Abstract
Compressed air is the most common type of energy used in underground mines. Despite its low efficiency and high cost, it is used for various purposes, especially for drilling. This type of energy is still used relatively frequently, mainly due to its safety benefits and technical matters even though it is generated with a premium in relation to electrical power. However, compressed air that looks to be safe, could cause major accidents in mines and during the installation. The air receiver is similar to any pressure vessel and requires periodic technical inspection to ensure the accuracy of the vessel and its safety devices. In this paper authors try to elaborate on different circumstances, control and calculations surrounding pressure vessels whilst inspecting, based on division 1 section VIII ASMI standard. The results obtained could be used in all underground mines where compressed air is used as a form of energy.
