煤矿综采放顶煤工作面高浓度粉尘的综合防治

Preliminary Analysis on Comprehensive Prevention and Control of High Concentration Dust in Full-mechanized Caving Mining Face of Coal Mine

目前厚煤层开采中大多采用综采放顶煤这种方式,这种方式的优势明显,能够使得煤产量提高、产煤的效率提高、减少耗能,然而也存在一些弊端,煤矿综采放顶煤工作面的开采强度比较大,致使产尘的尘源就会比较多,进而粉尘的浓度也会很高,所以这就增大了相关工作人员对粉尘进行防治工作的难度。因此,本文阐述了防治综采放顶煤工作面高浓度粉尘的总体思路,提出了具体的防治措施,为煤矿的开采中提供了有效的参考。

One of the coal mining methods currently used is full-mechanized caving coal.This method has obvious advantages.It can improve the coal output,increase the efficiency of coal production and reduce energy consumption.However,there are also some drawbacks.The mining intensity of the top coal caving face is relatively large,resulting in more dust sources,and the dust concentration will be very high.This will increase the difficulty for the relevant staff to control the dust.Therefore,this article elaborated the general idea of preventing high concentration dust in fully mechanized top coal caving face,and put forward specific prevention and control measures to provide an effective reference for coal mining in future mining.
