Drilling Machinery in Mining Industry
In the mining industry, drilling machinery serves multiple important functions.
One of the primary uses of drilling machinery in mining is for exploration. Just like in the oil and gas industry, exploration drilling helps to determine the location and quality of mineral deposits. Rotary drilling rigs are commonly used to drill holes in the ground. Geologists analyze the samples taken from these holes to assess the presence and quantity of valuable minerals such as gold, copper, and iron. Core – type diamond bits are often preferred as they can provide continuous core samples, which are crucial for accurate mineralogical analysis.
Once a mineral deposit is identified, production drilling begins. In open – pit mining, large – scale drilling machinery is used to drill blast holes. These holes are then filled with explosives to break up the rock containing the minerals. Percussion drilling machines are often used for this purpose as they can quickly and effectively drill holes in hard rock formations. The holes are drilled in a specific pattern to ensure efficient blasting and to maximize the recovery of the minerals.
In underground mining, drilling machinery is used for various tasks. It is used to drill holes for installing support structures such as bolts and anchors to secure the mine tunnels. Rotary drills are suitable for this type of work as they can drill holes at different angles. Drilling machinery is also used to drill ventilation holes to ensure proper air circulation in the underground mine. These holes help to remove harmful gases and provide fresh air for the miners.
Overall, drilling machinery is essential for the exploration, production, and safety in the mining industry.
