摘要
煤巷掘进中由于破煤、装运等各工序会产生大量煤尘,严重影响煤矿安全生产和作业人员身体健康。通过分析金家庄煤矿北回风大巷掘进采用煤层注水防尘方法,探求煤层注水技术降低煤巷掘进过程中煤尘产生的浓度,为今后煤层注水降尘技术提供科学依据。
During coal roadway excavation,a large amount of coal dust is generated due to various processes such as coal breaking and shipping,which seriously affects the safety of coal mine production and the health of workers.This paper analyzes the use of coal seam water injection and dust prevention method in the excavation of the north return air roadway in Jinjiazhuang Coal Mine to explore the use of coal seam water injection technology to reduce the concentration of coal dust generated during the coal roadway excavation process,in order to provide scientific basis for future coal seam water injection and dust reduction technology.
