Abstract

Rock mass classification is used as an important parameter in determining rock reaction to a construction, one of several rock mass classification methods is point load test. Point load test is preferred because of its ease in determining rock mass classes, both in terms of cost and time. Until now, many research results have been found that discuss the point load test with the aim of reducting the error value from the test result. In this research, a literature review was conducted from several research results to find outlines of things that must be considered and determine its superiority in converting to other test values. The results showed that the operator's ability, cone plate geometry, periodic tool maintenance, loading arm length and sample geometry as things to consider in point load test and point load index value can be converted to uniaxial compressive strength value, taking into account the geological conditions and correction values for each rock type.Keyword : PLT, rock mass classification, tool, test

Abstract

Blasting activities cause ground vibrations that affect the potential for ground displacement in surface mining. That will have an impact on the stability of the slope and environmental problems. Therefore, it is necessary to analyze the prediction ground vibrations measured by peak particle velocity (PPV). Artificial Intelligent (AI) has an important role to overcome the limitations of parameters used, uncertainty, and inaccuracy than conventional methods. AI for prediction ground vibration has grown a lot in recent years. To find out an accurate and effective AI technique, the authors compare several techniques by evaluating their strengths and weaknesses based on literature studies. The ICA-M5Rules model and ICA-ANN model are techniques that have high accuracy and flexibility of use than other presented techniques. And related to the use of parameters, there are other parameters that play an important role which will be reviewed in this journal.

Abstract

Rock strength can be known from it's physical and mechanical properties which are strongly influenced by weathering. It requires a lot of time and research cost to find out about the effect of weathering on rock strength in various types of rock, therefore research was conducted in a literature review. The higher of weathering class affect the decrease of rock strength.
