Abstract: ZDY4000LF split type caterpillar drill was developed successfully according to the requirements of high-gas coal mine gas drainage drilling and construction characteristics. The drill has many advantages, such as small size, novel structure, complete function, simple operation, power maneuverability and suitable for gas control in high gas mine. The drill has a larger regulation range of elevation angle, the agimuth angle and drilling hight. Drilling techniques can be suitable for bedding holes and through beds holes.
