1. Introduction Dump trucks are used worldwide for handling of ore and waste in most of the opencast mines. It is considered as one of the versatile heavy earth moving equipment. The diesel consumption in dump trucks accounts for about 56 % of the total diesel consumption in opencast mine [1].
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.

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.
The deployment of this innovative machinery demonstrates WCL and Coal India's commitment to update and optimize mining methods while increasing efficiency and safety. The addition of these heavy earth moving machines (HEMMs) is expected to give the ontheground workers a distinct advantage, allowing them to maximize output and easily meet ...
The whole body vibration of heavy earth moving machinery operators in Indian surface mines were measured with regard to seatsurface and seatback using a triaxial accelerometer. The obtained results were evaluated based on guidelines as stipulated by ISO26311:1997 and EU 2002 Directive. The following conclusions were drawn from the analysis ...
Stateowned mining giant Coal India (CIL) imports equipment including continuous miners equipment, crawler dozers, drills, dumpers, electric rope shovels, frontend loaders wheel dozers, hydraulic shovels and motor graders.. CIL incurs Rs35bn () on the imports and an additional Rs10bn is paid as customs duty. Hence, a plan has been proposed to phase out its imports in the next fiveto ...
