EMAS well drilling, Part 1 of 2
March 62010
EMAS well drilling is a method for drilling small-diameter tube wells by hand, up to 100 m deep. The drilling method is a hybrid between washboring, percussion and rotary drilling. It permits to drill through all kinds of loose soils, as well as consolidated materials and light rock. It will not, however, penetrate hard original rock or boulders (e.g. ancient river beds underground). The usual diameter of the tube well is 37 mm.

depends on the size. The drill bit you use has small holes in it, through which small gravel can pass (say, up to 1cm size). Due to the design of the drill bit, larger stones, say up to 2 cm can be smashed or pushed aside. Larger rocks are a real problem: you can cannot get past those with this technique. Other possibilies include the stone hammer technique (look on the akvopedia website), or machine drilling.
