The machine must be capable of cutting its own entry into the stope and thus minimize the requirement for pre-development.
This equipment can normally have a second blade in front of the front axle and in some instances can be used for underground mining. They are normally used to fine grade dirt or gravel roads, or to prepare the base course before placing asphalt.
The two main types of mining are surface mining and underground mining. Mining is further divided into several other categories including room and pillar mining, slope mining, block caving, quarrying, open-pit mining and in situ mining.

In mining sector, these rock cutting tools are used to drill and extract metals and minerals but new technology such as rock blasting, water hydraulic rock drills, and vibration assisted tools are taking over.
Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the surface.
In general rocks are of three types, namely, igneous (Igneous Stone Cutting Blades), sedimentary (Sedimentary Stone Cutting Blades), and metamorphic (Metamorphic Stone Cutting Blades). These rock/stone types as well as artificial rock/stone (Artificial Stone Cutting Blades) are commonly used in construction as a building material for walls ...
Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an orebody, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

it to be removed with a conventional bit. These combined systems could yield a two- to fourfold increase in drilling rates ().A similar system could be used to speed up the advance rate of tunnel boring machines (TBMs; Figure 5.7).Cutting slots in the rock with a novel device weakens the rock and allows conventional cutters to break the rock into larger fragments ().
Granite is a common and widely occurring type of intrusive, felsic, igneous rock. Granites are usually medium to coarsely crystalline, occasionally with some individual crystals larger than the groundmass forming a rock known as porphyry.
Mining accidents occur in the process of mining metals or minerals. Thousands of miners die from mining accidents each year, especially in the process of coal mining and hard rock mining. Generally speaking, surface mining usually is less hazardous than underground mining.
