Key technologies of drilling process with raise boring method
In 1850, a percussion-type drilling machine was first used to drill a small diameter shaft. In the 1930s, the rotary rig was adopted for drilling vertical shafts, and the tunnel boring machine (TBM) was applied in tunneling gradually. In the 1950s, miners applied the rock-breaking mechanism of shaft drilling machines and TBMs to raise boringMining drill. Underground Loader. Crane lift. Shotcrete machine. Longwall Mining. Within the mining operations, the activity of management and management of machinery for minerals, affects the cost of operation in general, mainly due to the large amount and variability of resources involved in it.MINING Equipment List Mining Tools Names

CIVIL ENGINEERING Vol. II Drilling Machines H.Watanabe ©Encyclopedia of Life Support Systems (EOLSS) Figure 1: Three-cone bit With percussion drilling, the bit is driven into the rock by either a top hammer, in which case the drill rods transmit the impact of a blow at the surface, or a “down the hole drill”For medium-hard rocks, drilling machines are effective with an increase in feed of 800-1200 kg with a drill rotation speed of 200-500 min 1, a frequency of 3000-4000 impacts per minute with an impact energy of 3-5 kgm. When drilling hard rocks (f ≥ 14), the rotational speed of the drill should be reduced to 100-300 min 1.Analysis of efficiency of drilling equipment use in mining

Intelligent Mining Technology for an Underground Metal
The final features were multiple drill-pipe storage, automatic sorting, and anti-blocking resistance rod technology. Fig. 9 shows the operation of an intelligent DTH drilling machine. The characteristics of the DTH drill determine that if the hole is 60 m deep, then at least 40 drill pipes are needed every time.Depending on the model, the Self-Propelled Mining Machine can be used to drill shot holes or anchor holes. All its types and varieties have an identical complete tractor and a front platform (Fig. 1) and differ mainly in the work booms and their attachments.The new generation drilling machine's intended use is roof bolting or (after retooling and New generation automated drilling machine for tunnelling
