The film discusses the history and importance of rock bolting in underground mining, highlighting its role in ensuring miner safety by providing ground support. Early miners relied on timbering, but as mining methods evolved, rock bolting became the preferred method due to its effectiveness and efficiency. The installation process, types of bolts, and the significance of proper tension and torque are emphasized, as well as the advantages of rock bolting over traditional timbering, including better ventilation and reduced risk of collapse. The film concludes by stressing the need for management to implement effective ground control programs and for miners to adhere to these protocols for a safer working environment.
