Mining thin coal seams is both difficult and uneconomical. As a result, most thin-seam coal reserves in the United States are not being mined. It is estimated that nearly 910 gt of coal reserves exist in 355- to 710-mm-thick seams. The U.S. Bureau of Mines is attempting to develop new techniques for mining 150- to 1,065-mm- thick coal seams.

Coal is the main source of energy. In China and Vietnam, coal resources are very rich, but the exploration level is relatively low. This is mainly caused by the complicated geological structure, the low efficiency, the related damage, and other bad situations. To this end, we need to make use of some advanced technologies to guarantee the resource exploration is implemented smoothly and orderly.
