As for magnesium chloride powder, some people know that it can be used as a food agent. In fact, magnesium chloride powder also has the role of coal mine dust collector.
It can be said that coal resources are indispensable resources in our lives. A large amount of dust is generated during coal mining. Some of the electricity is generated by thermal power, and a large part of thermal power comes from coal burning. When mining coal, coal dust not only affects the safety of miners' lives, but also causes an explosion if the concentration of pulverized coal is too high. No wonder coal dust is listed as one of the top five natural disasters in coal mines. It can be said that in coal mines, effective control of dust and reduction of dust concentration are the prerequisites for preventing coal mine accidents. The following is a method of applying a coal mine dust collector to magnesium chloride powder: First, coal seam water injection refers to the injection of water into the coal seam when the coal mine is mined, so that the coal seam loses the ability to remove dust. This can reduce the dust concentration by more than 60%-90%, but due to the huge water consumption, it is only suitable for large coal mining enterprises. Secondly, the addition of dust collector and magnesium chloride powder in the water can greatly improve the dust removal effect, and the dust removal effect can be increased to more than 96%. It is one of the dust collection methods used in coal mines in the world.
