Recently, the anchor rod drill car independently developed by Shijiazhuang Coal Mining Machinery Company has been successfully rolled off the production line and will be sent to users immediately. The drill car has a novel design and strong practicability. The drill arm can drill 2.4 meters at a time without connecting the drill pipe. The drilling arm mechanism is flexible in displacement, fast and accurate in positioning, which can realize the efficient drilling of bolt (cable) holes with different heights and angles in the roadway, and can also carry out drilling on the roof and side at the same time, effectively meeting the operation requirements of fast drilling and installing bolt on the roof and side of low roadway in coal mine.
