The journal aims to advance the environmentally sustainable exploration and utilization of these resources, as well as advancement of engineering and technology for …

Usually in coal exploration drilling, the base of the cored interval is the base of a target coal bed, or just below the target coal bed. For continuous core drilling, the core from each core barrel may be laid out on the ground, described, and the sections sampled for analysis; the remaining core is then disposed of. In most cases, however ...

COAL EXPLORATION, MINE PLANNING, AND DEVELOPMENT "Coal in truth stands not beside but entirely above all other commodities. It is the material energy of the country-the uni· versal aid-the factor in everything we do. With coal almost any feat is possible or easy. Without it we are thrown back into the laborious poverty of early times."

Despite this favourable situation for geophysics, exploration for coal in many countries mainly relies on drilling. The main reason for this is that when compared to petroleum exploration, coal exploration is concerned with much shallower targets (typically less than 2–300 m for open pit mining and less than about 1000 m for …

Coal is a non-clastic sedimentary rock. They are the fossilized remains of plants and are in flammable black and brownish-black tones. Its main element is carbon, but it can also contain different elements such as hydrogen, sulfur and oxygen. Unlike coal minerals, it does not have a fixed chemical composition and crystal structure.
