Abstract
The main objective of this work is to analyze the vibration, to find the sources and to examine for optimal solutions in SBR-160A-24 auger drilling rig. Design and modelling are based on result of this research work.
Auger drilling rigs used in ‘Baganuur LC’ coal mine. The company spends half of its expenses of operations costs on auger drill bits. There are a number of reasons such as rotational speed of drill is a constant for drilling different hardness material in layers.
Currently, they do not have any monitoring and automatic control system to manage the current of motor and the rotational speed. The machine can work under high vibration itself and a monitoring system with smart sensors are not suitable for under high vibrations. The experimental result was proved the auger drill rigs had a high vibration.
Thus, it leads to the bachelor thesis is researched vibration causes and their influence.
From the measurement results, the vibration reducing solution founded and there some calculation and analysis of modelling done as needed.
