# Key Machines Used in Modern Mining Operations

The mining industry relies on a variety of specialized machines to extract minerals, metals, and other valuable resources efficiently and safely. These machines enhance productivity while minimizing environmental impact and worker hazards. Below are some of the most critical machines used in mining today.

## 1. Excavators
Excavators are essential for digging and removing overburden (waste material) to access mineral deposits. Large hydraulic excavators, such as the Komatsu PC8000 or Caterpillar 6090 FS, can move massive amounts of rock and soil with precision.

## 2. Haul Trucks
Mining haul trucks transport extracted materials from the pit to processing plants or waste dumps. Some of the largest models include:
- Caterpillar 797F (Payload: 400 tons)
- BelAZ 75710 (Payload: 450 tons – one of the world’s biggest dump trucks)

## 3. Draglines
Draglines are enormous machines used in surface mining to remove overburden efficiently. The Bucyrus RH400, one of the largest draglines ever built, has a bucket capacity exceeding 90 cubic meters.

## 4. Continuous Miners
Used primarily in underground coal mining, continuous miners cut and load coal simultaneously. Examples include the Joy 14CM Series, which enhances safety by reducing blasting needs.

## 5. Longwall Miners
Longwall mining systems automate coal extraction using shearers like the Eickhoff SL900. These machines move along a track while hydraulic roof supports prevent collapses.

## 6. Drilling Rigs
Drilling rigs create blast holes or exploration boreholes:
- Rotary drills (Sandvik DR412i) for hard rock
- Blasthole drills (Atlas Copco Pit Viper) for open-pit mines

## 7. Load-Haul-Dump (LHD) Vehicles
LHDs transport ore in underground mines efficiently, with models like the Sandvik LH621 offering high payload capacities (up to 22 tons).

## 8.Crushing & Grinding Equipment
After extraction, materials must be processed using crushers (Metso Lokotrack LT200) and grinding mills (FLSmidth
