| Abstract: | In order to solve the problem of gas control in the working face of high gas area in low gas mine,in view of the fact that the 3105 working face of Sihou Coal Industry needs to pass through many geological abnormal areas during the mining period,there is a hidden danger that the gas in the upper corner of the working face exceeds the limit.Through the establishment of gas monitoring system and the adoption of gas control technical measures such as top corner cutting control hanging roof,top corner gas drainage and high-level drilling drainage,the problem of gas overrun in the upper corner of the working face can be effectively solved. |
