[Dust control in Belgian coal mines. Status at the beginning of the year 1977].
The present communication gives a general view of the methods of dust control in the Belgian coal mines at the beginning of 1977. The statistical data received from the mines are presented in tabular form. The length and the output of coal faces treated by the classical methods of pre-spraying of the wall, wet cutting, water infusion and wet pneumatic picks, are given separately; in some cases two or more of these technics are used together on the same coal face. The number of hard headings in which different methods of dust suppression are used, is also given.
