Latest Experience with Dust Suppression in Tunnelling

The necessity of effective dust suppression measures during excavation work is just as uncontroversial in tunnelling as it is in mining. In many respects, in fact, the applied technology is comparable. Notwith- standing, given more careful appraisal, it becomes evident that very different starting conditions exist in both these fields: In mining, there are for instance, well organised firms, which in many cases have been active for several decades, carrying out the required drivage and winning operations - and although there are also experienced firms in tunnelling, these generally speaking form a joint venture in order to accomplish a certain project. These "tunnelling firms" which are formed for a short term, normally only exist for a period of two-to three years. They con- stantly reorganise themselves: from the site supervising engineers by way of the foremen and shift overseers to the gangs working on site. The "firm's headquarters" are also re- located when a new project is started up. Then of course, there is often pronounced fluctua- tion among the crews of a single tunnelling project. Seen from this point of view, a safety expert in tunnelling has a far more difficult task than one in mining. He has not the advantage of knowing every corner of the mine for years if not decades on end, of being familiar with the overall organisation of the enterprise let alone knowing many of the men at the face. This ideal prerequisite for effec- tive decisions pertaining to suitable measures for industrial safety and accident prevention taking all weaknesses into consideration given the interplay of the most varied system com- ponents, can practically only be arrived at in mining.
