Abstract: Taking No.12 Coal Mine of Pingdingshan Tianan Coal Industry Co., Ltd. in the east of Pingdingshan mining area as an
example, based on the analysis of the characteristics and causes of gas accumulation in the return air corner of the working face in
combination with the geological exploration data and the actual situation of the working face, this paper put forward gas prevention
measures and suggestions from the perspectives of the use of wind curtain and air guide curtain, pressure equalizing ventilation,
setting extraction pipeline, gas monitoring and early warning, which has reference value for ensuring that the gas concentration in
the coal mining face is in the normal range and ensuring the safety and efficiency of the coal mining process.

Key words: mine; coal mining face; return air corner; gas prevention and control
