The technique is not suitable for effective sampling but is a quick procedure for probing the presence of old mine workings.
Combinations of techniques can be used, such as windowless sampling, as well as the rotary open hole technique, if suitably less disturbed samples are required from the upper strata. This can facilitate a number of investigations and assessments being carried out with one site visit rather than two or more.
In a coal mining area, before works are carried out, there will be a need to obtain permission from The Coal Authority. It should be noted that this can sometimes take up to 28 days for permissions to be obtained but they do offer an expedited service in which we will receive the permission within 2 weeks at an increased cost of 100%.
Our service provides the client with obtaining the licence, carrying out the site works and then providing a factual report.
