Longwall shearers The coal is cut from the coal face by a machine called the shearer (power loader). This machine can weigh 75120 tonnes typically and comprises a main body, housing the electrical functions, the tractive motive units to move the shearer along the coalface and pumping units (to power both hydraulic and water functions).
Mines are carried out with different types of mining equipment. Mine equipment can be classified into above or belowground types depending on whether it is for gold, metals, coal, or crude oil mining. We have mining equipment's like drilling machines, excavators, dump trucks, road header and many more that are used in the mining industry. 3
The implementation of novel systems and adoption of improvised equipment in mines help mining companies in two important ways: enhanced mine productivity and improved worker safety. There is a substantial need for adoption of stateoftheart automation technologies in the mines to ensure the safety and to protect health of mine workers. With the advent of new autonomous equipment used in the ...

Monorails (Man riding car system) used for materials transportation and man riding. It is installed in roadways upto 3 km long and on gradients upto 450 (1:1). A minimum height of the roadway of 1500 mm. Materials upto the weight of 3 t/unit load can be transported. 138.
2. Coal winning • winning of coal by coal cutting machines, continuous miners or pneumatic picks produces a lot of dust. Dust produced by pneumatic picks can be reduced by about 50% by using wet pneumatic picks. Suppression of dust produced by coal cutting machines is usually done by water sprays incorporated in the machine.
Accurate numbers are more difficult to find in a global context, but some sources estimate that up to 12,000 miners die each year in mining accidents, mostly in coal mines.
A semicontinuous process system consisting of a singlebucket excavator, truck, crushing station, and belt conveyor is the main coal mining process system of a largescale hard coal openpit mine ...
3. To estimate normative productivity of shovel dumper combination with different material characteristic and different equipment combination. To validate the normative productivity with the actual productivity of similar equipment combination in certain selected coal mine. To analyse the reasons for variation between normal and actual productivity in different cases. To give suggestion for ...

Mine locomotive ppt (under ground transport system ) by AMIT SAHU ... INTRODUCTION : Continuous mineris a machine used for cutting and loading of coal used in underground Board and Pillar mining operation. The JOY continuous minerproduct line has been developed to meet the high productivity requirements of today's underground mining industry. 3.
The Ministry of Coal have desired to implement a smart coal logistics system, that aids in the planning of new projects, debottlenecking of existing infrastructure and assets, and facilitate realtime decisionmaking for smooth operation of coal supply chain. Our Approach for the Preparation of the Report There are two important events in play:
1. CONCEPT OF OC MINE PLANNING DESIGN. 2. Mining Methods • Coal is mined by two main methods Surface or 'opencast' mining and underground mining. • The choice of method is largely determined by the depth,thickness and no. of coal seams, geology of the coal deposit and other factors. 3.
Although the United States has the vast coal resource described in the previous chapter, perhaps as much as 4 trillion tons, the key issue for policy makers is the amount of coal that is economically is not a fixed quantity, but depends on the geological resource, the market price, and the cost of mining. The particular characteristics of the coal mining industry create unique ...
ffA mine railway (or mine railroad, ), sometimes pit railway, is a. railway constructed to carry materials and workers in and out of a mine. [1] Materials transported typically include ore, coal and overburden (also called. variously spoils, waste, slack, culm, [2] and tilings; all meaning waste rock). It.
