Complex measuring system for longtime monitoring and visualization of temperature and toxic gases concentration

Abstract

The contribution describes a developed measuring system intended for long-term monitoring of temperatures and hazardous gas concentrations within old mining dumps affected by thermal processes. It includes a short introduction describing the creation of thermal processes, including related hazards and impact on the environment. Furthermore, the contribution provides a detailed analysis of sensors for measuring CO and CH4 gas concentrations. It provides the advantages and disadvantages of the individual sensors, including the experience with their use. The conclusion contains a description of the complex measuring chain, including the data transfer technology and visualization at the dispatching station.
