Drilling rigs on the construction of the Olovozavodsky bridge
Tracked carts
A drilling machine is a drilling machine installed on a self-propelled platform or mobile frame, used for drilling explosive and exploratory wells and blast- holes in open-pit and underground mining of minerals , with continuous chamber and especially floor-chamber and block development systems for drilling wells.
It is used for drilling vertical and inclined, mainly explosive wells.
