Pneumatic percussion tool to implement adaptive technologies

Authors: Plokhikh VV

The modern technologies based on vibration impact find wide application both in surface and underground mineral mining. The impact source is mostly a pneumatic percussion tool. Such equipment is used in hole-making and in other types of mining activities. The compressed air-driven impact machines are advantageous for simple design and reliable operation in unfavorable conditions. Deeper level mining faces with the acute necessity to ensure safety of personnel when operating in highly gassy air. One of the ways of solving this problem is engineering of pneumatic percussion tools suitable for implementation of adaptive technologies. These technologies enable application of the remote drilling control, and the tools can operate as parts of robotic drilling facilities capable of automatic unmanned functioning. A feature of the adaptive drilling technologies is the ability of an impactor to vary the size and mechanism of impulse in a wide range subject to properties of a medium being treated. The proposed construction diagram of an air impact tool allows adjustment of output energy parameters immediately in operation. The implemented simulation modeling of the pneumatic percussion mechanism proves feasibility of its physical modeling. The physical analogue model test produces an indicator diagram of the tool work cycle, and the graphs of change in energy and dynamic parameters of the tool are plotted.

Keywords: adaptive technologies, robotic drilling facilities, pneumatic percussion tool, elastic valve, construction diagram, simulation model, physical model, work cycle, energy parameters, dynamic parameters.
