Discussion on Installation Mode of Methane Sensor in Cutting Face with Special Arrangement of Coal Mine Underground

The paper analyzed and discussed existing problems on setting of methane sensor in cutting face of coal mine underground and other special spaces when ventilation arrangement mode is different with ventilation arrangement mode of AQ1029-2007 ,and gave improved setting methods of methane sensor.It improved using methods of safety monitoring and control system of coal mine and detecting instrument,which has important significance for eliminating monitoring blind area of gas and ensuring safety production of coal mine.
