Technical Parameters of Pneumatic Pillar Drill Rig Specifications and Models of Pneumatic Pillar Drill Rig Instructions of Pneumatic Pillar Drill Rig The company's products are all available. Purpose and scope of use of pneumatic column drilling rig
This machine is mainly used in coal mines to drill gas drainage holes in coal seams
Working head gas drainage holes, water exploration holes, communication holes, cable holes and other engineering holes.
Main Features
This machine is powered by compressed air and is used in tunnels with compressed air. This machine does not have any electrical components
completely eliminating various safety hazards caused by electrical appliances. Therefore, it is particularly suitable for use in mines with coal and gas outbursts.
This machine is simple to operate and can be operated and transported by only urban residents in narrow tunnel space
It has particular advantages and is especially suitable for small and medium-sized local mines.
The drilling tools used in this machine are standard drill pipes and drill bits developed and produced by our company.
This machine has an all-metal mechanical structure and is very convenient for maintenance. It is very practical for mines with poor mechanical processing methods and insufficient technical strength.
