There are two main types of core drilling: hard coring and soft coring. This refers to the type of lithology each method is suited for. Soft coring is used when taking a core sample of unconsolidated material and is capable of reaching depths of 500 feet (or more—but this is what is typical for environmental industry projects).

The process begins by drilling a hole deep into the earth. To do this, a long bit attached to a "drilling string" is used. The bit varies in diameter from five to 50 inches. After each section is drilled, a steel pipe slightly smaller than the hole diameter is dropped in and often cement is used to fill the gap.

Water inflow was a very important problem in underground mining until James Watt invented the steam engine in the 18th century. After that, steam-driven pumps could be used to remove water from the deep mines of the day. Early lighting systems were of the open-flame type, consisting of candles or oil-wick lamps. In the latter type, coal …

The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.
