رودهدرهای ياسيناواتسکی PK-8MA - زاگرس ماشین
KThe PK-8MA heading machine is designed for driving development workings and extraction chambers in underground potash ore mines where cutting resistance may vary from 4.0 to 4.5 kN/cm2 and rock breaking point up to 60 MPa. The machine breaks rock in the face, clears the face from the rock and loads it into mine cars. The cutting tool of a rotary type has 2 drills (external four-beam drill with cups and internal double-beam drill with starting borers) rotating in different directions. The machine has a mounted drill rig for drilling methane drainage boreholes. Smooth control of the working feed provides optimal performance of the drills in faces with the different ultimate strength of rocks. The machine has a combined system of dust suppression consisting of dust evacuation and water spray subsystems. The heading machine has semi-automatic and manual modes of control. The control mode depends on mining, geological and technical conditions in which the heading machine is to be employed.
