Method for mounting a roll of protective mesh material to an underground rock drilling machine, a method for attaching protective mesh material to a rock surface and a mounting device

A mounting device, which is configured to mount a roll of protective mesh material to a drilling boom of an underground rock drilling machine according to a method including at least the following steps:

• inserting a first end of a first bar from a first lateral side of the roll of protective mesh material into a center of the roll of protective mesh material;
• fastening the first bar directly or indirectly to the drilling boom;
• inserting a first end of a second bar from a second lateral side of the roll of protective mesh material opposite the first lateral side into the center of the roll of protective mesh material;
• fastening the second bar directly or indirectly to the drilling boom in a location that is spaced apart from the first bar;
• and
• securing the roll of protective mesh material against autonomous unrolling, wherein for securing the roll of protective mesh material against autonomous unrolling, the roll of protective mesh material is tensioned by applying a pressure to at least one of the lateral sides of the roll of protective mesh material or wherein in order to secure the roll of protective mesh material against autonomous unrolling, the roll of protective mesh material mounted to the drilling boom is tilted in such a way that the protective mesh material of the roll of protective mesh material rests on a left side of the drilling boom or on a right side of the drilling boom;
• wherein the mounting device has at least a first bar and a second bar, wherein each bar comprises a section that is adapted to be inserted into a center of the roll of protective mesh material and to bear a weight of at least 100 kg when the bars are used to lift the roll of protective mesh material, and wherein at least the first bar comprises a fastening unit, which is adapted to mount the first bar to a shank of the drilling boom by at least partially encompassing the shank.
