Jan 01 2020nbsp018332Most coal exploration begins before any mining actually takes place The most common method to accomplish this is by drilling coreholes It is not uncommon for coreholes to be drilled just to obtain coal thickness and quality information describing moisture sulfur and ash contents along with other useful information to determine the value

Oct 01 2019nbsp018332Usually 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

Coal is mined by both surface or opencut or opencast and underground or deep mining methods depending on the local geology of the deposit Underground mining currently accounts for about 60 per cent of world coal production but around 80 per cent of Australias coal is produced from opencut mines
