... of injection distance on the stimulated area has been studied. It seems that there is an effective injection distance beyond which rock mass response remains approximately constant. Applying hydraulic fracturing further from the effective distance would precondition the hard rock but it would take longer...

... Abstract For the extraction of medium hard rock cutting machines such as road headers, continuous miners or longwall shearers are often used. The defining parts of these machines are one or more rotary drums equipped with picks. While the picks are in interaction with the rock they emit a wide...
