潘一东项目部第一副井主要是服务于－850m以上的开采水平，该井筒要穿越13－1煤与12煤组成的高瓦斯突出煤层组，为了实现安全快速的揭煤，该项目部根据现场的实际情况，采用了多项新技术实施防突措施：首先使用高压充气法快速测定了煤层瓦斯压力，与此同时利用自行研制的取芯器实现完整钻取煤芯，掌握了煤层具体信息；在验证所揭煤层无突出危险性后，再利用扩槽钻头施工大直径的钻孔以加快瓦斯的排放。经过一系列严密组织和紧张施工，整个揭煤过程不到20天，较常规工艺缩短了近1／3的时间，取得了经济效益和安全效益的双赢。

The first auxiliary shaft of Panyidong project department is served for minting area above-850m ,it will cross the high gas and outburst group be made of 13-1coal and 12coal . The In order to accelerate uncovering coal safely ,a number of new technology of outburst prevention were adopted by Project department :At first ,the coal seam gas pressure has been rapidly determined used the method of high gas inflation;At the same time ,the self-developed corer was used to achieve complete coal-core ,and the specific information of coal seam were mastered .After the uncovered coal has been verified and has no outburst ,large diameter drillings were constructed by the expansion slot hole and were used to speed up the gas emissions . After a series of rigorous organization and tight construction ,the whole process of uncovering coal is in less than 20 days ,and nearly a third of the time was shorten compared with conventional process ,a win-win situation of the economic and security benefits are gained .
