Abstract: One of the conditions for ensuring the safety of mining operations at the mine «Yerunakovskaya-VIII» is the isolated removal of the methane-air mixture from the goaf. To do this, linkages are drilled from the prepared airway for the next semilongwall face into the belt entry of the active face. Drilling of linkages is carried out by reaming the hole of the pilot drill hole with ABG-300 and BGA2M machines from 76 mm to 900 mm diameter, then the hole is lined with 800 mm diameter casing pipes. The whole process takes 5-7 days per linkage, taking into account the time for casing. In addition to long terms, the disadvantage is the possibility of destruction of the hole before casing. To eliminate these negative factors, it is necessary to create a drilling rig capable of drilling the whole required diameter in one pass, the pilot drill hole is not considered, as well as to carry out simultaneous casing of the hole. At the same time, the overall dimensions and weight of the drilling rig should ensure its transportability and placement in conditions of limited mining space.
