Abstract

Gas extraction is one of the means to control gas disasters in coal mine production. Coal mine gas is not only a major disaster source, but also an important clean energy. Gas extraction drilling technology is the main technical means of underground coal mining. With the increase of mining depth, gas pressure, content and outburst risk increase significantly. Efficient extraction and accurate early warning have become the core issues to ensure mine safety and resource utilization. This paper systematically reviews the research progress of gas extraction drilling technology optimization, extraction effect evaluation method and intelligent early warning mechanism, and looks forward to the future development trend of new technologies.
