Abstract

The purpose of this research is the development of Flat Jack tool that will be used to determine the value of stress on the wall, convergence value to monitor the roof deformation, the geological structure condition or the general straightness in the research area, stand up time for as reference in the mounting of the buffer. The research was conducted in mining laboratory of Mining Engineering Department of FT-UNP and underground mining location in Sawahlunto. In this activity, there are also several factors that will be explored in controlling the stability of the roof and walls of the underground mine, namely the natural stress (Virgin Vertical Stress), the induced stress (Measured Vertical Stress), the depth, the convergence value, the geological structure or the general alignment, and the parameters weighting of rock mass including PLI compressive strength (Point Load Index), Rock Quality Designation (RQD) value, solid spacing, solid condition, ground water condition, and stacked discontinuity orientation. This type of research is quantitative research. In this study how to analyze stress value that is between virgin vertical with measured stress. For convergence data is described as a trend, as well as analyze the weighting (RMR) and geological structure at the Work Location Underground Mine in 2017. The main tool used in this study is to measure the stress value of a flat jack tool, to measure the value of convergence measured by stick convergence rod. And for the measurement of geological structure using geological compass, meter, and digital caliper. The results of this research are just at the design stage of development of tools: 1). Flat Jack tool that is in this design is the development of Flat Jack tools that already exist and more need to be in uci try. 2) Flat Jack and convergence rod tools can be used in field measurements. 3) More broadly developed tools can be used for research in assessing the stability of underground mine tunnelwall and provide information to the company to know the stability of the rocks on the roof and underground mine tunnel walls.
