摘　　要：地面钻井是一种高效的卸压瓦斯抽采技术。针对钻井抽采与煤层赋存条件的适用性问题,归纳出地面钻井抽采被保护层卸压瓦斯消突、地面钻井控制单一煤层卸压瓦斯流场的两种模式。工程应用效果表明,钻井抽采卸压瓦斯效果显著,可彻底消除突出煤层的突出危险性和有效控制采空区瓦斯涌出。Ground drilling is an efficient pressure relief gas extraction technology. Aiming at the applicability of drilling extraction and coal seam occurrence conditions, this paper summarized two modes of pressure relief gas outburst elimination in protected layer by ground drilling and control of pressure relief gas flow field in single coal seam by ground drilling. The engineering application results show that drilling gas extraction has a remarkable effect on relieving pressure, which can completely eliminate the outburst risk of burst coal seam and effectively control the gas gushing out of goaf.
