In-seam drilling has two main purposes: gas drainage and exploration. Each hole can yield information on the geological structure of the ground drilled, but in the drilling of some gas drainage holes, valuable geological data is lost. Drilling technology has changed in some ways over the last ten years, but still has some way to go. There is room for more improvements to reduce the costs, to reduce the risks and to increase the information gathered.
