摘　　要：综采工作面液压支架降柱移架产生的粉尘极大地威胁着矿工的身心健康。创新性设计了一种液压支架侧护板落尘导移装置,通过液压油缸实现该装置的自动伸缩。通过现场试验,该装置表现出较好的降尘效果,最大降尘效果率达95.28%,有效解决了支架降柱移架产生的粉尘对矿工活动区的污染。The dust generated by the column lowering and moving of the hydraulic support in the fully mechanized mining face greatly threatens the physical and mental health of the miners. An innovative design of falling dust guide device for the side guards of hydraulic support was carried out, which realizes the automatic expansion and contraction of the device through a hydraulic cylinder. Through the field test, the device has shown a good dust reduction effect with a maximum dust reduction efficiency of 95.28%. It effectively solves the pollution of the miners activity area by the dust generated by the lowering of column and the moving of support.
