The coal mine gas emission anomalies and gas dynamic phenomenon hare usually occurred in the early of headwork, coal mine gas disaster are serious in Hongxiayijian Coal Mine. In order to ensure coal mine production safety and reduce the gas content of coal, the coal mine gas should be drainaged before driving. It is the key of the judgment of gas drainage standards that the gas content measurement is accurate or not. The Hongxiayikuang Coal Mine did lots of practice on coal mine gas measurement, summed up an important experi- ence for accurate measurement of gas content, actived effective guidance for the gas drainage work and ensure coal mine safety production
