Rock Falls

Investigation into improved systems for making safe
The primary output of this phase1 of the project was to develop a list of alternative designs for “making safe” that may be considered by SIMRAC. Workers responsible for “making safe” in mines will use the device or
Infra-red thermography of loose hangingwalls
This project is the continuation of GAP706 “Pre-feasibility investigation of infrared thermography for the identification of loose hangingwall and impending falls of ground”. The main concept behind the infrared thermography
Improved techniques to detect unsafe HW conditions
Impact of geotechnical factors on secondary extraction of coal
The literature review identified geotechnical factors impacting on unplanned secondary coal extraction. These factors are grouped into nine broad classes of factors; namely, stratigraphy, rock /coal engineering properties, spontaneous
Guidelines for the design and testing of Thin Sprayed Linings
Thin Sprayed Liners (TSLs), as well as shotcrete and mesh, are mainly used to provide a better support coverage in mining excavations. While it seems evident that increased support coverage leads to improved stability around mining
Fracture zone models to inhibit the effects of rockfalls rockbursts
Experimental investigation of mining induced fracturing
The safety of mining operations is significantly influenced by the in situ stress fields in which the mining excavations are created.  Many in situ stress measurements have been carried out for mining and civil engineering projects in
Evaluation and upgrading of stress measurement data
The safety of mining operations is significantly influenced by the in situ stress fields in which the mining excavations are created.  Many in situ stress measurements have been carried out for mining and civil engineering
Efficient stope and gully support system design
Effective support for tabular stopes Continuation Project 3
The first enabling output of the original rockfall project entailed an optimisation of the current rockburst design and modification of units to suit shallow mine conditions.  The concept was to modify the current system design (SIM
