Detection of areas with a rockburst hazard on the basis of deposit conditions
36A design and the marriage of the soft ground slurry shield and the hard rock tunnelling machine are expected. The potential for automation of the tunnelling process, despite the hostile underground environment, and the problems of shaft sinking are briefly discussed. 861287 Construction of the 'Westtangente' motorway tunnel in Bochum under extremely difficult environmental conditions Steinheuser, G; Maidl, B
Proc of the Eurotannel '83 Conference, Basle, 22-24 June 1983 P29-33. Publ Marlow: Access Conferences Ltd, 1983 The tunnels under construction are under a densely built-up residential and business area. Details of the following are discussed: geological and environmental conditions; planning authority and special proposals; the top cover method in the entrance areas and driving of a pilot gallery with the MiniFull-Facer; failure of the Mini-Full-Facer; changing of the special proposal to top heading and excavation in partial section using the New Austrian Tunnelling Method; execution of the construction work; and blasting work in a built-up area, drilling pattern, length of rounds and ground support methods. 861288 Performance of a full-face tunnelling machine in Coal Measures strata Snowdon, R A; Glossop, N H; Farmer, I W

Gluckanf V121, N14, 25 July 1985, P1069-1075 (german). P322-326 (english) Data from 424 rock bursts in the Ruhr coalfield, West Germany, have been computer analysed in an attempt to determine common factors which may be used to predict areas of rock burst hazard. Mine and seam geometries, properties of the seam and adjacent rock, rock pressure and direction of working were considered. The most commonly found features accompanying rock burst were: (1) seams of high strength or with dirt bands; (2) residual pillars or working boundaries; (3) drivage next to an adjacent panel in the same seam; (4) mine workings, the goaf or a fault in the same seam were approached; or (5) a solid rock bed was formed in the seam floor. 861293 Pressure measurements in the gob Maleki, H; Hustrulid, W; Johnson, D

Pressure measurements in backfill materials were made as part of a program to evaluate cave progress and examine the effects of geological structure on caving, load transfer and resulting instabilities. Gloetzl cells were used, due to their robustness and ability to monitor the pressures in a broken medium. Results indicated that cave progress was controlled by frequency of major faults.
The construction methods for the tunnels and stations of the Pre-Metro works in Antwerp, Belgium, are described. For the tunnels, slurry-shield tunnelling is used, and for the stations pipe jacking. The execution and construction technique is examined in detail.
