煤炭生产过程中,所有环节和工序都会产生粉尘,因而煤矿井下的尘源分布很广.各种尘源的产尘量,由于受矿井地质、开采技术、煤的性质及是否采取防尘措施等诸因素的影响,各矿、采区或煤层之间都会有很大差异.因此,本文只能通过对一些数据的分析对比,对各种尘源作一基本介绍,进而探索浮游粉尘在煤矿井下分布的一些现律.一、井下尘源以下作业地点都是井下的尘源:打眼、爆破、采掘机械割煤(岩)或风镐落煤、装载和卸载、运输、转载、移架、放顶、采空区充填、锚喷支护、巷道撒布岩粉、箕斗或矿车提煤(岩)等. Coal production process, all links and processes will produce dust, so coal mine dust distribution is very wide.Dust of dust produced by various sources, due to mine geology, mining technology, the nature of the coal and whether to take measures such as dust control Therefore, this article can only make a basic introduction to various dust sources by analyzing and comparing some of the data, and then explore the effect of the floating dust in the coal mine Distribution of some current law.A underground dust source The following operations are dust underground sources: drilling, blasting, mining machinery cutting coal (rock) or blast off coal, loading and unloading, transportation, reprinting, moving rack, put Top, goaf filling, anchor spray support, roadway spreading rock powder, skip or car mention coal (rock) and so on.
