摘要
Abstract
Gas drainage is an important technical means to prevent gas emission from coal seam, but in the actual process of coal mine gas drainage, restricted by construction technology and conditions, the gas extraction efficiency is low, seriously restricting the safe and stable production of the later mining. In order to solve this technical problem, Lu'an Group, after technical research, puts forward the technology for improving bedding drilling efficiency of gas drainage, which has been applied in 1211 working face gas drainage, and has achieved a remarkable success.关键词
