The copper-gold orebodies of the Ok Tedi project are located in an area of climatic and topographic extremes, where both the landforms and the rocks from which they have developed are so young that it may be said that geological and engineering processes are coincident.
This report describes the results of ACARP research project C9007. The project was established to assist an innovative roadway development trial at Kenmare 2, South Blackwater Mine. A continuous highwall mining system (CHM) was used to develop the roadways for a proposed punch longwall operation at Kenmare 2. The aim of the research project was to ... Moremonitor, evaluate and model the roadway performance during the initial roadway driveage and subsequent widening using CHM.

The roadway development trial was conducted in January 2000. Significant roof falls were experienced, which contributed to much slower mining progress than anticipated and the operation was terminated prematurely. Despite this, most of the tasks originally proposed within the ACARP project have been completed. They comprise:

Monitoring of roof deformation of a punch longwall roadway.

Laboratory investigation of roof rock properties.

Analysis and modelling of roof behaviour of punch longwall roadways.

The main outcomes of the ACARP research project are the observations and conclusions listed below:

Extensive roof falls, mostly in a range from 0.3 m to 0.7 m, were observed to have occurred in a large portion of the roadway.

The roof rocks within 1.5 m from the coal seam were tested to be weak.

An improvement in roof stability with penetration distance was observed and it could be due to (1) a general increase in the strength of the roof rocks and bedding planes; (2) an increase in horizontal to vertical stress ratio and thus the magnitude of the horizontal stress.

The deep-hole surface extensometers successfully recorded data associated with the development of an unsupported roof fall at 41 m inbye. The stand-up time of the roof was measured to be 10 hours at this location after driveage of the roadway.

The numerical model and the analytical formula designed to analyse the span stability were demonstrated to be effective in predicting the roof falls.

The experience at Kenmare 2 highlights the significance of geological variation and the need for improved understanding of the roof behaviour. Despite the site investigation and geotechnical assessment performed before highwall mining commenced, it is clear from this experience that future highwall mining operations of this nature require more specific information from the area to be mined. This is especially important when mining near to the highwall and in proximity to pre-blasted slopes or in other areas of doubtful roof rock quality.

Despite the early termination of the mining trial, the ACARP research project as a whole is considered to be successful, and the outcomes will be useful for future punch longwall and highwall mining operations. The instabilities of the unsupported roadway span experienced during mining were able to be observed and monitored. This provided a unique opportunity to study the failure mechanisms of unsupported spans at shallow depths and to verify the existing prediction tools.

The innovative method of using a CHM system to develop roadways for a punch longwall operation could well be successful at a site with conditions more favourable to highwall mining.
This is the final report for the ACARP research project, C8033, "Optimal Design and Monitoring of Layout Stability for Highwall Mining". The aim of the report is to provide general guidelines for highwall mining design. The guidelines will help guide mining engineers through the process of feasibility evaluation to final execution of highwall mining ... Morein their mining lease. Purely economic matters, however, are not addressed. A number of new tools for feasibility studies, including the Highwall Mining Index (HMI), the Auger Mining Index and Percentage Extraction estimate are presented in the report.

The key components of this report include:

Feasibility study. The geotechnical evaluation to determine whether the site is suitable for highwall mining. A highwall mining index method is presented to help the decision making process in Chapter 2. 

Site investigation. If the site is considered likely to be a suitable site for highwall mining, geological and geotechnical investigation in the mining reserve (e.g., drilling, highwall mapping, highwall hazard identification etc.) includes the gathering of data for layout design. The new data can also refine the results of the feasibility study. Guidelines for conducting the site investigation are outlined in Chapter 3.

Span stability assessment. Evaluation of the stability of the entry spans, which are unsupported, to ensure the success of mining. This needs to be investigated before the commencement of mining. Assessment tools and methodology are presented in Chapter 4.

Layout design. A layout design to specify pillar size and whether barrier pillars are to be left between panels. An optimal layout design will maximise the recovery whilst minimising the risk of unacceptable instability. Pillar design tools and a new panel stability theory are presented to help in the evaluation in Chapter 5.

Design verification against past experience. A number of panel/roof instabilities have been recorded in the past. A selection of these have been back-analysed and the major causes of the instabilities summarised in Chapter 6. Lessons learned from these studies may be used to provide a final check of the design for the current site.

Mining operation and feed-back. Monitoring of the stability of the highwall, spans and pillars during mining are critically important to a continuous, smooth mining operation. After mining operations have commenced with the designed layout, mining difficulties may occur if unexpected ground conditions are encountered. This may necessitate a change in layout design. Guidelines for conducting monitoring and information feed-back during mining are provided in Chapter 7.

The final report is presented in a user-friendly web style format. Most of the new tools developed within this project, including the Highwall Mining Index (HMI) and Percentage Extraction estimate, are provided in interactive forms. These interactive tools make it easy for users to perform their own evaluation of a site for highwall mining.
