Research into the stability of restored opencast coal mine sites in the north east of England

ABSTRACT The paper presents an analysis of backfill settlement observations conducted at a number of opencast mine sites in the North-East of England. The work is aimed at developing a better understanding of the stability of the restored mine backfills from the point of view of structural development. The project is specifically concerned with the effect on fill movements of the re-establishment of groundwater regime on the completion of surface mining, in particular the occurrence of collapse settlements associated with groundwater recovery within the backfill mass.

Cohesive soil compaction by water jetting

This paper examines the water jetting method used to compact cohesive soils. In order to gain better understanding of the process associated with water jetting compaction, including the selection of jetting equipment and technique for carrying on this operation, the investigation includes both the theoretical and experimental aspects. Based on theoretical analysis of the hydraulics of water jetting, equations for calculating the compactive force applied by the water jet to the soil and the magnitude of applied jetting energy are derived and used to evaluate jetting performance in the field. Records of full scale field experiments are presented, showing the influence of the nozzle pressure, nozzle diameter, jetting time, and the jetting probe spacing on the backfill compaction and settlement. This study is supported by discussion of the present state in the art of water jetting and by records from jetting projects completed in the past. Keywords: water jetting, jet compaction, jetting energy, clay backfill, settlement, soil moisture.
