在采矿工业生产过程中,每个工序都产生矿尘。为了防止矿尘危害人体健康和影响安全生产,必须采取湿式凿岩、喷雾洒水和洗巷道壁等综合防尘措施。但仍有一部分微细矿尘浮游于井下空气中,必须用通风的办法稀释和排除。通风是现代技术条件下最重要和最有效的防尘手段之一. 迄今为止,巷道型采场排尘通风所需的 In the mining industry, mine dust is generated in each process. In order to prevent mine dust from damaging human health and affecting safe production, it is necessary to adopt comprehensive dust control measures such as wet rock drilling, spray sprinkling and roadway cleaning. However, there are still some fine dust floating in the underground air, it must be diluted with ventilation and eliminate. Ventilation is one of the most important and effective means of dust control under modern technical conditions. So far, the required ventilation and drainage of mine roadway stope
