摘要
研究分析了针对阳泉煤业集团新元公司高瓦斯煤层工作面瓦斯超限状况,依据UDEC数值模拟确定了工作面采动中最大主应力和铅垂方向应力的分布特征,并结合理论计算确定了本煤层瓦斯主抽技术的具体措施。
The study examines the gas gauge problem in high-gassy coal seam of Xinyuan Company,Yangquan Coal Group.Based on UDEC statistic simulation,the maximum primary stress and vertical stress distribution are determined during mining.Specific gas drainage techniques for this seam are also determined by theoretical calculations.
