SURFACE ACCESS BOREHOLE RESOURCE

10/11/2016· Access hole N+2 has a region in deck 3 which is hypothesized to be sub-economic, so the exemplary method can focus nozzle induced disaggregation in this area and production ore can be analyzed on surface to confirm if the region is economic or not to mine and if mining can continue. Access hole N+6 did not meet minimum criteria of mass of mineralization, and thus no access hole

Surface and borehole microseismic monitoring

To determine whether 130 felt earth tremors around Edwinstowe, Nottinghamshire, UK, which also experienced severe surface fissuring, were caused by coal extraction, a surface seismometer array was established around Thoresby Colliery. Over the next year, 785 microseismic events were detected. The spatial and temporal variations in seismicity are clearly associated with the commencement
