Study of Optimal Wooden Support Patterns on Mine Slopes to Prevent Unwanted Slope Failure
Keywords:
wooden support, slope failure, numerical methodAbstract
Slope failure is a phenomenon that often occurs in surface mines, both on the pit slopes and the disposal slope. One of the most common types of slope failure is a circular failure, which generally occurs on slopes with soil or fractured rock masses. One of the ways that can be done to prevent this circular failure is by installing reinforcement on the mine slopes. Wood or logs are a form of reinforcement commonly used on slopes with soil materials, especially on temporary excavation slopes. Besides being easy to obtain, the use of wood can also reduce costs and is quite easy to implement. However, until now, there are not many guidelines that can be used in installing wood reinforcement in the mining world, especially in Indonesia, which has diverse types of woody plants. This lack of guidelines causes the installation of wood reinforcement in mine slope that is carried out sometimes does not have a strong scientific basis and become ineffective. So, this study will be discussed the effect of various geometrical parameter of the wooden support installation in the mine slope to determine the best possible way to install support. This best geometrical pattern will be the recommended pattern to install wooden support in mine slope.
