Drill and Blast Method. Drill and blast method is mostly used method for the excavation throughout the world. The method can be used in all types of rocks and the initial cost is lower than the mechanical method like TBM. This tunneling method involves the use of explosives.
Mar 13, 2012· (1) Drill AdaptabilityThe type of rock drill used in mining drilling is generally determined by the hole diameter required and the mechanical properties, principally hardness, of the top hammer is commonly employed for drilling of holes less than 125 mm in diameter in all but the hardest rock, although a rotary cutting method may instead ...
Drills used on wood or metal have a sharp metal tip or teeth, that cut into the material. These types of drills do not work on glass, marble, etc. as the tips do not "bite" into the extremely hard material, and cause heat buildup that burns up the bit and causes "heat fractures" in the material.
The underground mining methods we use include room and pillar, narrow vein stoping and largescale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.
Feb 22, 2012· Large mud pits are required. 4. Some drill sites are inaccessible because of the rig size. 5. For efficient operation, more personnel are generally required than for other drilling air rotary drilling (down the hole hammer drillingdiscussed in separate section)In air rotary drilling, air alone lifts the cuttings from theborehole.
Each of the models is developed from first principles based on typical mining criteria for rock densities, swell factors, drill penetration rates, etc. Industrystandard estimating methods are used for equipment selection, personnel allocation, and cost estimation. These models are invaluable for early order ofmagnitude estimates.
Application of Mining used cone crusher / marble mining equipment The machine is widely used for secondary and fine crushing in the fields of mining, building materials, metallurgy and so on. It can crush materials with middle and high hardness such as ironstone, copper ore, granite, basalt, cobblestone, marble, limestone and so on.
A common method for calculating this relationship is: d (inches) < H/5 (in feet). Thus, for example, the maximum recommended drillhole diameter for a mine that plans to develop a 60foot bench would be 60/5 or up to 12 inches. From the chart, the range will be to
