Coal Mining Quickwrite

The three types of subsurface coal mining are conventional board and pillar mining, blasting gallery technology, and long wall mining.
Furthermore, the four steps of conventional mining include: drilling, blasting, lifting, and loading.
Drilling(first step)- The miners drill to make a hole in the rock where the explosives could be placed into the hole that is created after drilling into the hole.
Blasting(second step)- The miners later blast or explodes the explosives that is in the hole that was created after drilling because the main purpose of blasting is to loosen or soften the coal and the earth surface or land around it due to the fact that the coal could be later transported for processing purposes.
Lifting(third step)- The softened or loosened coal is later lifted onto tubs by the miners.
Loading(fourth step)- The tubs are later loaded onto the railroad tracks by the miners due to the fact that the railroad tracks will be used as a means to transport the coal on one place to another.
