In China, almost 70% deaths of the mine accidents are caused by gas explosion and  HYPERLINK javascript:void(0); outburst? HYPERLINK javascript:void(0); of? HYPERLINK javascript:void(0); gas. This indicates that coal mine gas ranks the first in threatening the coal mine safety. The key point to improve the safety of coal mine production is that keep a regular monitoring and managing the coal mine. To achieve this goal, we need to first know the properties of the gas and its distribution in the coal bed so that we can optimize the ventilation design, and do a better job in gas drainage. In this paper, kriging interpolation method is adopted to study the coal mine gas. Through the System Implementation of the Analysis of Coal Mine Gas Properties Based on Kriging Interpolation, the distribution of coal mine gas in coal bed is better displayed. Also, people can accurately determine and forecast the mine gas concentration and the emission zone and agglomeration. Consequently, the coal mine safety production will be greatly improved; disasters like gas explosion and gas outbursts will be hugely reduced; and finally get us a safe and profitable coal mine environment.
