城门峒尾矿库坝体预埋辐射排渗法技术研究及应用

浸润线是衡量尾矿库坝体安全稳定性的重要技术指标之一,浸润线位置的高低对坝体的应力、抗剪强度以及坝坡稳定性影响较大,针对传统治理方法施工难度大,费用高等缺点,创新一种尾矿库坝体深层预埋辐射排渗方法,施工难度小、费用低廉、降水面积大、效果好。通过南山矿城门峒尾矿库坝面排渗主管、辐射排水管的制作,预埋铺设,有效无动力外排了未来各期子坝深层的渗透水,降低了坝体的浸润线,满足浸润线设计要求,确保了坝体的稳定。经济效益和安全效益显著。

输干井联合水平放水孔排渗法在滑坡治理中的应用

露天矿在采剥过程中,由于地区降水量的影响及部分岩层遇水软化的特征,导致边坡内形成上层滞水,地下水水位上涨,存在滑坡安全隐患。采用输干井联合水平放水孔排渗法,实现了水位的下降,保障了滑坡治理工程的安全有序进行,治理效果显著。

尾矿库排渗工程技术方法

为消除或减少尾矿库的安全风险,重要措施就是降低尾矿库坝体内的浸润线,而排渗工程技术方法是其主要手段。本文结合部分岩土工程技术在尾矿库排渗工程中的运用,并通过多项工程实践,系统讨论与总结尾矿库排渗工程技术方法中的盲沟排渗法、水平孔排渗法、辐射井排渗法、井点管抽水法、其它联合排渗措施的原理特点、施工方法与质量控制要点。

Fifty-six Cases of Protrusion of Lumbar Intervertebral Disc Treated by Penetration and Oral Administration of Chinese Decoction Plus Traction

Fifty-six cases of the protrusion of the lumbar intervertebral disc in the treatment group were treated by drug-penetration and oral administration of traditional Chinese decoction plus traction, and the other 35 cases in the control group by oral administration of Chinese decoction and traction. The results showed that the cure rate in the treatment group was 83.9%, and that in the control group was 57.1%, with a statistically significant difference between the two groups (P<0.01), indicating that the former is a more effective therapy for protrusion of the lumbar intervertebral disc.
