Abstract
The objectives of this investigation were as fallows: - to use microseismic energy generated by rock fracturing to map the caving height and fracture architecture above a Longwall coalface. - to determine the spatial and temporal relationships between the fractures delineated by the microearthquake hypocentres and mining activity and roof control, particularly weighting on the face, - to investigate geological controls on the location of seismicity, - to attempt to determine the nature of the fractures forming above the extracted panel and assess their significance for roof control and water percolation from overlying aquifers. The site chosen for this investigation was Asforby, panel 101 because of the lack of previous mining, complex geology and the overlying Sherwood Sandstone aquifer.
