Strip mine pit large-water-inflow spring hole group water plugging method
A strip mine pit large-water-inflow spring hole group water plugging method comprises the following steps that S1, structural inference, drilling verification or geophysical prospecting analysis is conducted in a mine pit and on the periphery of the mine pit, and the position and the water flow direction of a water passing channel are determined; s2, diversion pressure relief holes are constructed, specifically, the diversion pressure relief holes are drilled in the upstream direction of the water passing channel within the range of 4-10 m away from the water gushing spring opening group; s3, grouting holes are constructed, the grouting holes are drilled between the water gushing spring opening group and the flow division pressure relief holes and within the range of 1-4 m away from the water gushing spring opening group, and after drilling is completed, the holes are sealed through a bag type hole packer; s4, a back pressure layer is arranged above the water gushing spring opening group, and back pressure treatment is conducted on the water gushing spring opening group; and S5, the water gushing spring opening group and the grouting holes are blocked by pouring quick-setting slurry into the grouting holes. The defect that in the prior art, in-situ pressure relief is carried out on a water gushing spring opening is overcome, flow control and speed reduction can be rapidly and effectively carried out on a water passing channel, grouting slurry is easier to preserve and solidify, curtain grouting is easier to succeed, the construction time is shortened, special equipment is not needed, and local materials are easily used.
一种露天矿坑大涌水量泉眼群堵水方法，包括以下步骤：S1：在矿坑内和周边进行构造推断、钻探验证或物探分析，确定过水通道的位置和水流方向；S2：施工分流泄压孔，在过水通道上游方向，且距涌水泉眼群4‑10m范围内钻分流泄压孔；S3：施工注浆孔，涌水泉眼群和分流泄压孔之间，且距涌水泉眼群1‑4m范围内钻注浆孔，钻孔完成后用囊式封孔器封孔；S4：在涌水泉眼群上方设置反压层，对涌水泉眼群进行反压处理；S5：通过向注浆孔灌注速凝浆，对涌水泉眼群及注浆孔进行封堵处理。改变了现有技术在涌水泉眼原位进行泄压的缺点和不足，能够快速有效地对过水通道控流降速，注浆浆液更容易留存并凝固，帷幕注浆更容易成功，且施工时间缩短，不需要特殊设备，易于就地取材。
