Abstract

This publication is the final report on a research project designed to address one of the principal geological problems which arise in the development of areas where there is little or no information available from previous workings. Effective mine planning requires the identification and avoidance of places where the target seam is disrupted by geological faulting to such an extent that production costs would be unacceptably high. When this project was conceived it was believed that much of the future United Kingdom (GB) deep-mine production would be from new areas where little or no fault information is available from previous or current workings. The seismic reflection method is used to obtain fault data such that the smallest fault throws (vertical offsets of a seam) which can be detected are 5 m or greater, whereas faults with throws as small as 1 m can hinder production and significantly increase costs of production. The limit of seismic resolution of fault throws varies with seam depth and other factors which affect the quality of the seismic data. The minimum size of fault which will hinder production varies with seam thickness and other considerations. The project was therefore directed towards development of a method of predicting, from surface seismic data, the numbers and positions of fault throws between 1 m and 5 m (plus).
