The UBSH-210A crawler mounted mine drilling rig with one boring machine of rotational type having an electric drill bit is designed for short-hole drilling in shaly and coal mines including gas-and dust-hazardous mines. The use of the rig in seams prone to sudden outbursts is prohibited.

Three versions of UBSH210A are available: UBSH210A, UBSH210A-03 (with shortcut feed) for drilling of face bore holes in chambers and longwalls of shaly mines in rocks where hardness is f= 2-4 and UBSH10A-02 for drilling of bore holes when driving of horizontal and inclined up to±12° development workings in coal; mines in rocks with strength of up to fЈ8.
