| Abstract: | In view of W-type ventilation system in Longtan coal mine fully mechanized working face, it is easy to cause gas accumulation and overrun in the middle corner of mining face. Taking 3112 south mining face of Longtan mine as the engineering research background, proposes to take active gas drainage in goaf and implement gas control technology of high drainage roadway, so as to realize the gas limit of middle corner and return air roadway, and ensure the safety production of mine. |
