Abstract


The main research work for our existing gas drainage technology the gas drainage theory applied to the gas drainage actual work which , in order to achieve safe and efficient production . Domestic and foreign gas drainage technology , summarizes our gas drainage problems , through research, to master the migration of gas in coal seams and surrounding rock during mining and liquidity rules and mechanized mining ( put ) face Methane concentration distribution ; explore the determination and calculation methods of the various parameters of the gas drainage system , and summarizes the various methods to mine gas drainage ; analysis of gas drainage in low mainly due to the proposed an effective way to improve gas drainage rate , and face to N2-702 Daxing mine gas drainage system transformation example , laid the foundation for future Daxing mine gas drainage work .
