MILE MINING METHOD Mile mining is broke and transport of rock salts, which have been embedded with tectonic changes for thousands of years, using room and column system in traditional mining. It is also called as "Shaft Mining". Rock salt mines can be in depths between 100 meters and 500 meters. Shafts to break rock salt are embedded in the bottom of mine and drilling, cutting and blasting ...

contact usMining3 developed the Oscillating Disc Cutter, which was licensed in 2006 by Joy Global (now Mining Corp) and rebranded as DynaCut™. With relatively low input power, the DynaCut cutting technology – now incorporated into ''s DynaMiner machine – enables continuous, or semi-continuous mining of hard rock in both surface and underground applications.
contact usThe Continuous Mining Process Typically, to begin a room, the continuous miner engages in cutting (removal) a 3 m (9.8 ft) wide sec-hon of coal to a depth determined to be safe based on local geologic conditions and mining regula tions-on average up to 6.1 m. Deeper cuts can be made (called extended-cut mining) with special per
contact usA. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

contact usThis grout is designed to secure rock and cable bolts in tunnel and mine applications. It quickly develops a thixotropic characteristic that minimizes free flow but allows continuous, as well as interrupted, pumping overhead.
contact usThe continuous mining method means that your project can keep a steady pace without interruptions and maintain the productivity at a fixed and stable level. This facilitates planning and scheduling. Additionally, safety is increased a great deal with cleaner air and a much lower risk for falling rocks -a safer work environment for everyone.
contact usThe continuous mining process uses a machine to cut rock away from the mine face. It''s simpler, takes less mining equipment, less underground transportation machinery and less manpower than the drill-and-blast process that it replaces, and reduces fuel use and emissions.
contact us· engineers envision the new cutting technology will be used in a number of different types of hard rock mining systems: "For example, a compact and versatile unit could cut and load hard rock in a continuous, automated process. Such a system would enable high-speed mine development and faster access to ore deposits.

contact usMore modern room and pillar mines use a more "continuous" method, that uses machinery to simultaneously grind off rock and move it to the surface. Other processes, such as backfill, where discarded tailings are unloaded into mined-out areas, can be used, but are not required. Retreat mining (below) is an example of a process like this.
