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.
本通讯概述了1977年初比利时煤矿的降尘方法。从各煤矿收到的统计数据以表格形式列出。分别给出了采用壁面预喷雾、湿式切割、注水和湿式风镐等传统方法处理的采煤工作面的长度和产量；在某些情况下，同一采煤工作面会同时使用两种或更多种这些技术。还给出了采用不同降尘方法的硬岩巷道数量。
