[0002] Gas is a colorless, odorless gas, the main component of which is methane, and sometimes also contains small amounts of carbon dioxide, nitrogen and other gases. In coal mining, gas is a major safety hazard. Gas extraction is an important coal mine safety production measure used to reduce the gas content in the mine and improve mine safety. When gas extraction is carried out, it is usually necessary to extract the gas from the coal seam by drilling. In order to ensure the effective extraction of gas, drilling and sealing is a very critical step.
