Prediction of gas emission on short faces and drivages
The influences of face length, face height, depth and strata strength on the size of the disturbed zone around short and longwall workings have been determined. Data have been acquired largely from the Selby coalfield. Additional corroborative data have been drawn from previous trials in other coalfields. Results obtained from the monitoring of two headings are presented.
