The present communication gives a general view of the methods of dust control in the Belgian coal mines at the beginning of 1979. 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 and water infusion are given separately; in some cases two or more of these technics are used together on the same coal face. The number of stone drivages in which different methods of dust control are used, is also given.
本通讯概述了1979年初比利时煤矿的粉尘控制方法。从煤矿收到的统计数据以表格形式呈现。分别列出了采用壁面预喷、湿式切割和注水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。还给出了采用不同粉尘控制方法的岩巷掘进数量。
