Integrating robotic systems in underground roof support machine

Abstract

Traditionally, the roof bolting process is performed manually by skilled workers, which is time-consuming and labor-intensive. This often exposes human operators to several risks. Bolt installation in underground coal mining operations involves moving and manipulating heavy tools quickly while ensuring the safety of the area. Hence, humans must relocate from an active mining site to a more secure place where the operator can control and monitor the roof bolting process. This study explores the integration of a six-axis robotic arm and other specialized novel technologies into an existing roof bolter machine to automate the roof bolting module, therefore replacing human duties. Owing to the harsh mining conditions in underground coal mines, the integration of robotic systems requires proper planning to ensure reliable and safe operations. The methodology adopted for integrating the robotic system in this study may be regarded as a conceptual framework for the automation of underground mining roof bolting operations. This study highlights certain specifications that should be considered when automating underground mining machines. The results showed that a robotic arm that performs human tasks during roof bolting operations can be successfully integrated into a roof bolting module by establishing a robust communication network to facilitate seamless interaction between different hydraulic, mechanical, and electronic components.
