Abstract: The coal mine drilling rig in the dry drilling construction, will inevitably produce dust pollution. The wet dust removal system used in the mine is good, but the volume is large, the installation is more complex, and the effect of the dust suppression can be generally. Therefore, it is necessary to develop a dry dust removal system, which has a small size, good effect. It is necessary to solve the construction dust pollution and improve the construction environment. The new type of airborne dust removal system is developed on the base of the bottom board, which can improve the working environment and improve the operation efficiency.
