Fixed type breaker is widely used in underground mines
When the ore deposit is deep below the surface, if open-pit mining is adopted, the stripping coefficient is very high, which is not conducive to the development of the mine. It is more economical and reasonable to adopt underground mining. The ore body is deep underground, and mining must be carried out from the surface to the ore body through tunnels, such as vertical shafts, inclined shafts, ramps, horizontal tunnels, etc. The focus of the basic construction of underground mines is to dig these shaft and tunnel projects.
Exploration, mining and recovery are the three steps of underground mining. Exploration is the tunneling project. Mining is the preparatory work for the recovery of ore on the basis of the development project, including the horizontal tunnels, horizontal tunnels and skylights in the excavation stage. Cutting is the shaft and tunnel project that must be completed before the recovery operation. Recovery is mining in the mining area, including rock drilling and caving ore, ore transportation and support of the mining area. These three steps are carried out in sequence at the beginning of mining. After the mine is put into production, various shafts and tunnels need to be excavated to maintain continuous normal production. Such as extending and developing tunnels, excavating various prospecting, mining, and recovery tunnels, etc.
In underground mining operations, large pieces of ore often cannot be crushed, and stone blockage will affect production efficiency. In order to solve this problem and improve productivity, fixed breaker hammers have been developed and have become an essential mechanical equipment in mining. Fixed breaker hammers adhere to the concept of building green, environmentally friendly, and digital mines. The motor drive is pollution-free, highly efficient, and safe. Fixed breaker hammers have been widely used to crush stones at the screen mouth of underground mines.
