, such as step method, hole mining method; also use different mining methods due to the different mineralization forms of stone in nature, and then choose different Stone mining machinery, such as oval, stacked, massive, and columnar; there are also various mechanical combinations due to the different shapes of the stone affected by nature, such as deeply buried oval, raised stacked, and thick covering. Layered, large bedrock at the surface, upright columns, etc.
Since stone mining is to obtain as many large blocks, regular and damage-free blocks as possible, this is different from the mining of other mines that only obtain raw materials (regardless of the size and degree of fragmentation of the raw materials), which makes stone mining machinery both necessary. To protect the ore body, it is also necessary to protect the blocks; it is necessary to have both output and quality; it is necessary to consider both the current mining and future mining; it is necessary to consider not only the characteristics of the stone, but also the completeness and combination of machinery sex, efficiency. This makes it necessary to do mine planning and mining design before the stone is mined.
At present, there are usually 6 combinations of mechanical mining of decorative stone: hand-held rock drill to drill holes, combined with detonating cord and pyrotechnic materials; flame cutting machine combined with hand-held rock drill to drill holes, combined with detonating cord and pyrotechnics Fire rock drilling mining method of materials; diamond beaded wire saw with hand-held rock drill to drill holes, combined with detonating rope artificial rock drilling beaded saw mining method; diamond wire saw full sawing mining method; disc saw block stone cutter and diamond The mining method of the circular saw combined with the beaded wire saw and the beaded wire saw; the mining method of the beaded wire saw combined with the bench-type rock drill, and the bench-mounted rock drill and the beaded wire saw with the detonating cord.
Mining enterprises should choose an appropriate mining combination method according to various factors such as mining cost, block rate, variety characteristics, and market price. In fact, it is not necessarily better that the machinery is advanced and modernized. It should be the cost, waste rate, selling price, variety characteristics, environmental requirements and sustainable production that are suitable for the enterprise. However, the above six mining methods have their own advantages and disadvantages. Among them, the use of diamond beaded wire saws has a high rate of blockage, and is suitable for varieties with many fissures, unique colors, high market prices, utilization of resources, and environmental protection. Therefore, to a certain extent, the use of diamond beaded wire saws is one of the development directions of stone mining. Now in the stone kingdom of Italy, because of the mine design and management, some good stone mines have been mined for hundreds of years and are still serving human beings; although some can no longer be mined, they have been developed into characteristic tourism Scenic spots or storage facilities, or through landfills, replant trees and grasses to form green vegetation, which has become today's stone cultural landscape.
