Description

technical field [0001] The invention relates to a device and method for testing basic parameters of coal seam gas and predicting a gas accumulation zone, belonging to the field of mine gas control and monitoring. Background technique [0002] At present, coal mines have taken many measures to prevent and control gas accidents, but gas accidents still occur frequently, and most of them are major and extraordinarily serious accidents. Sex is not strong. For coal mines, it is very important to measure the gas parameters. Through this work, basic data can be provided for the preliminary design, safety special chapter, and gas drainage design. [0003] The measurement of basic parameters of coal seam gas refers to obtaining the basic parameters of coal seam gas in a certain area through a series of on-site data measurement and laboratory data analysis. Attenuation coefficient, extraction radius and other parameters. However, due to the limitation of site conditions, when testi...
