基于Matlab采空区自燃“三带”数据处理的研究

Research on Data Processing for Spontaneous Combustion Three Zones in Goaf Based on Matlab

为了更好的划分采空区"三带"宽度,采用Matlab软件对束管检测数据进行处理,在基于氧浓度指标法前提下采用残差图剔除不可靠点后二维曲线的精确拟合计算方法以及采空区走向、倾向、氧浓度的三维等值线法直接观测"三带"范围。两种方法相互验证,最终通过应用Matlab软件的精确处理,得出采空区最大氧化带宽度为:30.4～158.95 m;最小氧化带宽度为:32.17～158 m。

In order to better divide ＂three zones＂ width in with software Matlab. Removing the unreliable points with goaf, detection data from bundle tubes were processed the residual case order plot, employ precise fitting cal- culation method of two dimensional curves based on the oxygen index method, and adopt three dimensional con- tour method based on the strike orientation,tendency orientation and oxygen concentration of goaf, then observing three zones range directly. With the two ways to mutual authentication, finally, process the data precisely through the application of Matlab software, it is concluded that the maximum oxidation zone width： 30.4- 158.95m and the minimum oxidation zone width ： 32.17 - 158 m.
