挡风墙是利用空气动力学原理，按照实施现场环境风洞实验结果加工成一定几何形状、开孔率和不同孔形组合挡风抑尘墙，使流通的空气（强风）从外通过墙体时，在墙体内侧形成上、下干扰的气流以达到外侧强风，内侧弱风，外侧小风，内侧无风的效果，从而防止粉尘的飞扬。该技术目前在国内处于领先地位。挡风抑尘墙由独立基础、钢结构支撑、挡风板三部分组成。
According to the principle of aerodynamics and the results of the wind tunnel experiment, the windbreak wall is processed into a certain geometry, opening rate and a combination of different hole shapes to prevent wind and dust. When the air (strong wind) flows through the wall from the outside, the upper and lower interference airflow is formed inside the wall to achieve the effect of strong wind outside, weak wind inside, small wind outside and no wind inside, so as to prevent Stop the flying dust. At present, the technology is in the leading position in China. The wind and dust control wall is composed of independent foundation, steel structure support and wind shield.
料堆起尘分为两大类：一类是料堆场表面的静态起尘；另一类是在堆取料等过程中的动态起尘。前者主要与物料表面含水率、环境风速等关系密切，后者主要与作业落差，装卸强度等相关联。
There are two types of material heap dust: one is static dust on the surface of material yard; the other is dynamic dust in the process of stacking and reclaiming. The former is closely related to the surface moisture content of materials and environmental wind speed, while the latter is mainly related to the operation drop and loading and unloading strength.
对于散料堆场，只有外界风速达到一定强度，该风力使料堆表面颗粒产生的向上迁移的动力足以克服颗粒自身重力和颗粒之间的摩擦力以及其他阻碍颗粒迁移的外力时，颗粒就离开堆垛表面而扬起，此时的风速就称为起动风速。
For bulk storage yard, only when the external wind speed reaches a certain strength, the power of upward migration of particles on the surface of the pile caused by the wind force is enough to overcome the gravity of particles, the friction between particles and other external forces that hinder the migration of particles, the particles will leave the surface of the pile and lift up, and the wind speed at this time is called the starting wind speed.
