底板注浆加固技术在告成煤矿的应用

Application of Bottom Grouting Strengthening Technology in Gaocheng Coal Mine

文章主要介绍了郑州煤电公司告成煤矿25091工作面煤层隔水底板注浆加固技术。通过对煤层隔水底板实施注浆,不但加固了底板,也保证了工作面的安全生产。经过检验钻孔出水量、物探验证及工作面实际回采情况,证明了煤层底板注浆加固技术的合理性和实用性。目前该技术已在郑煤集团个矿得到广泛应用。

This paper mainly introduced the coal seam in Gaocheng Coal Mine of Zhengzhou coal company in 25091 working face of water resisting floor grouting technology.By grouting the seam floor, not only the floor was strengthened, but also the safe production of the working face was ensured.It was proved that the grouting and reinforcement technology of the coal seam floor is reasonable and practical through the inspection of the water discharge of the borehole, the verification of geophysical exploration and the actual recovery of the working face.At present, this technology has been widely used in Zhengzhou Coal Group.
