1. Purpose of NKR Drilling Rigs

Underground drilling rigs NKР100 are designed for drilling holes of any direction with a diameter of 85-150 mm and a depth of up to 80 m in rocks with a hardness coefficient of f=6-18 (according to the scale of Professor M.M. Protodyakonov) in areas with a temperate climate (for temperatures from -5 to +60 degrees) with a relative humidity of up to 95%.

 

2. Modifications of the NKR Drilling Rigs

NKR100MA – rig with electric drive, with 2 feeders;

NKR100MPA – rig with pneumatic drive, with 2 feeders;

NKR100MVA – rig with electric drive, with 4 feeders;

NKR100MVPA – rig with pneumatic drive, with 4 feeders.
