【摘要】：针对朱集西煤矿矸石井钢筋混凝土钻井井壁在第54节和59节出现渗漏水现象,进行了出水机理和注浆技术探讨。首先,从工程地质条件、水质化验、井壁混凝土浇筑情况、水力劈裂原理等方面分析,揭示了深厚冲积层钻井井壁渗漏水机理;然后,通过对破壁注浆和地面注浆这2种钻井井筒防治水方案的对比分析,提出采用井筒内破壁注浆方案,并指出在深厚冲积层中进行钻孔破壁时,应采取孔口管防冲出等安全措施,以确保施工人员和井筒安全;最后,进行了相关注浆参数设计,通过工程实践表明,破壁注浆达到了预期效果。
[Abstract]:In view of the leakage phenomenon of reinforced concrete drilling lining of coal gangue well in Zhujixi coal mine in the 54th and 59th sections, the mechanism of outlet water and grouting technology are discussed. Firstly, from the engineering geological conditions, water quality test, well wall concrete pouring situation, Based on the analysis of hydraulic splitting principle and other aspects, the mechanism of wall leakage in deep alluvium drilling is revealed, and then, through the comparison and analysis of two kinds of wellbore water prevention and control schemes, the paper puts forward to adopt the scheme of wall breaking grouting in wellbore. In order to ensure the safety of construction personnel and wellbore, some safety measures should be taken to ensure the safety of construction personnel and wellbore when drilling holes break wall in deep alluvium, and the relevant grouting parameters are designed, and the engineering practice shows that the safety measures should be taken in order to ensure the safety of construction personnel and wellbore. The wall-breaking grouting has achieved the expected effect.
