Abstract: The paper analyzes the development trend of gas extraction in recent years and summarizes the intelligent extraction that acquiring the extraction signal to determine the state of drainage system and predict the occurrence of accidents, taking relevant measures to reduce the accident rate and decrease losses. At the same time, according to the extraction concentration, extraction flow, extraction negnative pressure, the economy and rationality of extraction is determined, which realizes the intelligent drainage of system and achieves safe, economic and efficient extraction.
