Ground Support Insertion Tool Anchoring Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ground support member insertion devices in mining operations require significant force, leading to lateral destabilization and potential damage to the support member and hazards for operators due to lack of stabilization during insertion through pre-drilled holes filled with resin.
Innovation Solution
An improved ground support member insertion device with a clutch assembly and anchoring means attached to a jackleg drill, featuring a rectangular channel for stabilization, a roller for frictional engagement, and an anchoring member to resist lateral forces, ensuring stable insertion and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If significant force is applied to push the ground support member into the resin-filled hole, then the ground support member can be inserted into the hole, but lateral forces are created that destabilize the apparatus and may damage the ground support member
Solution Approach 1:
The patent applies preliminary action by pre-drilling a second, shallower hole and pre-installing an anchoring member into it before the main insertion operation. This preliminary anchoring structure is prepared in advance to provide stabilization during the forceful insertion of the ground support member through the resin-filled first hole, preventing lateral destabilization without compromising the insertion process.
Solution Approach 2:
The anchoring member acts as an intermediary element between the ground support member insertion process and the rock formation. It is installed in a separate pre-drilled hole and serves as a stabilizing mediator that resists lateral forces generated during insertion, thereby protecting both the apparatus and the ground support member while allowing the insertion to proceed.
2Productivity
If significant force is applied to push the ground support member into the resin-filled hole, then the ground support member can be inserted into the hole, but the jackleg drill and pusher leg move and swivel which creates worker hazard

3Device complexity
If the pusher leg is not supported for lateral loads, then the apparatus remains simple, but the lateral forces created during insertion destabilize the apparatus
Solution Approach 1:
The patent applies segmentation by separating the stabilization function from the main pusher leg structure. Instead of making the pusher leg itself complex and load-bearing for lateral forces, the system segments the stabilization function into a separate anchoring member installed in a independent second hole. This allows the pusher leg to remain simple while the overall system achieves stability through the separate anchoring component.
Solution Approach 2:
The anchoring member acts as an intermediary element between the ground support member insertion process and the rock formation. It is installed in a separate pre-drilled hole and serves as a stabilizing mediator that resists lateral forces generated during insertion, thereby protecting both the apparatus and the ground support member while allowing the insertion to proceed.

The solution provides stable and secure insertion of ground support members into resin-filled holes, preventing damage and reducing operator hazards by resisting lateral forces and ensuring proper alignment and tensioning.
Implementation Method 1
The roller is adapted for frictional rolling engagement with the ground support member
Implementation Method 2
The anchoring member is adapted for resisting lateral forces resulting from resistance to the ground support member being inserted

AI summary
An improved ground support member insertion device comprising means for attaching the device to a jackleg drill, a clutch assembly disposed adjacent to the attaching means and adapted for holding a ground support member while it is being inserted into a first drill hole; and, anchoring means disposed opposite the clutch assembly and adapted for temporarily anchoring the device for stabilization in a rock formation during insertion of the ground support member. An impact tool for engaging the proximate end of the ground support member providing rotation and impact to the ground support member to mix the resin and to secure the ground support member in a rock formation. The impact tool can also be used to manually or mechanically tension the ground support member once installed.
