The CMM2 series hydraulic anchor drilling rig for coal mines is an efficient, mechanized, and fast support equipment. The drilling vehicle adopts a dual arm drill and an overall lifting platform in the structure, and the platform lifting height can be adjusted according to the height of the tunnel, so as to easily achieve mechanized construction of anchor (cable) holes, blast holes, and detection holes at different heights and angles in the tunnel. At the same time, it can achieve simultaneous operation of the top and bottom, and complete the drilling construction of the entire section with one positioning, greatly shortening the support operation time and improving the support efficiency. It is currently the preferred equipment for fast, efficient, and mechanized tunnel excavation support in China, which can efficiently complete the supporting operation of the top plate support. It is mainly used in mines with explosive dangerous gases (methane) and coal dust.
