Preparation of ores and rocks includes perforation and blasting. Perforation blasting is to drill a blasting hole with a certain diameter and depth in the ore and rock of the open pit mine, and then fill it with explosives, and use the explosives for blasting.
Mining and loading is the core link of open-pit coal mine. Mining equipment is used to extract ores and rocks from whole or blasting piles and load them into transportation equipment or directly unload them to designated places.
Send the mined coal to crushing stations, coal storage kilns and other places; Send the stripped rock and soil to the garbage dump; Send the personnel, equipment and materials needed in the production process to the workplace.
