"Airborne heavyduty mechanical arm" is defined as a heavyduty mechanical arm installed on a piece of coal mine machine. The coal mine machine is a highvoltage (1140 V/50 Hz) machine which uses hydraulic power to drive its mechanical arm. The coal mine machine can be a mining drill jumbo, a roof bolter, and a road header.

Mining. Coal is extracted by two principal methods, of which there are many variants: surface mining or subsurface mining. Surface mining uses large machines to remove the soil and layers of rock known as overburden to expose coal seams that are close to the Earth's surface (figure (PageIndex{a})).Strip mining is a type of surface mining in which overburden is sequentially removed from ...
Underground mining, sometimes called deep mining, is a process that retrieves coal from deep below the Earth's surface—sometimes as far as 300 meters (1,000 feet). Miners travel by elevator down a mine shaft to reach the depths of the mine, and operate heavy machinery that extracts the coal and moves it above ground.

Hydraulic Excavators are heavy construction equipment consisting of a boom, dipper or stick, bucket and cab on a rotating platform. The house sits atop an undercarriage with tracks or wheels. They are a natural progression from the steam shovels and often mistakenly called power shovels. All movement and functions of a hydraulic excavator are ...
Coal mines operated without electricity. Electricity began to be adopted in mining and manufacturing in the late 1880s and the 1890s. (Electricity was first introduced into Ohio's bituminous coal mines in 1889.) The introduction of electricity in coal mines greatly facilitated the introduction of laborsaving machinery. 1891.

Mining Drills. Drilling equipment is perhaps the most commonly used in mining activities, specifically underground mining operations. They are used to drill and loosen the mineral ore for easy transportation to the surface. Miners widely use them because they reduce the number of people working in the mines and are also costeffective to use.
