【摘要】：河北省是钢铁大省,铁矿资源极其丰富。近年来,随着科学技术水平的不断提高,越来越多过去无法开采的矿山也得以开发,包括那些过去因为水患问题而无法开采的矿山。司家营研山铁矿的生产经常受到水患问题的影响,该矿采场东边帮的局部区域于2011年已经施工高压旋喷帷幕一道。然而,由于地层条件不是十分明确、含水层地下水渗透性能未知、地下水水力联系不清,该部位帷幕工程施工完毕后,采场东边帮地下水出水量仍然很大,致使该部位的剥离工作停止,为此必须进行第二轮矿山防治水,否则矿山生产难以保障。以司家营研山铁矿采矿场防治水工程为例,深入开展了方案研究,为第二轮防治水工程的实施提出切实可行的设计方案和施工方案。为了更好的进行第二次防治水工程设计,首先深入研究了司家营矿区的地质和水文地质情况,进一步摸清了地下水力联系。除了弄清地质情况以外,对第一次防治水工程进行了研究和评价,查找不足,为第二次防治水工程设计提供借鉴意见。随后,进行了防治水工程设计多方案的比选,从技术、经济等多个角度讨讨论,确定了地下连续墙的设计方案。最后,在工程实施过程中,采取了部分的技术改进措施和创新研究,包括利用塑性混凝土取代普通硅酸盐混凝土,减少水泥用量,以及创新尝试采用开槽挖出的废弃渣土替代了部分粗骨料等,均有效地节约了工程投资。
[Abstract]:Hebei Province is a large iron and steel province, iron ore resources are extremely rich. In recent years, with the development of science and technology, more and more mines, including those which were unable to be mined, have been developed. The production of Sijiaying Yanshan Iron Mine is often affected by the flood problem. The local area of the east side of the mine stope has been constructed together with high pressure jet curtain in 2011. However, as the formation conditions are not very clear, the groundwater permeability of the aquifer is unknown, and the hydraulic connection of the groundwater is not clear, the amount of groundwater produced from the east side of the stope is still very large after the curtain project is completed. In order to stop the stripping of this part, the second round of mine water control must be carried out, otherwise the mine production is difficult to guarantee. Taking the water control project of mining site of Sijiaying Yanshan Iron Mine as an example, the project is studied in depth, and a feasible design scheme and construction scheme are put forward for the implementation of the second round of water control project. In order to better carry out the design of the second water control project, the geological and hydrogeological conditions of Sijiaying mining area are studied in depth, and the relation of groundwater force is found out. In addition to making clear the geological conditions, the first water control project is studied and evaluated, which is insufficient to provide reference for the design of the second water control project. Then, the design scheme of underground continuous wall is determined by comparing and selecting many schemes of prevention and control water engineering design, discussing the technical and economic aspects, etc. Finally, in the process of engineering implementation, some technical improvement measures and innovative research have been adopted, including the use of plastic concrete to replace ordinary Portland concrete, and the reduction of cement content. In addition, some coarse aggregates are replaced by slotted waste residue, which can save project investment effectively.
