Masters ZDY-2300 hydraulic mine tunnel drilling focused on 300 meters of coal mine tunnel drilling ZDY-2300 hydraulic tunnel drilling rig tunnel 300 meters Features ZDY2300 type Mine is one of the series of hydraulic tunnel drilling rig ZDY I developed. The rig hydraulic drive mechanism, a large drilling capacity, fast, simple, stable and reliable, easy mobile installation while to resolve outstanding seam soft spray holes appear in the course of drilling, the collapse of the hole, sticking and other phenomena . Scope? ZDY2300 tunnel drilling rig is mainly used for coal mine gas extraction (row) to put hole, grouting fire hole, coal water holes, anti-conflict relief hole, holes, and other engineering geological exploration drilling.
