Description

Technical Field

[0001] The invention belongs to the technical field of mine anchor cable support, and in particular relates to an anchor cable monomer auxiliary operation device. Background Art

[0002] Approximately 90% of my country's coal resources are mined underground, following the principle of "giving equal importance to mining and excavation, with tunneling taking precedence." The tunneling face is the most densely populated and harshest workplace in underground coal mines. Traditional tunneling techniques rely on alternating tunneling and support operations. However, anchoring and support are slow, labor-intensive, and unsafe. Operating equipment is limited in function, lacks coordination, and is inefficient, leading to a serious imbalance between mining and excavation. The current mainstream tunneling technique primarily uses bolting, supplemented by cable anchors. Single-bolt and cable anchor drills are used to support the tunneling face, with support accounting for over 60% of the total tunneling time, severely impacting tunneling progress and coal mining efficiency.
