    Practice of Gob-side Entry Driving Outburst Prevention in Xin'an Coal Mine

    • 摘要: 通过对新安煤矿14171上巷沿空掘巷技术应用效果的考察,得出突出煤层掘进巷道时,在采空面卸压区域的保护下,辅以掘进工作面区域预测及超前探孔和区域瓦斯抽采达标评判三重防护手段对掘进期间的消突效果,能够保证沿空掘巷在安全的环境下实现顺利消突及快速掘进的目的。

       

      Abstract: Through application effect investigation of gob-side entry driving for 14171 upper roadway in Xin'an Coal Mine, under the protection of gob relief zone, three kinds of protection method including regional forecast in heading face, advanced exploration holes and the reaching standard of gas drainage are used to evaluate eliminating outburst effect during driving roadway in outburst coal seam, which can ensure to achieve the purpose of outburst elimination and rapid driving under the safety environment of gob-side entry driving.
