矿山平巷掘进过去一直采用压风清除炮眼岩浆,吹出的岩浆四处飞溅,充满整个工作面,劳动条件很差。我矿在推广江西下垄钨矿吹眼除尘器的过程中,作了改进,试制成现在使用的炮眼冲洗器(图1、2)。经一年多的实践证明,它具有结构简单、使用方便、降尘效果好等优点,深受凿岩工人欢迎。使用炮眼冲洗器之后,经测定,粉尘浓度由53毫克/米~3降至0.2毫克/米~3。
In the past, mine lanes had been used to remove blasthole magma by pressure air blasting. The lava was splashed around and filled the entire face, causing poor working conditions. My mine in the promotion of Jiangxi under the tungsten mine tungsten dust collector in the process, made improvements to try out the now used borer (Figure 1, 2). After more than a year of practice has proved that it has the advantages of simple structure, easy to use, good dust effect, deeply welcomed by the rock drilling workers. After using the blasthole washer, the dust concentration was reduced from 53 mg / m 3 to 0.2 mg / m 3.
