煤矿综采放顶煤工作面高浓度粉尘的综合防治

Comprehensive Control of High Dust Levels in Sublevel Mechanized Caving Coal Face

煤矿综采放顶煤工作面开采强度大、产尘尘源多、粉尘浓度高，因而对尘毒的治理难度大。为此，提出了治理的总体思路、防治方案并在几十个煤矿综采放顶煤工作面推广，取得了很好的效果。

Sublevel Mechanized caving method shows the characteristics of high out-put,more dust sources,high dust concentration and difficult to control.A brief introduction to the general route and protocol for dust control is given, which has been applied and verified in tens coal mines with success.
