| 摘 要： | 在煤矿钻探过程中,当遇到含水层的水量、水压很大时,在孔口安装防喷装置是有效控制、防止井喷事故发生的基础保证。新型钻孔防喷器的研制,解决了井下高压喷水和控制钻孔水量的问题,大大提高了煤矿钻探的安全系数。 |
| 关 键 词： | 高水压 井喷 安全系数 |

| Abstract: | Installation of blowout preventer in orifice was basic guarantees which effectively controlled and prevented accident of blowout,facing with great volume and big water pressure in aquifers in process of drilling in coal mine.The study of a new drilling-hole machine resolved the problems of high pressure water-jetting in underground and controled water volume of borehole,greatly improved safety factor of drilling. |
| Keywords: | high water pressure blowout safety factor |
