Study of Gas Concentration Based on the Least Square Method and Polynomial Fitting
To make full use of the gas detection data of coal monitoring and control system and master the change rule of gas concentration accurately, the paper listed a portion of gas concentration recorded in January and obtained the calculating formula of gas concentration, fitting curve, qualitative and quantitative analysis and residual illustrations on the basis of Matlab mathematical software, least square method and polynomial fitting to estimate the mine gas density at the rest time of January.The result has higher related coefficient and smaller error.Thus, the change rule can help to analyze the real — time data and make the reasonable judgment and decision.
