摘　　要：以东大煤矿回风立井揭穿突出厚煤层为工程实例,对揭煤期间的若干关键问题进行了探讨。通过东大矿的成功实施,总结出一种简单有效的下向钻孔瓦斯压力测定方法,并形成了一套井筒揭穿突出厚煤层期间的区域措施及效检、爆破及支护措施,以及在煤层段的防突技术,保证了井筒安全顺利的揭煤。Take the Dongda coal mine return air shaft uncover the thick coal seam with coal and gas outburst as an engineering example, the several key problems of uncovering coal during have been investigated. Through the successful implementation of the Dongda coal mine, a simple and effective method to determine the gas pressure was summarized. The regional measures and effective inspection, blasting and support measures.
