Abstract

There are many factors which affect coal production processes and the safety of colliers in coalmines. Among them, there are especially three key factors, the temperature T, the atmospheric pressure P and the gas concentration C that need synthetically to be considered. However, the conventional strategies of environmental measurement only considered the effect of T, P, or C without any systematic, therefore there have been difficulties to make a comprehensive evaluation. Accordingly, the authors present a new method based on a secondary data merging mathematical model which synthetically considers the influences of T, P, and C with an adaptive-weighted data fusion method based on the Dempster-Shafer evidence theory, leading to an optimization of the environmental measurement parameters. This method not only ensures the completeness of the data source but also improves the accuracy of the detection systems for a coal mine. It especially enables a new exploration and research about environment detection processes.
