Coal miners method depends on:
* Local geological conditions such as the nature of the rock cover, rock and coal floor geological structure.
* The situation of coal layers and form deposits.
Basically there are two ways of mining coal:
a. Open mine, done first by peeling the cover soil. At this time mining method which will be used is selected and the possibility of not having equipment problems. The existing equipment is modified so that the function can be double. Keep in mind also that different types of coal type and require different equipment. The machines have a modern mines can be used to work with a range of mining work broader and able to perform various jobs without the need to be changes or major modifications.
b. Underground mining, first performed by making a hole in the form of hole preparation sinks or a flat or declining holes into layers of coal to be mined. Further holes opening in the layer of coal itself.
How to mining can be done:
a) In the manual, which is using many tools that use the power of human energy.
b) The mechanical, it use a simple tool to use the electronic system with remote control.
