Coal Shearer Cable

Mining & Tunnelling CablesLongwall Mining (Coal Shearer) Longwall mining is a form of underground mining where a long wall of coal is mined in a single slice (typically 0.6–7.0 m thick). The longwall panel (the block of coal that is being mined) is typically 3–4 km long and 250–400 m wide. The coal is cut from the coalface by a machine called the shearer.0.66/1.14kV and below fire-retardant coal mine shearer .0.66/1.14kV and below fire-retardant coal mine shearer rubber flexible cable Product description: The rated voltage of the mining rubber cable is 0.66/1.14kv or 0.38/0.66kv. 0.66/1.14kV and below fire-retardant coal mine shearer rubber flexible cable is copper core conductor ,It is a special cableNTSCGECWOEU Medium-Voltage Shearer Power CableThese shearer power cables are used in underground mines as well as in tunnels if monitoring of outer damages is required. The robust construction allows the cable to be used on mobile equipment, on energy lines, as well as for occasional reeling. NTSCGECWOEU Medium-Voltage Shearer Power CableMining Cable – Hi-Sea CableShovel/Shearer Cable:The cables are suitable for coal mining machine and similar equipment as power connecting cable.SHEARER – Mining Science and TechnologyThe coal shearer is the only type of power loader that is used in Australia. There are currently four manufacturer’s of shearers in Australian, these being : DBT, Joy Global, Eickhoff, Mitsui Miiki. A typical shearer can be as long as 15 m and weigh in excess of 90 tonnes.

Diffuse pollution characteristics of respirable dust in .May 20, 2018 · At this time, main mechanical & electric equipment such as coal shearer and cable groove have a minor turbulence effect on airflow. After the airflow encounters the coal shearer, most of the airflow bypasses the coal shearer and diffuse to the above zone and the driver side when the airflow encounters the coal shearer, which leads to the .US4753484A – Method for remote control of a coal shearer .The coal-rock interface sensor is a shielded resonant horizontal loop antenna.

The area of shear failure decreases, but this zone centered at the top corner of removal area and it is under the control of the cable. Then the shearer further advances, and the red shear failure zone gathers and expands upward and backward gradually.

CABLE-TYPES & SIZES – Mining Science and TechnologyFigure 1 above shows a selection of cable bolt types used in Australian underground coal mines. Most cable bolts used in Australian mines are of seven or 19 wire construction. The seven wire cables has six outer wires wrapped around the central core wire, which is known as centre or king wire.NSSHKCGEOEU Coal Cutter Cable 0.6/1KV – Hybird ResourcesThis NSSHKCGEOEU cable is used as a power supply connection cable for mobile equipment in underground machine applications, such as coal shearer, road header, TBM`s, or scoops (LHDs).
