| Abstract: | Remained gas content is an important basic parameter of gas control in protected coal seam,which is also a basic index to assess its protective effects.The calculation of remained gas content is based on moving law of pressure-relief gas in protected coal seam,it makes use of coal quality industry analysis value and gas adsorption experiment,combined with Langmuir formula.Finally,the calculation method of remained gas content can be obtained. |

| Keywords: | protected coal seam the lower protective layer gas moving law remained gas content |
